1.1 Structure

In conjunction with permitted drives and measuring systemsas well as with a proportional directional control valve typeMPYE-5-..., the SPC11 enables:

– fast movement into the mechanical end positions and oneor two selectable intermediate positions

– manual movement between the end positions.

The end position cushioning, movement to the intermediatepositions and manual positioning are electronically con-trolled. A distinction is made between the following types ofSPC11:

Type Description

SPC11-POT-TLF Enables connection to the linear potentiometertype MLO-POT-...-TLF.

SPC11-POT-LWG Enables connection to the connecting rodpotentiometer type MLO-POT-...-LWG and therotary drive with integrated measuring systemtype DSMI-...

SPC11-MTS-AIF-2 Enables connection of the linear drive withdigital measuring system type DGCI-... .

SPC11-MTS-AIF Enables connection of the linear drive withintegrated digital measuring system typeDGPI(L)-...-...-...-AIF or the digital measuringsystem type MME-MTS-...-AIF.

SPC11-INC Enables connection of an incrementalmeasuring system (e.g. piston rod drive withintegrated incremental measuring systemtype DNCI-...-...).

With the SPC11, movement is controlled. During commission-ing, the end positions (cylinder end positions or position ofthe fixed stops) as well as the desired intermediate positionsare “learnt” by the SPC11.



During operation, the SPC11 controls movement of the move-able mass into the saved end positions and intermediatepositions at the highest possible speed. Shortly before the“learnt” end position or intermediate position is reached, themoveable mass is braked so that it comes to a standstill.

To keep the moveable mass in the “learnt” end position, it ispressed against the fixed stop (typically at a pressure that isslightly less than the operating pressure).

Advantages

Compared to impact-limited drives with pulse-valve control,this control procedure permits higher positioning speeds.Also, the following measures, which would be required forcontrolling a drive with a pulse valve, are no longer necess-ary:

– the use of restrictors

– the use of limit switches

– the use of mechanical end position cushioning(shock absorbers)

– the maintenance of fixed stops.

Compared with impact-limited drives with pulse-valve control,the SPC11 permits:

– higher machine cycle times

– less vibration of the system

– lower maintenance costs.



Components

In order to implement fast positioning with electronicallyclosed-loop controlled end position cushioning, you willrequire the following components:

– the Soft Stop SPC11

– a proportional directional control valve type MPYE-5-...

– a service unit with a 5 μm filter, without lubricator

– a permitted path measuring system (external orintegrated with the drive)

– a drive, if possible with mechanical guide

– if possible, two fixed stops (depending on the drive used)

– a 24 V DC power supply

– if necessary, components for a pneumatic emergency stopcircuit

– possible components for additional pneumatic circuits(see chapter 3.2.1).



1.2 Method of operation

Tasks of the SPC11 The SPC11 takes over the following tasks:

– It ascertains characteristic system values of theconnected components

– It saves the desired end positions and intermediatepositions

– It specifies the end positions and intermediate positions

– It compares the nominal and actual positions and controlspositioning by appropriate actuation of the proportionaldirectional control valve (status control).

Method of operation The SPC11, the valve, the drive and the measuring systemare connected together to form a closed-loop control circuit.In this closed-loop control circuit, the position of the move-able mass represents the control variable. This control cir-cuit is therefore also called positioning control.

In the following text, the term “moveable mass” also refers topiston, slide and flange shaft.

The following diagram shows the basic layout of a positioningcontrol circuit with the SPC11.

Fig. 1/2: Positioning control circuit with pneumatic components

The measuring system registers continuously the position ofthe moveable mass and transmits this in the form of an elec-tric signal to the SPC11. The SPC11 compares the currentposition with the target position (the “taught” end positionsPo.1 and Po.2 or the intermediate positions Po.3 and Po.4)and calculates from this value the positioning signal for theproportional directional control valve.

The proportional directional control valve controls the driveby pressurising one cylinder chamber and exhausting theother. The flow is blocked in the valve slide mid-position.

S Use a microfilter if you cannot avoid slight oil mist fromthe compressed air supply.

3. Installation


Compressed air reservoir (3 )

If the positioning behaviour does not conform to your require-ments, and if you ascertain fluctuations in pressure of over1 bar at the measuring point, then proceed as follows:

S Fit a compressed air reservoir (e.g. type VZS-...-B) be-tween the service unit and the proportional directionalcontrol valve.

In this way you can reduce fluctuations in pressure duringoperation. You can compensate for slight excesses in thepermitted pressure by using supply tubing with a largerdiameter.

Reservoir volume:

The reservoir volume should be at least four times as large asthe volume of the drive used.

