Safety note

Protection against dangerous movements

WarningHigh acceleration forces at the connected actuators!Unexpected motion can cause collisions and severeinjuries.

Dangerous movements can occur through faultycontrolling of connected actuators, e.g. via:

� unsafe or faulty circuitry or cabling,

� faulty operation of the components,

� faults in the measured value and signal generators,

� faulty or non−EMC−compliant components,

� faults in the higher−order control system.

· Before carrying out assembly, installation andmaintenance work, always switch off the power supplyand compressed air supply.Always make sure that the compressed air supply andpower supply are switched off and locked beforeworking in the machine area.

· Make sure that no persons are in the operating range ofthe drives or any other connected actuators.

· Simply switching off the compressed air supply or loadvoltage are not suitable locking procedures. In the eventof a fault, this could lead to unintentional movement ofthe drive.

· Do not switch on the compressed air supply until thesystem is correctly installed and parameterised.

· If used in safety relevant applications, additionalmeasures are necessary, e.g. in Europe the standardslisted under the EU machine guidelines must beobserved. Without additional measures in accordancewith statutory minimum requirements, the product is notsuitable for use in safety−related sections of controlsystems.

2.1 General notes on fitting and installation

Information about fitting the CPX terminal can be found in theCPX system manual (P.BE−CPX−SYS−...).

NoteThe use of components that have not been approved foroperation with the CMIX may lead to malfunctions.

Use only the special matching components from Festo forsetting up and wiring the system.

When fitting the pneumatic components, observe also thenotes on fitting in the operating instructions supplied and thenotes on installation in this chapter.Only then can you guarantee faultless operation.



2.2 Fitting and removing the CMIX

The CMIX is mounted in an interlinking block (see alsosection�2.6) of the CPX terminal, see Fig.�2/1.

Note· Always switch off the power supply before fitting orremoving CPX modules.

NoteThe CMIX contains electrostatically sensitive components.

· Therefore, do not touch any components.

· Observe the handling specifications for electrostaticallysensitive components.

Removal Remove the CMIX as follows:

1. Loosen the four screws of the CMIX with a T10 TORXscrewdriver.

2. Pull the CMIX carefully and without tilting away from thepower rails of the interlinking block.

Fig.�2/1: Removal/fitting of the CMIX



Fitting Fit the CMIX as follows:

1. Place the CMIX in the interlinking block. Make sure thatthe grooves with the power contact terminals on thebottom of the CMIX lie above the power rails.

2. Push the CMIX carefully and without tilting as far aspossible into the interlinking block.

3. Tighten the screws at first only by hand. Place the screwsso that the self−cutting threads can be used.

4. Tighten the screws with a TORX screwdriver size T10 withtorque 0.9 ... 1.1 Nm.

The parameterisation is saved in the CMIX. Therefore, afterreplacing a CMIX, check the parameters and, if necessary,repeat the commissioning process; see chapter 3. Observe the instructions in section A.4.



2.3 Installation of the drive and displacement encoder

2.3.1 General requirements of the mechanics

NoteConnect the drive, guide, measuring system and load freeof play and flush with each other.

Mechanical play, such as between the cylinder’s piston rodand the mass to be moved, results in worse measurementvalues.

NoteLateral loadings produce false measuring results and maydamage the measuring system.

· Use an external guide for the working load in order toprevent transverse loadings on the drive.

· Use fastening elements which will permanently resist theacceleration forces.

NotePlease observe the notes in the operating instructions forthe axis used. Make sure that:

� the permitted lateral force,

� the permitted longitudinal force,

� the permitted mass moment of inertia,

� the maximum permitted speeds and swivel frequenciesare observed.

2.5.1 Earthing

The CMIX earthing is provided via the CPX terminal; see theCPX system description.

Observe the additional earthing measures described below,depending on the components used.

NoteFunctional faults can occur through incorrect or missingearthing.

· Connect the specified earth connections at low impe�dance (short cable with large cross−section) to the earthpotential.

Unless otherwise specified, the earthing conductors musthave:

� a cable cross−section of at least 2.5 mm2

� a cable length as short as possible (typically 20 ... 30 cm).

2.5.5 Ensuring protection class IP65

With a completely installed axis string (all plug connectionsinserted), the CMIX in the CPX terminal conforms to protec�tion class IP65.

