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

Issue:
Synchronous motor set up 
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:
nCrS Nominal sync current
nSPS Nominal sync mot speed
PPnS Pole pairs number (sync)
PHS Sync. EMF constant
PrT Power Ident.