VP = 4 * VZ

VP = buffer volumeVZ = cylinder volume (linear drive: VZ = r2 * ð* LZ)LZ = cylinder stroke length

3. Installation


Compressed air tubing and screw connectors (4 )

S Use only straight screw connectors. If angled connectorscannot be avoided, use plug connectors from the QuickStar series.

S Cut compressed air tubing and hoses to the required size,as specified in the manual for the drive used.

S Arrange the tubing between the valve (MPYE-5-...) and thedrive symmetrically.

S Use only clean compressed air tubing and connectors.Details on permitted temperatures and pressure rangesfor tubing and connectors can be found in the productscatalogue.

S Do not install restrictors in the supply lines.

S Arrange the tubing so that it does not project into thepositioning range.

For good positioning behaviour during operation, fluctuationsin pressure of max. 1 bar are permitted in front of the propor-tional directional control valve. In order to check the stabilityof the supply pressure, you can fit a pressure measuringpoint directly in front of the proportional directional controlvalve.

3. Installation


Proportional directional control valve (5 )

Arrange the tubing between the valve (MPYE-5-...) and thedrive symmetrically.

Recommendation for linear drives and drives with piston rod:tubing length = cylinder length.

The diagram below shows as an example the tubing of acylinder with an MPYE-5-... when an SPC11 is used.

Fit the valve in accordance with the operating instructionssupplied with the valve.

3. Installation


S If the proportional directional control valve is to be usedin an environment subjected to heavy electrical interfer-ence, it should be insulated from the mounting surface.

Fitting onto moving parts

S If fitted to moving parts, the proportional directional con-trol valve must be mounted at right-angles to the direc-tion of movement. Acceleration forces then have no influ-ence on the valve slide setting.

Reducing loud exhaust noises

S Fit larger silencers with the aid of tubing or:

S Pass the ducted exhaust into a small compressed airreservoir and exhaust this with a large silencer. Make surethat there is sufficient flow through the screw connectorsand tubing (with PUN-8 tubing length max. 1 m).

Drive (6 )

Use only the permitted combinations of drives and measuringsystems approved of by Festo for the SPC11.

The drive-valve combinations, cylinder diameters, cylinderlengths and mass loads permitted for the drive used can befound in the “Drive-Specific Supplement” manual.

Connect the drive, guide, measuring system and the load freeof play in the direction of movement and flush with eachother.

If necessary, provide a sufficiently large supply of energy inorder to minimise the effects of transverse forces on the posi-tioning behaviour.

Observe the maintenance intervals specified in the operatinginstructions for the drive (see operating instructions for thecylinder/drive or the guide).

3. Installation


Path measuring system (7 )

See also “Drive-Specific Supplement”.

S Fit the measuring system and the drive symmetrically sothat the centre of the usable measuring system strokecorresponds to the centre of the complete cylinder stroke.

With type MLO-POT-...-TLF:

The remaining path of the measuring system slide must beidentical in the cylinder end positions on both sides.

3.2.1 Additional pneumatic circuits

You may require additional pneumatic circuits in order toattain a particular status for the system in certain applica-tions. Choose between the following alternatives based onthe design and operating characteristics of your system:

– drive pressureless

– drive clamped

– drive moves while throttled to the left or right endposition.

Please noteIf the operating voltage supply for the SPC11 is switchedoff, the proportional directional control valve type MPYE-...will move to the mid-position. Due to the asymmetricalvoltage-pressure curve of the proportional directional con-trol valve when the supply pressure is switched on, theslide can move slowly into one of the end positions.

4.1 General instructions on commissioning

This chapter describes parameterising and commissioningwith the aid of the three buttons on the SPC11. A 1-signal atthe Remote input (I8) blocks the SPC11 buttons. Button func-tions can then be called up via the digital inputs (I5...7).Detailed information on this can be found in appendix A.

WarningDuring commissioning and during operation the moveablemass is moved at the highest possible acceleration andspeed. Make sure that:

– Nobody can place his/her hand in the positioning rangeof the moveable mass, unless the compressed air supplyis switched off.

– The complete positioning range is free collisioncontours.

WarningIncorrectly set parameters can damage the fixed stops andthe drive.

Be very careful when setting the parameters.

Offset axis zero point (r)[mm]

For a good positioning behaviour, the SPC11 must know thepositioning range used by the drive. The offset axis zeropoint specifies the offset between the end position P.01 andthe axis zero point. With an offset of 0 cm, the end positionP.01 lies in the axis zero point.

Remarks on reference travel

With incremental path measuring systems, the measurementvariable refers to a reference point and is determined bycounting equally large measurement steps (increments). Therelationship between measurement variable and current posi-tion is created through the reference travel.

