Automatic Speed Regulator (Asr) Tuning - Magnetek Impulse G+ series 4 Instruction Manual

Increase the torque compensation time constant in 10 ms increments when the motor's output
current is unstable. Decrease this value when speed response is slow.

Automatic Speed Regulator (ASR) Tuning

The ASR controls the motor speed in the FLV control method and adjusts the output torque
reference to minimize the difference between frequency reference and actual motor speed.
The figure below illustrates ASR functionality:
Perform Auto-Tuning and set up all motor data correctly prior to adjusting ASR parameters.
Generally when tuning the ASR, optimize the ASR gain before adjusting the integral time settings.
Always make adjustments with the load connected to the motor.
Function
Sets the gain for the automatic
torque (voltage) boost function and
helps to produce better starting
torque.
Sets the torque compensation filter
time.
Sets torque compensation at
forward start as a percentage of
motor torque.
Sets torque compensation at
reverse start as a percentage of
motor torque.
Sets the time constant for torque
compensation at forward start and
reverse start (C04-03 and C04-
04).
Sets the torque compensation time
2.
