How to Clear Fault F81 in PowerFlex 40P & 40 Drive

The PowerFlex 40 and 40P drives F81 fault not reset most of time. So, we change the new drive.

First check below points:

1. Check the Ribbon cable (Drive to 20-Comm adapter) are connected properly
2. Check the (RJ45 in drive) RS485 communication cable are connected properly
3. Check the (RJ45 in drive) HIM Display communication cable are connected properly 
4. Check the 22-Comm adapter indication 

 Till Fault (F081) not reset. Continuously fault reset by using the reset button or wait 10 to 20 minutes after that reset automatically. Some time fault not clear means new drive or SMPS board (Drive Inside) to be replace.