Referencing in the teachprocedure

In the teach procedure (see also section 4.3.1), the endpositions P.01 and P.02 are approached. This creates therelationship between measurement variable and currentposition. Reference travel is not necessary.

Reference travel afterPOWER ON

After the SPC11 operating voltage is switched on again, therelationship between measurement variable and currentposition is lost. Reference travel into the end positions P.01or P.02 is necessary (see also section 4.4).

4.2.3 Parameter o (options)

With this parameter, you can change the signal behaviour ofthe SPC11 and switch off certain standard functions (fromVersion 1.41).

Please noteThe factory setting (o-parameter = 0) means:

– No option selected. Standard behaviour active.

Standard behaviour at factory setting (o-parameter = 0):

– Output O5 supplies Error signal

– Positioning time monitoring (10 s) active

– Constant adaptation active

– Soft end position behaviour active

– Input I4 can be used for the positioning order to thetaught intermediate position P.04

In the factory setting (o-parameter = 0), the above behaviouris identical to the previous version (there no options wereselectable).

Internally, the decimal value is interpreted as binary. A spe-cific option is assigned to each bit (see following table). Onlyallowable option combinations can be set. This results in apossible value range of 00 to 79 for the o-parameter.

Use I4 for Stop signal – instead of Move signal (to P.04).Permits stopping the drive – even during the teach pro-cedure. Output O4 supplies a 1-signal. One of the followingoptions can be selected:– Stop without return travel (bit 5): With the 0 signal at

input I4, the drive stops with the brake incline deter-mined in the teach procedure. 2) 3)

– Stop with return travel (bit 6): With a 0-signal at input I4,the current position is taken over as the Stop positionafter an internally required signal processing time. Thedrive is braked with maximum power and travelled backto the Stop position. 2)

For instructions on stopping, see section 4.2.4.

4.2.5 Set parameters

At the factory, all the parameters are zero (status at delivery).When the power supply is switched on, the SPC11 in this caseexpects entry of the parameters. In preparation for commis-sioning, the parameters can be set “in the office” withoutsetting up the drive. This simplifies the commissioning oflarge series in production.

Set the parameters without drive (in the office) as follows:

WarningIncorrectly set parameters can damage the fixed stops andthe drive.

4.2.6 Changing parameters

Please noteThe option parameter o can be changed without a newteach procedure being necessary. After the parameters A,C, S, L or r are changed, the teach procedure must be per-formed again.

If necessary, the set parameters can be modified, e.g. in orderto correct entry errors or to optimise positioning behaviour.This can be carried out in one of the following ways:

Possibilities Description

Activate modificationmode

In this mode the set parameter values areretained and can be modified or trans-ferred. Taught intermediate positions areretained.

Create status as atdelivery

All parameter values are then set to 0.Taught intermediate positions are deleted.

Activate modification mode

Condition The measuring system must be connected. There must be a0-signal at input Remote (I8). The drive must be at a stand-still.

CautionWhen the modification mode is activated, the valve slideassumes the mid-position. During positioning the masscan therefore move uncushioned into an end position.

Make sure that the drive is standing still before you acti-vate the modification mode.

4. Commissioning


Use the buttons as follows to activate the modification mode:

1. Make sure that the drive is standing still.

2. Press all three buttons on the SPC11 at the same time.

The display shows the letter A (Amplification stage) andthe stage set (here 02).

(A.02)

If you have activated the modification mode by mistake, youcan abort the procedure by switching off the power supply. Ifyou have already carried out the teach procedure, you can inthis way avoid the need to carry out this procedure again.

With the +/- buttons, you can modify the parameter displayedand transfer it with Enter.

When you change the parameters A, C, S, L or r:When the last parameter has been transferred, the SPC11then indicates readiness to carry out the teach procedure(t flashes).

Create status as at delivery

Condition The measuring system must not be connected. There mustbe a 0-signal at input Remote (I8). The compressed air sup-ply must be switched off.

Use the buttons as follows to create the status as at delivery:

1. Switch off the compressed air and the power supplies.

2. Disconnect the measuring system cable from themeasuring system.

4.3 Commissioning procedure

WarningFaults in the system structure and incorrect parameterscan cause the slide to move to an end position uncu-shioned. The fixed stop or the drive may then be de-stroyed. You must observe the following instructions inorder to prevent such collisions.

– The SPC11 “learns” the location of the end positions(cylinder end positions or fixed stop positions) by meansof the teach procedure. The teach procedure must becarried out during the first commissioning and alwayswhen the fixed stops have been adjusted or when compo-nents and tubing have been replaced.

