Description
This parameter can be used to improve the control
dynamics of a synchronous reluctance motor or a
salient permanent magnet synchronous motor.
As a rule of thumb, define a level to which the output
torque must rise with minimum delay. This will
increase the motor current and improve the torque
response at low speeds.
Optimizer torque limit.
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.
