Hello,
I'm using a Kinetix 350 Servo Drive, and the documentation is showing an M1 Contactor to switch incoming power to the drive. The problem is, none of the documentation tells us what is actually energizing the coil of this contactor.
In applications where I've used Kinetix 6000 drives, the coil of this contactor is wired to the Contactor Enable (CED), and as long as the drive, itself, has no fault conditions, the coil will be energized through the Contactor Enable relay.
The Kinetix 350 has no such Contactor Enable.
What is the purpose of this M1 Contactor, considering that there is already a Safe Torque Off (STO) on this drive? I see no need to kill incoming power to the drive in the case of an e-stop or door opening since there is an STO.
Should I energize this contactor through my safety system (e-stop monitoring, etc.) or should I simply monitor the drive status and energize this coil from an output from the PLC?
Thanks!
