The OP says that the system was ordered to run on 144V so I'd imagine it is still set that way. The DMOC445-II tended to be paired with an AC-24 motor. That motor uses an incremental encoder for position feedback. My guess is that the encoder signal is not getting through probably. On those old DMOC445s there were sometimes troubles with noise on the encoder cable. They made a special box that you put in line on the encoder cable to clean up the signal before it gets to the DMOC. If you don't have that then it is possible that the signal is getting too noisy. At any rate, if the OP has an oscilloscope it might be handy to try to scope the encoder signal lines. That won't be too terribly straight forward to do though.
