IMPULSE®•G+ & VG+ Series 4 Instruction Manual – February 2017
5-57
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:
Figure 5-18: Speed Control Block Diagram for FLV
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.
