C5-01, C5-03/C5-02, C5-04: ASR Proportional Gain 1, 2/ASR Integral Time 1, 2
These parameters adjust the responsiveness of the ASR.
Note: C5-01 is automatically set when ASR Tuning is performed (T1-01 = 9 or T2-01 = 9).

Parameters C5-01 and C5-02 determine the ASR characteristics at maximum speed. Parameters C5-03 and C5-04 determine
the characteristics at minimum speed.

Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
In these control modes, parameters C5-03 and C5-04 define the ASR gain an integral time at zero speed. The settings in C5-01
and C5-02 are used at speeds above the setting in C5-07. C5-07 is set to 0 as the default so that C5-01 and C5-02 are used
over the entire speed range. Refer to C5-07: ASR Gain Switching Frequency on page 164.

The gain set in C5-03 can also be activated with a digital input programmed to “ASR gain switch” (H1-oo = 77). When the
terminal is open, the drive uses the ASR gain level set by the pattern in the figure above. When the terminal closes, C5-03 is
used. The integral time set to C5-02 is used to change linearly between these settings. The ASR gain switch command from
a multi-function input terminal overrides the switching frequency set to C5-07.
