1st switch-off path:
Maintain wiring of output stage enable [X1.21] and run parallel to STO-A [X40.1].
In order to connect the reference potential, connect GNDA [X40.2] with 0 V [X40.8].
2nd switch-off path:
Now run the driver supply wiring [X3.RELAY] to STO-B [X40.3].
In order to connect the reference potential, connect GNDB [X40.4] with 0 V [X40.8].
Acknowledgment contact:
Reverse the connection for the acknowledgment contact [X3.5] and [X3.6] to [X40.5] and [X40.6].
Note
During operation, the acknowledgment contacts on the CMMP-AS and the
CMMP-AS-...-M0 exhibit compatible behaviour.
When the logic supply (24 V) is switched off, they behave differently:
–
CMMP-AS: Contact closed.
–
CMMP-AS-…-M0: Contact open.
Information for configuration
The CMMP-AS-...-M0 exhibits a higher peak power than the CMMP-AS. Higher positioning speeds can
therefore be reached depending on the application. Use of this feature represents an essential modific
ation to the machine.
Note
The parameter record of the CMMPAS must be transferred with the same values to the
parameter record of the CMMPAS...-M0. If these values are increased, which in turn
poses a new or enhanced risk, a new risk assessment must be performed on the
machine.
Note
Once the motor controller has been replaced, the safety function must be validated in
accordance with the machine manufacturer's specifications.
