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).

Magnetization rate time scaling / Mag Tv scale
Access level: 4
Can be changed: T, U
Unit group: -
Min:
0 [%]
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
Dependency:
See also: p1401
Note
The "Dynamic load-dependent flux boost" function can be deactivated using p1401.9 = 0.