– During the teach procedure the SPC-11 can recognisefaulty drive tubing or incorrectly set parameters. Theteach procedure must therefore be carried out again if thetubing is disconnected and then reconnected, or if theparameters A, C, S, L or r are modified.

– Make sure that the maximum permitted mass load isobserved during operation.

Recommendation:Place appropriate warning signs on your system.

4. Commissioning


4.3.1 Preparations for the teach procedure

Teach procedure During the teach procedure movement is made at firstcyclically and slowly to the end positions P.01 and P.02. Inthis way the SPC-11 learns the mechanical end positions andsome characteristic system values such as friction andhysteresis. The SPC11 saves these values in the integratedEEPROM.

In order to check the set parameters for plausibility, themoveable mass is first brought dynamically into the centre ofthe positioning stroke used and then moved to just in front ofend position P.01.

Please noteWhen an incremental path measuring system is used(e.g. with type DNCI-...-...): During the teach procedure,movement is made to the end positions P.01 and P.02. Thiscreates the relationship between measurement variableand current position. Reference travel is not necessary.

The teach procedure is concluded when the moveable mass ispressed against end position P.01 and the output O1 suppliesa 1-signal.

Before commissioning can be undertaken, the pneumaticdrive must be ready for operation. The teach procedureshould be carried out with maximum permitted mass load.During the teach procedure there must be a 0-signal at inputsP.01 to P.04.

Proceed as follows in order to prepare the teach procedure:

1. Check the complete system structure, especially the drivetubing (see chapter 3). Special specifications for yourdrive can be found in the “Drive-Specific Supplement”.

2. Check the electrical circuitry.

4. Commissioning


3. If fixed stops are used:Set the fixed stops accurately in the desired end posi-tions. The positioning stroke permitted for the drive usedcan be found in the “Drive-Specific Supplement”.

4. Check whether the parameters have already beencorrectly set in pre-commissioning.

The permitted values of the parameters A, C, and S for thedrive you are using can be found in the appropriateaxis-specific supplement. The currently set values will beshown briefly when the operating voltage is switched on(see also Fig. 4/4).

If the SPC11 is in the status at delivery:

When the operating voltage is switched on, the SPC11 waitsfor the amplification stage (A) to be entered.

S In this case, set the parameters as described insection 4.2.5.

If the parameters have already been set:

When the operating voltage is switched on, the SPC11 showsbriefly the set parameters one after the other, so that they canbe checked. The SPC11 then indicates readiness to carry outthe teach procedure (t flashes).

(t flashes)

The teach procedure can now be started (see sections 4.3.2).

4. Commissioning


4.3.2 Start the teach procedure

Condition There must be a 0-signal at inputs I1...4. The parametersmust be set correctly. The maximum mass load and, if appli-cable, the fixed stops must be fitted correctly. To be able tostart the teach procedure with the buttons, a 0-signal mustbe present at the Remote input (I8).

WarningIn order to avoid damage caused by uncushionedmovement into the end positions, proceed as follows:

– with the first commissioning

– when the fixed stops have been adjusted

– after changing the parameters A, C, S, L, r

– or after replacing components or tubing.

1. Make sure that:• the compressed air supply and the operating voltage of

the SPC11 are switched off• the above-mentioned prerequisites are fulfilled.

2. Switch on the operating voltage for the SPC11. The SPC11will then show briefly the version number of the firmware.The set parameters are then shown, so that they can bechecked.

3. Now switch on the compressed air supply (5 to 7 bar).As the valve slide assumes the intermediate position, themoveable load can move slowly into one of the end posi-tions due to the asymmetrical voltage-pressure curve ofthe proportional directional control valve.

4. Commissioning


CautionDuring the teach procedure, the moveable mass moves atfirst slowly, then at the highest possible acceleration andspeed. Make sure that:


– The complete positioning range is free collisioncontours.

4. If teaching has not yet taken place, the SPC11 indicatesreadiness to carry out the teach procedure (t flashes).

Then proceed as described under 5.

If teaching has already taken place, the moveable massstands controlled in a taught position (P.01...P.04) or inany (P..) position. Proceed as follows:

S Hold the Enter/Teach button pressed down for at least2 seconds. The SPC11 then indicates readiness tocarry out the teach procedure (t flashes).

5. Hold the Enter/Teach button down at least 2 seconds inorder to start the teach procedure.The SPC11 then carries out the teach procedure. Themoveable mass moves at first slowly, then dynamically.The display shows the following:

The dots flash at the same rate.

The teach procedure can last several minutes, depending onthe drive used. It is concluded when the drive is at end posi-tion P.01. The display shows the following:

4. Commissioning


The O1 output supplies a 1-signal The drive is now ready foroperation.

