Speed Waveform Monitoring Method
To make small adjustments of ASR parameters, monitor the speed waveforms when you make the adjustments.
Table 12.21 shows example settings of parameters to monitor speed waveforms.

Based on this setting, MFAO terminal AM outputs the output frequency after SFS in a 0 V to 10 V (0% to 100%)
range. The MFAO common is terminal A0V:
The manufacturer recommends that you monitor the output frequency after SFS and the motor speed for delays in
response and differences in reference values.

Adjust ASR Parameters
Use Table 12.22 to adjust ASR. The table lists parameters for motor 1. You can make the same changes to motor 2
parameters when you run a second motor.
Note:
When adjusting the proportional gain and integral time, adjust the proportional gain first.
Speed response is slow.
Overshoot or undershoot occurs 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.
Oscillation at high speed and response is too slow at low
speed.

• Increase C5-01/C5-03 [ASR PGain 1/ASR PGain 2].
• Decrease C5-02/C5-04 [ASR ITime 1/ASR ITime 2].
• Decrease C5-01/C5-03.
• Increase C5-02/C5-04.
• Decrease C5-01/C5-03.
• Increase C5-02/C5-04.
• Increase C5-06 [ASR Delay Time].
When A1-02 = 6 [Control Method = PM AOLVector], use
C5-01 to C5-04 to set the best ASR settings for high and
- low speed. Use C5-07 [ASR Gain Switch Frequency] to
switch the ASR proportional gain and ASR integral time
as specified by the output frequency.
