4.10 Operation Check

Table 4.10-2
Speed control 1
(Speed command filter)
If an excessive overshoot or undershoot occurs for a speed
command change, increase the filter constant.
If motor response is slow for a speed command change, decrease
the filter constant.
Speed control 1
(Speed detection filter)
If ripples are superimposed on the speed detection signal so that the
speed control gain cannot be increased, increase the filter constant
to obtain a larger gain. It is not necessary to change the factory
default normally.
If hunting is caused in the motor speed control, decrease the gain. If
speed mismatch or excessive speed deviation (ere ) occurs
because the motor response is slow, increase gain.
Speed control 1
I (Integral time)
If speed mismatch or excessive speed deviation (ere ) occurs
because the motor response is slower, decrease the integration
time.
If the load inertia is large, increase the integration time.
