Allen Bradley Power Flex Alarms

[2106tech]

Looking for some good details on Allen Bradley Power Flex alarms, actually faults or alarms, I'm not sure of the difference exactly, but I'm getting a Ground Fault 13, am I looking at the drive being ground faulted? or the motor?

Thanks!

I'm getting a Ground Fault 13

A ground fault in this case is likely in the motor, I think the fault list tells you to check not only the motor for grounds, but the external wiring also. There is no mention of a ground within the drive.

Here's an expanded list tof the Allen Bradley Power Flex Faults in random order:

• 2 Auxiliary Input
• 39 Phase V to Ground
• 88 Software Fault

This is nuts, I am back where I started at Ground Fault 13. Getting frustrated with the Powerflex alarms