When the teach procedure is concluded, the SPC11 knowsthe locations of the mechanical end positions (P.01...P.02).You can now teach manually the intermediate positions(P.03...P.04) or trigger a positioning task to the end positions(P.01...P.02).

4. Commissioning


4.3.3 Teach the intermediate positions

The SPC11 permits fast movement into up to two selectableintermediate positions. The desired intermediate positionsare “learnt” by manual movement or by shifting the moveablemass and then saving. The “learnt” intermediate positionscan be approached during operation.

The intermediate positions can also be used as sensor posi-tions, as the relevant output (O3...O4) supplies a 1-signal for50 ms when the intermediate positions are travelled over(see section 4.4.5).

Condition The drive must be ready for operation. There must be a0-signal at inputs I1...4. In the procedure using the buttonson the SPC11, a 0-signal must be present at the Remoteinput (I8). The supply pressure must be switched on or off,depending on the variant.

Variants Procedure

The supply pressure isswitched off

The moveable mass can brought into thedesired position very accurately by handduring the teach procedure.

The supply pressure isswitched on

The mass can be moved manually. Veryaccurate positioning can, under certaincircumstances, be difficult and may take aconsiderable amount of time.

The following explains how to teach the intermediate posi-tions when the supply pressure is switched on. If you wish toteach the intermediate positions with the supply pressureswitched off, you must proceed in exactly the same manner.However, the mass will not start moving automatically whenthe button is pressed { or }, but must be brought into thedesired intermediate position by hand. The button { or }must still be pressed at the appropriate position.

4. Commissioning


In order to teach an intermediate position with the supplypressure switched on, proceed as follows:

1. Briefly press the button { or } . The teachable positionnumber (e.g. 3) will then flash.

The position number flashes.

2. If you do not wish to teach the intermediate positionshown, press briefly the ESC button. The process will thenbe interrupted. Then repeat step 1. The next teachableposition number will then flash.

Please noteThe following function will cause the drive to be set inmotion. Make sure that:


– The positioning range is free collision contours.

3. If you wish to teach the intermediate position shown, holdthe button { or } pressed down for as long as is re-quired to move the mass. The mass will then move in theappropriate direction.

4. Release the button when the mass is to stop moving. Themass now stands controlled in the current position.

5. Repeat steps 3 and 4 until the moveable mass reachesthe desired position.

The position number flashes.

6. When the moveable mass has reached the desired posi-tion, confirm with Enter (> 2 s ), in order to save the posi-tion. The current position will then be saved as the inter-mediate position. The appropriate output (O3 or O4)supplies a 1-signal.

4. Commissioning


No flashing.

7. If you wish to teach the next intermediate position, repeatthe steps listed as from step 1.

Repetition accuracy The repetition accuracy when moving to the intermediatepositions depends on the type of drive and on the length ofthe measuring system.

Detailed dimensions for repetition accuracy with the driveyou are using can be found in the drive-specific supplement.

Please noteObserve the following instructions in order to achieve goodpositioning behaviour and the repetition accuracy speci-fied.

– The distance between the intermediate position and thedrive end position must be at least 10 % of the completecylinder stroke length or of the complete rotary angle, inorder to provide a sufficient compressed air cushion.

– Positioning paths between taught positions should not beless than 3 % of the complete cylinder stroke length or ofthe complete rotary angle.With linear drives and cylinders the positioning pathsshould be at least 20 mm.

– If the intermediate positions P.03 and P.04 lie at the samepoint and if movement is made to one of the intermediatepositions (e.g. to P.03), only the output corresponding tothe order (e.g. O3) will be set when the intermediate posi-tion is reached. The output bit of the other intermediateposition will be set for 50 ms only if the position is tra-velled over (overswing) (sensor function).

4.3.4 Conclude teach procedure

Adaptation The positioning behaviour is monitored continuously duringoperation. Internal characteristic values are adapted here tothe actual state of the drive, e.g. in order to compensate forwear etc. during the service period.

After commissioning, the positioning behaviour improves byadaptation automatically after approximately 20 to 30 strokes.Therefore, after teaching the end positions and intermediatepositions, always allow 20 to 30 positioning cycles to becarried out.

4.3.5 Carry out teach procedure again

When the SPC11 is ready to operate, the teach procedure canbe started again, e.g. with the aid of the Teach button.

Condition There must be a 0-signal at inputs I1...4. The parametersmust be set correctly. The maximum mass load and, if appli-cable, the fixed stops must be fitted correctly. To be able tostart the teach procedure with the buttons, a 0-signal mustbe present at the Remote input (I8).

