160.1
Magnetization time
Ramp on field current during magnetization. Actual magnetization time depends on how
the actual flux rises in the motor.
161.1
Minimum speed threshold OL
Speed reference below which speed estimation is suspended.
161.2
Minimum speed delay OL
Time which must elapse before speed estimation is suspended when speed is below the
threshold Z161.1–.
163.1
Flux estimator gain
Gain of motor model flux estimator. Higher values favor smooth low speed operation. Low
values give better performance at higher speeds.
167.1
Catch enable
The Catch on Fly is active for the next pulse enable, if this parameter is set to 1.
167.2
Catch flux estimator gain
Proportional gain of the motor model flux estimator while catch operation is active.
167.3
Catch demagnetization time
For motors with a high rotor time constant, this parameter can be used to force a delay
between pulse disable and subsequent pulse enable. While the catch operation is active,
there might occur a short term regenerative operation of the motor due not known rotor
position. If the delay between pulse disable and pulse enable is short compared to the
rotor time constant and the rotor speed is high, the maximum DC link voltage might be
