 C5-01 ASR Proportional Gain 1
Setting Range: 1.00 to 300.0
Factory Default: 20.00
The ASR proportional gain 1 adjusts the speed in response to speed deviation, and softens the effect of changes in load. Speed
response increases as the proportional gain is increased. However, the load may become unstable if the ASR proportional gain
is set too high.
Note: When parameter A1-02=1 (V/f control with PG) the factory default setting is 0.20. When parameter A1-02=3 (Flux Vec-
tor) the factory default setting is 20.00.
 C5-02 ASR Integral Time 1
Setting Range: 0.000 to 10.000 sec
Factory Default: 0.500 sec
The ASR integral time 1 adjusts the Drive’s response time to changes in load. Speed response increases as the integral time is
decreased. However, the load may become unstable if the ASR integral time is set too low.
Note: When parameter A1-02=1 (V/f control with PG) the factory default setting is 0.200. When parameter A1-02=3 (Flux
Vector) the factory default setting is 0.500.
 C5-03 ASR Proportional Gain 2
Setting Range: 1.00 to 300.0
Factory Default: 20.00
The ASR proportional gain 2 is an additional proportional gain adjustment that can be enabled by either a multi-function
contact input (H1-0x = 77) or the ASR switching frequency (C5-07).
Note: When parameter A1-02=1 (V/f control with PG) the factory default setting is 0.02. When parameter A1-02=3 (Flux Vec-
tor) the factory default setting is 20.00.

 C5-04 ASR Integral Time 2
Setting Range: 0.000 to 10.000 sec
Factory Default: 0.500 sec
The ASR integral time 2 is an additional integral time adjustment that can be enabled by the ASR switching frequency (C5-
07).
Note: When parameter A1-02=1 (V/f control with PG) the factory default setting is 0.050. When parameter A1-02=3 (Flux
Vector) the factory default setting is 0.500.