The SPC11 then indicates readiness to carry out the teachprocedure (t flashes). The procedure can then be discon-tinued if the power supply is switched off. If the Teach buttonis pressed again (for at least 2 seconds), the teach procedurewill be started (see section 4.3.2).

If the end positions are taught again, the adaptation valueswill be deleted. Intermediate positions already “taught” areretained.

4. Commissioning


Please noteIf, after you have taught the end positions again, the previ-ously taught intermediate positions (P.03 and P.04) now lieoutside the positioning range, positioning commands tomove to the intermediate positions will be acknowledgedwith error E14. As soon as the intermediate positions lieagain in the permitted positioning range by adjustment ofthe end stops and teaching again of the end positions,positioning commands to move to the intermediate posi-tions will be carried out again.

4.4 Instructions on operation

WarningDamage may occur if maximum permitted limits, such asmass loads, mass moments of inertia, swivel frequenciesetc. are exceeded. Make sure that the maximum specifiedlimits of the drive used are observed (see operating in-structions for the relevant drive).

WarningIn order to avoid damage due to uncushioned movementinto the end positions:

S Always carry out the teach procedure again after adjust-ing the fixed stops or when components and tubing havebeen replaced.

S Observe the permitted mass load.

WarningIn order to avoid undesired movements of the actuators,always proceed as follows:

Switching on

S Always switch on first the operating voltage supply andthen the compressed air supply.

Switching off

S Switch off the operating voltage supply and the com-pressed air supply at the same time or in the followingsequence:1. compressed air supply2. operating voltage.

4. Commissioning


Reference travel afterPOWER ON

Only for incremental path measuring systems:After the SPC11 operating voltage is switched on again, therelationship between measurement variable and currentposition is lost. For that reason, you must always carry outreference travel after switching on again. Reference travelcan take place either in the end position P.01 or the endposition P.02.

Starting reference travel Reference travel is started after POWER ON through apositioning task to P.01 or P.02.

Other positioning tasks are not permitted after POWER ONand result in the error E18 “reference travel”.

Process of referencetravel

If the drive is already in the desired end position when refer-ence travel is started:A movement toward the end position is impossible. To checkwhether compressed air supply is lacking or the drive isalready in the end position, pressure is added briefly in theopposite direction.

Please noteHere the drive carries out a short compensating movementin the opposite direction.

If the drive is not yet in the desired end position when refer-ence travel is started:The drive moves slowly toward the end position.

During the reference travel, the message “rEF” is displayed.Reference travel is concluded when the moveable mass ispressed against the corresponding end position (P.01 or P.02)and the assigned output (O1 or O2) supplies a 1-signal.

4. Commissioning


Positioning orders A positioning order remains permanently stored if the powersupply is switched on. If the power supply is switched offand then on again, the positioning order (P.01...P.04) at in-puts I1...I4 will then be processed.

If there is no positioning order when the power supply isswitched on and if the moveable mass is not at one of the endpositions, the valve slide will remain in the electrically cen-tered intermediate position. Due to the asymmetrical voltage-pressure curve of the proportional directional control valve,the slide can now move slowly into one of the end positions.

4.4.3 The first positioning task

During the first positioning task the SPC11 checks whetherthe mass moves in the desired direction. If the mass moves inthe wrong direction, the SPC11 will diagnose incorrectly con-nected tubing in the system and display error E12 (incorrectdirection of movement). The SPC11 then reacts as follows:

– The valve slide of the proportional directional controlvalve will then be brought into the intermediate position(flow blocked).

– The ERROR output supplies a 1-signal.

– No new positioning task will be accepted.

This safety function helps prevent damage being caused byincorrect connections.

In the case of incorrectly connected tubing in the system:

S Switch off the operating voltage and correct the tubing.

If the moveable mass is already in one of the end positionswhen the operating voltage is switched on, a positioning taskinto this end position will be generated and the mass will bepressed against the end position. If the drive moves out ofthe end position instead of remaining in that end position, theSPC11 will also diagnose incorrectly connected tubing in thesystem and will display an error. The fault may be due to oneof the following causes:

– the compressed air supply is still switched off. the drivehas been moved manually or moved from the end positionby external forces, or it has moved itself (e.g. when fittedin a vertical position).

– the drive moves briefly out of the end position becausethe system has been pressurised too quickly (asymmetri-cal pressure build-up in the cylinder chambers).

4. Commissioning


In order to avoid such causes, proceed as follows:

S Pressurise the complete system slowly (e.g. by using thesafety start-up valve type HEL-... or HEM-...). No unex-pected movements of the actuators will then occur.

S Make sure that the moveable mass cannot move itself orbe moved manually (e.g. by means of a clamping unit) outof the end position when the operating voltage isswitched on.

