 Field Forcing
The field forcing function controls the motor flux and compensates the flux establishment delay of the motor.
Thereby it improves the motor responsiveness on changes in the speed reference or the load.
Field forcing is applied during all operation conditions except DC Injection.
Using parameter d6-04 a field forcing limit can be applied. A setting of 100% is equal to the no-load current
set in parameter E2-03.

 Setting Motor 1 Parameters
In vector control method, the motor parameters are set automatically during autotuning. If autotuning does not
complete normally, set them manually.
