phase motor controllers CMMP-AS-...-3A-M0
For the initial start-up of the motor controller without safety equipment, the motor
controller CMMP-AS-...-M0 with a minimum circuitry corresponding to Fig. 3 can be
wired with an emergency stop switch ( 2 ).
Note
Never bypass safety functions.
Carry out the minimum circuits of the inputs STO-A/STO-B and 0V-A/0V-B for the
initial start-up so that they will be forcibly removed when the final protection cir­
cuitry is executed.
7 Commissioning
Note
Commissioning does not mean the first intended use by the final customer.
Rather, it means commissioning by the machine manufacturer when the machine
is set up.
Note
Loss of the safety function!
Lack of the safety function can result in serious, irreversible injuries, e.g. due to
uncontrolled movements of the connected actuators.
• Operate safety function only when all safety measures have been introduced.
• The safety function must be checked and, prior to the intended use, a corre­
sponding validation must be carried out.
Incorrect wiring or use of incorrect external components which were not selected
corresponding to the safety category can lead to loss of the safety function.
• Carry out a risk assessment for your application and select the circuitry and
components accordingly.

7.1 Prior to commissioning

Carry out the following steps in preparation for the initial start-up:
1. Make sure the motor controller is correctly mounted.
2. Check the electrical installation (connecting cable, pin allocation è section 6).
Are all PE protective earth conductors connected?

7.2 Performance test

Note
The STO function must be validated after the installation and after any modifica­
tion to the installation.
This validation must be documented by the person performing commissioning.
To help you with commissioning, you can find sample checklists in the docu­
mentation GDCP-CMMP-AS-M0-S1-... on the CD accompanying the motor con­
troller.

8.1 Obligations of the operator

3
The operational capability of the safety device is to be checked at adequate inter­
vals. It is the responsibility of the operator to choose the type of check and time
intervals in the specified time period. The check is to be conducted so the flawless
functioning of the safety device in interaction with all the components can be veri­
4
fied.

8.2 Maintenance and care

The safety function in the motor controller CMMP-AS-...-M0 requires no mainten­
4
ance.

9.2 Error messages

The motor controller displays malfunctions cyclically in the seven-segment display
on the front side of the motor controller. Error messages with "E" (for error), a
main index (xx) and a sub-index (y) display, e.g. E 5 1 0. Warnings have the same
number, but are represented with previous and subsequent middle benches, e.g. -
1 7 0 -. Fig. 5 lists the error messages that are relevant for functional safety.
è The complete list of error messages can be found in the hardware documenta­
tion GDCP-CMMP-M0-HW-... of the motor controller.
Where error messages cannot be acknowledged, you must first eliminate the
cause. Then reset the motor controller, and check whether the cause of the error,
and the error message, have been eliminated.

10 Repair or replacement of the integrated safety circuit
A repair or replacement of the integrated safety circuit is not permissible. If re­
quired, exchange the complete motor controller.
11 De-commissioning and waste management
Observe the local regulations for environmentally appropriate disposal of electron­
ic modules.
Description
"H": The motor controller is in the "safe status".
This does not mean the same as the information about the status of the
safety function STO (Safe Torque Off ).
For the "unsafe status", no special display is intended; the standard status
displays of the motor controller are depicted.
Actions
–
• Safety circuit defective. No actions
possible; please contact Festo. If
possible, replace with another motor
controller.
–
–
• Control ports STO-A and STO-B are
not actuated simultaneously.
• Control ports STO-A and STO-B are
not wired in the same way.
• Check discrepancy time.
• The safe status was requested with
approved power output stage. Check
inclusion in the safety-oriented inter­
face.
