I have an issue with Power Flex 525 during running processing, the VFD stopped suddenly while the PLC and VFD connection ok, VFD does not have any fault, The command from PLC oki but the VFD does not run, no feedback on the output Frequency, and the current
Could you please give me advice?
Thank
 
Can you check your drive status b006. There you can check the safety status.
I would also look at the b012 Control Source to make sure that the start and frequency source are right.
I would also check to make sure the stop jumper is in place. Pin 11-1.
