If the stability is not adequate close to the changeover speed, it may make sense to increase the parameter value.
On the other hand, very low changeover speeds can negatively impact the stability.
Note: The changeover speed applies for the changeover between open-loop and closed-loop control mode.
Description: Sets the hysteresis for the changeover speed of the motor model for encoderless operation.
Dependency: Refer to: p1755
Note: The parameter value refers to p1755.
Extremely small hystereses can have a negative impact on the stability in the changeover speed range, and very
high hystereses in the standstill range.
Description: Sets the proportional gain of the controller for speed adaptation without encoder.
Description: Sets the integral time of the controller for speed adaptation without encoder
Description: Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM): Rs, Lh, and offset compensation.
Permanent magnet synchronous motor (PEM): kT
