Comm Module Fault 7501
We have a communication fault on our ACs800 drive 7501,and it's not resetting, we have tried replacing the RPBA-01 interface card, and the RMIO board but still we have the same fault.
your assistance will be highly appreciated
Comm Module Fault should be 7510.
Seems your drive is controlled from external master (e.g. PLC) and it lost connection to it.
Because you didn't provide the detailed information, I can make a few comments only:
- is it working well before?
- look for the connection to the master: cable, master is active, there is no change in master settings or settings in ACS800 = par. 51 or 52
- this fault is a program function - can be configured from par. 30.18 but before to change there, better check why you don't have connection to the master.
Otherwise you can't control the drive trough comm channel
Changing of RMIO most probably will not help, and even opposite - you will loose the original settings of the drive (parameters).
My recommendation is to replace the boards only if you are familiar with ACS800.
