Description
Rotor time constant tuning.
This parameter can be used to improve torque accuracy in
closed-loop control of an induction motor. Normally, the motor
identification run provides sufficient torque accuracy, but
manual fine-tuning can be applied in exceptionally
demanding applications to achieve optimal performance.
Note: This is an expert level parameter and should not be
adjusted without appropriate skill.
Rotor time constant tuning.
Defines the relative output voltage boost at zero speed (IR
compensation). The function is useful in applications with a
high break-away torque where vector control cannot be
applied.

Enables the motor model temperature adaptation. Estimated
motor temperature can be used to adapt temperature
dependent parameters (e.g. resistances) of motor model.