4. Commissioning


4.4.4 Controlling the SPC11

You can move the mass into the saved end positions or inter-mediate positions with the command inputs P.01...P.04.When an end position is reached, the moveable mass will bepressed against the stop with a pressure equal at maximumto the operating pressure. When an intermediate position isreached, the moveable mass stands controlled in that posi-tion.

A 1-signal at the remote input deactivates the operatingbuttons and activates the corresponding remote inputs(pins 2...4). This makes it possible to manually travel overexternal operating buttons or a higher-order PLC, for example(Pin assignment, see section 3.3.2).

Please noteA position task or stop procedure can be interrupted atany time and replaced by a new task.

Manual movement

Condition The drive must be ready for operation. There must be a0-signal at inputs I1...4. In the procedure using the key-board, a 0-signal must be present at the input I8 (remote).

The moveable mass can be moved manually with the buttons{ or }.

Button Description

{/- Reduce the position value (the mass moves slowly inthe direction of the measuring system zero point)

+/} Increase the position value (the mass moves slowlyaway from the measuring system zero point)

In order to move the mass manually:

S Hold the button { or } pressed down for as long as isrequired to move the mass.

S Release the button in order to stop the mass.

The position number flashes to indicate that the current posi-tion can be saved as the intermediate position if the Enterbutton is pressed (see section 4.3.3).

4. Commissioning


4.4.5 Use the taught intermediate position as the sensor position

The taught intermediate positions can also be used as sensorpositions, as the relevant output (O3...O4) supplies a 1-signalfor 50 ms if the intermediate positions are overrun.

Example 1: Change of direction

Please noteIf the SPC11 is to be controlled directly by means of the“sensor signal”, note that:

– the distance between the taught intermediate positionand the mechanical end position must be of sufficientlength, as the braking process is not started until thesignal is recognised.

A premature change of direction can be implemented with theaid of a taught intermediate position. The relevant output bit(O3...4) of the SPC11 supplies a 1-signal for 50 ms when themoveable mass has traversed the relevant path. The move-able mass is then moved back to the end position by meansof an input signal.

If there are no more faults, Output O5 will supply the desiredsignal again with the o-parameter (for Error 0-signal, forReady 1-signal).



5.4 Optimising the positioning behaviour

After the “teach” procedure the positioning behaviour isautomatically optimised in the first 20 to 30 strokes by meansof internal adaptation. If the quality of the positioning behav-iour still does not fulfil expectations, proceed as follows:

– Check the parameters A, C, and S (see “Drive-SpecificSupplement” for the drive used).

– Check whether the installation of the pneumatic compo-nents fulfils the demands listed in section 3.2. Make sureespecially that the supply pressure is stable, that the tub-ing is of the correct length and diameter and that the cor-rect screw connectors are used.

– Check the set options (o-parameters). The following op-tions influence positioning behaviour (see section 4.2.3):

– constant adaptation on/off

– soft end position behaviour on/off.

If, however, the moveable mass still moves into the end posi-tions with too hard an impact, or brakes too heavily beforereaching the end position, you can optimise the positioningbehaviour by increasing or reducing the cushioning leveland/or the amplification level.

Control parameter stage Display

Amplification stage

Cushioning stage



WarningIncorrect parameters can damage the fixed stops and thedrive.


When parameters are modified, the saved end positions andadaptation values are deleted for safety reasons. Therefore,the “teach” procedure must then be carried out again. Inter-mediate positions already “taught” are retained.

All parameters are set to 0 at the factory. Further informationon the parameters see “Drive-Specific Supplement” for thedrive used.

Cushioning stage The cushioning stage serves to optimise the approachbehaviour when moving to the end positions (lower stage =less cushioning).

Setting Description

Too high The positioning procedure is heavily cushioned.The positioning time is extended.

Too low Leads to heavy overswing and, as a result, to hardstriking of the fixed stops.

Optimal The braking phase (counter pressurisation) isstarted early enough. Less shaking whenmoving toend positions.

Amplification stage The amplification stage should not normally be modified(lower stage = less amplification).



Procedure for optimising

NoteIf, after you have taught the end positions again, the previ-ously taught intermediate positions (P.03 and P.04) now lieoutside the positioning range, positioning commands tomove to the intermediate positions will be ignored. Assoon as the intermediate positions lie once again in thepermitted positioning range, as a result of adjustment ofthe end stops and re-teaching of the end positions, posi-tioning commands to move to the intermediate positionswill be carried out again.

Condition There must be a 0-signal at inputs I1...4. The maximummass load and, if applicable, the fixed stops must be fittedcorrectly.

1. Ascertain first the cushioning stage which isrecommended for the components you are using(see “Drive-Specific Supplement”).

