Has this been running for a while and suddenly will not start? Or, is it newly commissioned and will not start? active_engg I have also face same problem . Switching on inhibited r2-44 showing.

And drive does not show any fault. Only r2-44 occurred When power off and again on then it running after some time of running r2 again goes to 44 and no run command taken

I have tried so many things but problem still not solved. 0_Einstein It sounds like the safety integrated function required an E-Stop activation and clear with a period of "after some time" (the default is 80 hours I think). active_engg Parameter r2 shows 44 And this is 2 year old running drive.
