Why does the motor run correctly in bypass and incorrectly in AFC?

FA170932

28 September 2021

Issue:
The motor runs forward in bypass but reverse in AFC.

Product Line:
ATV21, ATV212, SFlex

Environment:
All S-Flex type SFD212 enclosed drives

Cause:
None

Resolution:
If Bypass rotation is correct swap any 2 output leads on the power converter (the terminals labeled U,V, and W). Swapping any two terminals at the overload will result in the motor rotating incorrectly in bypass and correctly in AFC.