2. Make sure that the drive is standing still.

CautionWhen the modification mode is activated, the valve slideassumes the mid-position. During positioning the masscan therefore move uncushioned into an end position.

Make sure that the drive is standing still before youactivate the modification mode.

3. In order to activate the modification mode, press all threebuttons on the SPC11 at the same time. The modificationmode will then be activated. The SPC11 shows the ampli-fication stage set, e.g.:

(A.02)



4. With the buttons +/- you can increase or reduce the valueby one stage, in accordance with the positioning char-acteristics of the drive (see axis-specific supplement).Hold the Enter key pressed down for at least 2 seconds(> 2 s) in order to accept the value. The cushioning stagewill then be shown.

(C.04)

5. With the buttons +/- you can increase or reduce the valueby one stage, in accordance with the positioning char-acteristics of the drive (see axis-specific supplement).Hold the Enter key pressed down for at least 2 seconds(> 2 s) in order to accept the value. The system parameterwill then be shown.

(S.01)

6. Check and, if necessary, correct the current setting.Hold the Enter key pressed down for at least 2 seconds(> 2 s) in order to accept the value. The next parameterwill then be shown.

7. Check and correct the other parameters:

– with type SPC11-INC:– nominal stroke length (L)– offset axis zero point (r)

– with all types:– o-parameter (options).

When the o-parameter is confirmed, the SPC11 displaysreadiness to carry out the teach procedure.

The t flashes.



Please noteDuring the teach procedure, the moveable mass moves atfirst slowly, then at the highest possible acceleration andspeed. Make sure that:


– The complete positioning range is free of any objects.

8. If there is a 0-signal at the Remote input:Hold the Teach button pressed down for at least2 seconds.If there is a 1-signal at the Remote input:Apply a 1-signal to the Teach input for at least 2 seconds.

The SPC11 then carries out the teach procedure. Themoveable mass moves at first slowly, then dynamically.The display shows the following:

The dots flash at the same rate.

The teach procedure can last several minutes, depending onthe drive used. It is concluded when the drive is at end posi-tion P.01. The display shows the following:

(P.01)

The O1 output supplies a 1-signal The drive is now ready foroperation. The intermediate positions P.03 and P.04 can betaught.

9. Check the positioning behaviour. Repeat points 2 to 8 ifthe positioning behaviour does not yet fulfil your expecta-tions.



In order to influence the positioning times

S Increase or reduce the supply pressure within thepermitted range.

S Install exhaust restrictors in the exhaust lines of theproportional directional control valve.

NoteMake sure that the exhaust-air throttles are completelyopened during the teach procedure.

If fluctuations in pressure of over 1 bar occur in front of theproportional directional control valve, install a compressedair reservoir (see chapter 3). Please observe the general in-stallation instructions!

A.1 The SPC11 remote inputs

A 1-signal at the Remote input deactivates the SPC11 buttons.The button functions can then be called up via the digitalinputs (I5...7). This permits start-up via external operatingbuttons or a higher-order PLC/IPC.

Input Function Description

I7 {/- With position change:A 1-signal (min. 20 ms) at this input continuously reduces theposition value as long as the 1-signal is present (drives movestoward the measuring system zero point).With parameter change:A 1-signal (min. 20 ms) at this input reduces the parametervalue by one. 1)

I6 Enter/Teach(> 2 s)

Esc (< 1 s)

A 1-signal at this input (longer than 2 seconds) confirms theparameter value or starts the teach procedure.

A short 1-signal (< 1s ) breaks off the procedure.

I5 +/} With position change:A 1-signal (min. 20 ms) at this input continuously increasesthe position value as long as the 1-signal is present (drivesmoves away from the measuring system zero point).With parameter change:A 1-signal (min. 20 ms) at this input increases the parametervalue by one. 1)

1) Continuous change of parameter values is only possible via the SPC11 buttons.



A.2 Remarks on start-up via digital inputs/outputs

NoteWith start-up via digital inputs, the same requirementsmust be met as with start up via the buttons of the SPC11(see chapter 4).

Setting the parameters using PLC/IPC

The SPC11 parameters can be set via the digital I/Os, such aswith external operating buttons, or by PLC/IPC.

The process of start up via digital I/Os does not differ fromstart up via the buttons on the SPC11. A continuous changeof parameter values is only possible via the SPC11 buttons(see chapter 4).

NoteWhen changing parameters, the current parameter valuesare presented in the display on the SPC11. There is noacknowledgement to the PLC/IPC.

How the parameters can still be set by PLC/IPC is shown inthe following flow diagram (see Fig. A/1) and the time-de-pendency diagrams contained in the following sections.
