How do I configure an ATV71 drive for a synchronous motor?

FA234580

23 July 2022

Issue:
Synchronous motor set up on an ATV71

Product Line:
ATV71

Environment:
All models and serial numbers

Cause:
None

Resolution:
The CTT  [Motor control type] of the ATV71 drive must be changed from the default value of UUC [SVC V] to SYn [Sync. mot].  This selection makes the asynchronous motor parameters inaccessible, and the synchronous motor parameters accessible.

The following parameters can be acquired from the motor nameplate and must be entered into the motor control menu:
nCrSNominal sync current
nSPSNominal sync mot speed
PPnSPole pairs number (sync)
PHSSync. EMF constant
PrTPower Ident.
