C5: Automatic Speed Regulator (ASR)
The ASR controls the motor speed in V/f w/PG, CLV, AOLV/PM, and CLV/PM control modes and adjusts the output frequency
(V/f w/PG) or torque reference (CLV, AOLV/PM, CLV/PM) to minimize the difference between frequency reference and
actual motor speed.

Adjusting the ASR Parameters
Perform Auto-Tuning and set up all motor data correctly prior to adjusting ASR parameters.
Use analog output signals to monitor the frequency reference after softstarter (U1-16) and the motor speed (U1-05) when
adjusting the ASR. Refer to H4: Multi-Function Analog Outputs
on page 272 for details on setting up analog output
functions.
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.
Adjusting the ASR Parameters in V/f Control with PG
In V/f Control with PG, the ASR settings change between two sets of parameters depending on the motor speed as described
in C5-01, C5-03/C5-02, C5-04: ASR Proportional Gain 1, 2/ASR Integral Time 1, 2 on page 199.
