2.3 C: Tuning
Solving Problems During ASR Setup
Use Table 2.14 when making adjustments to ASR. Though the parameters listed below are for motor 1, the same changes
can be made to the corresponding motor 2 parameters when running a second motor.
Slow response to speed changes or
speed deviation lasts for too long
Overshoot or undershoot at the end
of acceleration or deceleration
Vibration and oscillation occur at
constant speed
Oscillation at low speed and
response is too slow at high speed (or
vice versa)
■ C5-01, C5-03 / C5-02, C5-04: ASR Proportional Gain 1, 2 / ASR Integral Time 1, 2
These parameters can be used to adjust the responsiveness of the ASR.
Note: C5-01 is automatically set when ASR Tuning is performed (T1-01 = 9 or T2-01 = 9).

These parameter settings will function differently depending on the control mode.
CLV
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. Also refer to

• Increase the ASR gain.
• Decrease the integral time.
• Decrease the ASR gain.
• Increase the integral time.
• Decrease the ASR gain.
• Increase the integral time.
• Increase the ASR delay time (C5-06).
• V/f control: Use C5-01/02 and C5-03/04 to set up different ASR
settings at minimum and maximum speed.
• CLV: Use C5-01, C5-02 and C5-03, C5-04 to define optimal ASR
settings for high and low speed. Use C5-07 to define a switching
frequency.
