little info to start controller is a cs-labs csmio/ip-a with amc 25a20 drives.
the ip-a manual shows a basic wiring diagram wih a pilz pnoz x7 safety relay.
so the ip-a need 24v input.so 24v to pin 13 on the pnoz x7 and should output
24v to pin 14 to the input of the ip-a.
the drives need to ground the inhibit in pin. so can I just ground pin 23 on the
pnoz x7 and it should output ground to pin 24 to the inhibit in pin on the drive ?
and for the fault. the drives output ttl 5v on a fault but the pnoz x7 needs 24v.should
I just use a 5v relay to switch it to 24v. or is there a better way?

Hi Pitchblack650, I have the csmio/ip-s and a pnoz x7. I have done basically the same as you. Pins 13-14 supplying 24v to inputs on controller and pins 23-24 supplying 24v to a timer relay then to a opto board bringing it down to 5 volt for servo drive disable. Also used opto board to reverse from 5v to 24v to bring servo drive alarm back to the controller.
The reason I have the timer is that I wanted the drive to come to a controlled stop instead of a "freewheel" stop. As the disable on the drives cuts the HV input and it has no braking effort. Is set at about 0.30 seconds.

thanks alan xr8, didn't think of using the opto board to reverse from 5v to 24v for the fault .
how did you wire them up for the fault, ?

Hi Pitchblack650,
I have 5 Granite devices VSD-E drives and I can assign the I/O's on them. Have a search around for some info on them and find out if your drives have fault/error out.

fault out from the manual
TTL level (+5 V) output becomes high when power devices are disabled due to at least one of the following conditions: inhibit, output short circuit, over voltage, over temperature, power-up reset.

Doesn't seem like a problem to feed it back to the controller then. I used one of these opto boards
4 Channel Opto-Isolator on DIN-rail Mount :: Signal Isolators :: Signal Conditioners :: Welcome to Ocean Controls.
Good luck
