S Use fastening elements which will permanently resist theacceleration forces.

S Avoid installing restrictors or non−return valves in the sup�ply line.

S Connect the drive and the load in the direction of move�ment free of play.

S For earthing, connect the earthing connection of theDSMI−... and the earth connection of the SPC11 with lowimpedance with an earthing band (short cable with largecross−sectional area; see Fig.�1/1).



Fixed stops ( 7 )

If the DSMI−... is operated in conjunction with the SPC11,fixed stops will be required. By means of the fixed stops, theend positions can be set as desired. Notes on setting thefixed stops can be found in the operating instructions for theDSMI−... .

Please noteDuring the teach procedure, a work load is pressed againstthe fixed stops at a pressure up to the level of the operat�ing pressure. Make sure that the fixed stops can withstandthis pressure, in order that the SPC11 can ascertain exactlythe end positions during the teach procedure.

Please noteIn order to avoid damage caused by uncushioned move�ment into the end positions, the teach procedure must becarried out again after the fixed stops have been adjustedand components and tubing have been replaced.



Mass load

S Fit the mass load free of play.

S Avoid mass loads with unfavourable natural vibrationfeatures.

Please noteNatural vibrations of the mass load can cause faults.Mount the mass load so that vibration is kept to a mini�mum. Avoid mass loads on long flexible lever arms.

2.1 Parameters of the SPC11

WarningIncorrectly set parameters can damage the fixed stops andthe drive.Be very careful when setting the parameters.

The SPC11 must be familiar with certain conditions of use.These conditions of use are described by the following threeparameters, which must be entered directly on the SPC11:

Parameters Display Manual

Amplification stage Influences the accelerationbehaviour of the drive.

Cushioning stage Influences the retracting be�haviour when moving to theend positions and intermedi�ate positions.

System parameters Characteristic value for thedesign of the drive.

These amplification and cushioning stages are matchedexactly to certain valve−drive combinations and mass loadsfor horizontal operation.

You can set the amplification and cushioning stages valid foryour application, as well as the system parameters, with thekeys on the SPC11 (see system manual).



Specifications for setting the parameters

In order to set the parameters, you will require the followingspecifications:

� the diameter of the drive (see type plate on the driveused)

� the valve type (see type plate on proportional directionalcontrol valve used)

� the maximum mass load with which the drive may beloaded.

Mass moment of inertia

Festo supports you in ascertaining the mass moment of iner�tia with the MTM calculation program (Internet:http://www.festo.com). This program serves for calculatingthe mass moments of inertia of 2nd. grade for various basicbodies and Festo standard parts (e.g. plug−on flange forDSMI−...).

Positioning with different mass moments of insertia:

� Positioning with a mass moment of inertia up to 30 % lessis usually no problem. Further reduction of the mass mo�ment of inertia can lead to worse positioning behaviourand make optimization necessary (see system manual).

� If necessary, place a basic load on the drive, in order toset a higher mass moment of inertia. Positioning can thenbe made with a greater difference in the mass moment ofinsertia.

� Always set the amplification and cushioning stages for themaximum mass moment of inertia used.



2.2 Setting parameters

WarningIncorrectly set parameters can damage the fixed stops andthe drive.Always select the amplification and cushioning stages forthe maximum mass moment of inertia.If in doubt, set firstthe amplification and cushioning stages for the lager massmoment of inertia.

The swivel times specified in section 2.3 as well as optimumsystem behavour can only be achieved if the installation in�structions described in the previous section are observed.The resulting swivel times depend on the swivel angleactually used and can vary depending on the direction ofswivel.

Further instructions on the amplification and cushioningstages can be found in the system manual.

Set the parameters as follows:

1. Use the tables in section 2.3 to ascertain the parametersvalid for your application.

2. Then set the parameters. Proceed here as described inthe chapter �Commissioning" in the system manual (type P.BE−SPC11−SYS...).

The following diagram explains the tables:
