AUTOMATIC SPEED REGULATOR (ASR)

A . C 5 - 0 1 : ASR Proportional Gain 1
(ASRP1)
C 5 - 0 2 : ASR Integral Time 1
(ASRI1)
Parameters C 5 - 0 1 and C 5 - 0 2 provide adjustments to enable the optimum
performance during load disturbances. The proportional gain ( C 5 - 0 1 ) adjusts the
amount of instantaneous droop as a function of loss, and provides damping from load
disturbances such as speed reference change, or a change in load. The integral time (
C 5 - 0 2 ) adjusts the response time of the drive to the load disturbances.
NOTE: Speed control response is increased by increasing the proportional gain
setting and decreasing the integral time. However, instability or hunting may occur
between the drive and the load if C 5 - 0 1 (ASR Proportional Gain) is set too
high, or C 5 - 0 2 (ASR Integral Time) is set too low.
