Allen bradley Variable frequency drives

We have Allen Bradley VFD CAT1336F-B050-AN-EN. We are facing problem that when we give RUN command from HMI, then drive card 1336F-MCB-SP1K shows that drive is running by turning ON RUN (GREEN) LED, but on HMI drive remains on stopped condition and not goes on “at speed” position and also drive not run physically.

We have this same issue on other Allen Bradley Drives: 1336F-BP400-AN-EN-NCM & 1336F-B200-AN-EN. Please give valuable suggestions to solve the problem. email address: [email protected]
