Description:
The following applies for a synchronous reluctance motor:
Displays the transition value for the start of the evaluation of the optimum flux characteristic.
The value is referred to the rated motor torque.
Note
The transition value corresponds with the lower limit of the flux setpoint (p1581).
For a lower absolute torque setpoint, the flux setpoint remains at the lower limit (p1581).

Description:
The following applies for a synchronous reluctance motor:
Sets the scaling of the rate time Tv for dynamic flux increase when the torque is quickly established.
The value is referred to the inverse value of the rated motor frequency.
Tv = p1567 / 100 % / p0310