NoteIn order to achieve protection class IP65:

· Seal unused connections with the protective capssupplied.

If the axis connection is not used, then seal this using aFLANSCHDOSE (flangesocket), S712 protective cap. You willthen achieve protection class IP65.



2.6 Power supply

The power supply for the CMIX is provided via the followingconnections on the CPX terminal (interlinking blocks withpower supply):

Interlocking block CPX−EV−S... or CPX−M−EV−S...�(VEL/SEN)

The power supply for the following is provided via theoperating voltage supply for the electronics/sensors(VEL/SEN) of the CPX terminal:

� internal electronics of the CMIX

� connected sensor interface (optional)

� connected displacement encoder.

Interlocking block CPX−EV−V...,�CPX−M−EV−V...,CPX−EV−S... or CPX−M−EV−S... (VVAL)

The CMIX does not need any load supply for the valves(VVAL) of the CPX terminal. But the voltages 0 VEL/SEN and 0 VVAL are connected by theCMIX; see section 2.6.2.

2.6.1 Determining the current consumption

Tab.�2/9 shows current consumption of the CMIX.

Current consumption of the CMIX made up of VEL/SEN ofthe CPX terminal

Typical current consumption dependent on themeasuring system

80 ... 110 mA

Maximum current consumption 110 mA

Tab.�2/9: Current consumption via VEL/SEN of theCPX�terminal



2.6.2 Power supply arrangement � formation of power zones

The modular power supply arrangement of the CPX terminalfacilitates the formation of power zones.

Observe the following:

� The CMIX connects the internal contact rails 0 VEL/SEN to 0VVAL of the CPX terminal.This means that the operating voltage for the electronics/sensors (VEL/SEN) of the CPX terminal and the CMIX loadsupply for the valves (VVAL) are thus no longer electricallyisolated.

NoteDamage to components and functional damage!

· At the module position of the CMIX, the same potential(common power unit of connection of the 0�V cables)must be supplied as the operating power supply for theelectronics/sensors (VEL/SEN) and the CPX terminal.

The CMIX always connects the 0 V supply for the elec�tronics with the 0 V supply for the valves. This must benoted when a CPX−GE−EV−V interlinking block is located tothe left of the CMIX because this can remove an intentionalvoltage isolation.

Basic information on the power supply arrangement of theCPX terminal can be found in the CPX system manual.

3.4 Commissioning with various drives/measuring systems

3.4.1 Digital measuring system (DGCI)

Immediately after switch−on, the measuring system providesthe position value. Commissioning is not necessary.

If needed, the current position can be set as zero point withthe bit REF = 1 in the control byte CCON. Confirmation takesplace via ACK = 1 in the status byte SCON. Negative valuesare output below the zero point, positive values above it.

If a zero point is established, it remains stored even afterswitching on or off.

3.4.2 Encoder (DNCI)

The incremental measuring system must be referenced afterswitch−on.

The current position is accepted as zero point (referencepoint) with setting of the bit REF in the control byte CCON.Confirmation takes place via the bits ACK = 1 and REF_OK = 0in the status byte SCON. Negative values are output belowthe zero point, positive values above it.

3. Commissioning


3.4.3 Potentiometer (MLO−..., DSMI)

At initial commissioning, the min. and max. position valuemust be set once and the effective stroke length (maximummeasurement length) written in 1/100 mm or 1/100°.

If no effective stroke length is written, 100�mm or 100° isused as default setting.

The values remain stored after switching on and off. If theexisting potentiometer is replaced by one with anotherlength, the initial commissioning must be carried out again.

Proceed as follows:

1. For definition of the min. and max. position values, themeasuring system (potentiometer) must be pushedsuccessively into the stroke−limiting mechanical stops ofthe drive or run with compressed air. To accept thepositions, the following bits are set in the control byteCCON:

Min. position: PARAM0 = 1 and PARAM1 = 0} Accept with LOAD_P = 1Max. position: PARAM0 = 0 and PARAM1 = 1} Accept with LOAD_P = 1

With the bit ACK (bit 5), the process is acknowledged witha 1−signal each.

