Issue:
Phase rotation parameter on the ATV312
Product Line:
ATV312
Environment:
All serial numbers, all model numbers.
Cause:
Run forward command results in motor running in reverse rotation.
Resolution:
No, the ATV312 does not have a phase rotation parameter. Typically, correction of rotation is accomplished by swapping 2 motor leads at the VFD output, T1/T2/T3.
In the CtL menu, there is a Rotating Direction parameter (rot) that applies to the the remote keypad FWD/REV button only when the command channel is LCC and speed reference channel is AIU1 or LCC.
Information about the rot parameter can be found in the ATV312 Programming Manual:
