4.12.3 Circuitry with use of the STO safety function [X40]
To work safely with the safety function STO – “Safe Torque Off”, please observe the in
formation in the documentation è GDCP-CMMP-AS-M0-S1-... .
4.12.4 Circuitry without use of the STO safety function [X40]
If you do not need the integrated safety function STO in your application, to operate the
motor controller you must connect the X40 interface, as depicted in Fig. 4.8.
This deactivates the integrated safety function!
When using this circuitry for the CMMP-AS-...-M0, safety in the application must be en
sured through other appropriate measures.