2. If the actual position should be output in millimetres or thespeed in millimetres/second (or correspondingly in de�grees, etc.), the effective stroke length must be measuredand input in 1/100 mm or 1/100°. This requires setting thebit UNIT in the control byte CCON to 1 (Z 1/100 mm).

Measuring errors in the input have a negative effect on themaximum achievable accuracy. This applies especially for the swivel modules, for which thescale used by its nature does not permit measurement in1/100°. That is, an entry of 27000 (32−bit integer) or 270.00(decimal) equals the nominal swivel angle of 270°. But theexact angle between the stops can differ from it.

3. Commissioning


The effective stroke length is specified either in the 32−bitinteger or decimal format (depending on the bit UNIT) inthe output data byte 0 ... 3. For the length to be accepted,the bits PARAM0 and PARAM1 must equal 0.

The value is accepted with the bit LOAD_P = 1.Confirmation takes place through the bit ACK = 1 in thestatus byte SCON.

3. A zero point can be defined with the bit REF = 1.Confirmation takes place through the bit ACK = 1. REF_OK is already previously = 0. Negative values are output below the zero point, positivevalues above it.

If a zero point is established, it remains stored even afterswitching on or off.

Generally: Play within the measurement application has a negative effect on the achievable accuracy.

Tip: You can also perform all one−time settings with the CPX−FMT. Fig.�3/4 shows the effective stroke length being written as an example.

B.1 CPX−FEC

General information on configuration using the FST isprovided in the CPX−FEC manual (type P.BE−CPX−FEC−...).Detailed information on operating the FST can be found in theFST manual (type P.BE−FST−...).

B.1.1 Configuration

Use Festo Software Tools (FST 4.1 or higher) with theHardware Configurator in order to configure your CPXterminal with CPX−FEC.

To configure the CMIX, this must be in the catalogue of theCPX configurator (CPX terminal / Technology module /CPX−CMIX...). You may require an FST software update for this(CPX configuration update):

è www.festo.com è Downloads è Download Area:Software, Drivers and firmware è Enter search term: CMIX

CautionIf you have connected a CPX terminal to your PC forconfiguration: Test projects and programs at first withoutactive actuators or without compressed air. You will then avoid damage in the test phase.

I/O configuration / CPX configuration

You can create the configuration in the following ways:

� Nominal/actual comparison in the editor mode

� Change to the online mode

� Manual configuration with the Hardware Configurator

The first two methods require the CPX terminal to beconnected and ready for operation. The hardwareconfiguration with the CMIX is automatically recognised.



With manual configuration, the CMIX can initially beconfigured without a connection to the CPX terminal.

B.3 CPX−FB11 (DeviceNet)

General information on configuration is provided in theCPX−FB11 manual (type P.BE−CPX−FB11−...).

B.3.1 Configuring DeviceNet station properties (EDS)

When starting up a new DeviceNet station for the first time,you must inform your configuration program about certainproperties of the station.

The features of the various slaves are usually administered bythe configuration program in a list or library e.�g. EDS library(EDS for electronic data sheets).

The following possibilities can be used with a CMIX:

� Install an EDS file: Modular EDS. Parameterising of technology modules such as the CMIXis only supported via modular EDS.

� Manually enter the slave features (no parameter settingpossible).

Observe the notes in the manual for the CPX−FB11.

Reference source for EDS files

Reference source Current EDS files, icon files and information on the EDS filescan be found under the following address in Internet:




Installing a modular EDS file

You will require the following files for the CPX terminal:

File type File name Language Description

EDS cpx_chassis.eds English Base file for modular EDS.

EDS cpx_fb11...eds English Provides the communication adapter in theconfiguration program.

EDS cpx_...eds English There is an EDS file for every module type. It contains the information needed forconfiguration and parameterisation.

ICO cpx_...ico � Icon file for representing the CPX terminal ormode in the configuration program.

Tab.�B/13: Configuration files (modular EDS) for the CPX terminal for DeviceNet

Installing modularEDS�files

· Install the files with your configuration program.

You must install at least the Chassis EDS and the EDS files ofthe required modules. Recommendation: Install all EDS files.

Icon files Depending on the configuration program used, you canassign icon files (.ico format) to the CPX terminal or the CPXmodules. The CPX terminal or the modules will then berepresented accordingly in the configuration program.

Notes on installing the EDS files and the icon files can befound in the documentation for your configuration program.
