• Use analog output signals to monitor U1-16 [SFS Output Frequency] and U1-05 [Motor Speed] when you adjust
the ASR.

ASR Adjustment Procedure for EZOLV
Do this procedure to adjust ASR parameters:
1. Run the motor at zero speed or low speed and increase C5-01 [ASR Proportional Gain 1] until immediately
before vibration starts to occur.
2. Run the motor at zero speed or low speed and decrease C5-02 [ASR Integral Time 1] until immediately before
vibration starts to occur.
3. Check for oscillation when you run the motor at maximum speed.
4. If oscillation occurs, increase C5-02 and decrease C5-01.
When there is no oscillation, the adjustment procedure is complete.
5. Set the low-speed gain. Run the motor at zero speed or low speed and increase C5-03 [ASR Proportional Gain 2]
until immediately before vibration starts to occur.

6. Set the low-speed integral time. Run the motor at zero speed or low speed and decrease C5-04 [ASR Integral Time
2] until immediately before vibration starts to occur.
7. Set C5-07 [ASR Gain Switchover Frequency].
8. Check for oscillation when you run the motor at speeds higher than C5-07.
Note:
• If overshooting occurs when acceleration ends, decrease C5-01 and increase C5-02.
• If there is undershoot at stop, decrease C5-03 and increase C5-04.

Use MFDI Switch for Proportional Gain
You can use the input terminals set for H1-xx = 77 [ASR Gain (C5-03) Select] to switch the proportional gains set
with C5-01 and C5-03. When the configured input terminal is deactivated, the proportional gain set for C5-01 is
selected. When the terminal is activated, the proportional gain set for C5-03 is selected. The proportional gain
changes linearly over the time set in C5-02 [ASR Integral Time 1]. The signals from this MFDI are more important
than C5-07 [ASR Gain Switchover Frequency].
