• Increase the settings for C5-01 (Speed Control Proportional Gain 1) and reduce
C5-02 (Speed Control Integral Time 1).
• Enable Feed Forward Control and perform Inertia Auto-Tuning in CLV.
• Set H6-02 to the value of the speed feedback signal frequency when the motor
runs at the maximum speed.
• Adjust the input signal using parameters H6-03 through H6-05.
Check and correct parameter F1-01.
Check the setting for the overspeed detection level and the overspeed detection
time (F1-08 and F1-09).
