6.9.5 Using the Mode Switch (P/PI Switching)
6-70
<Example>
If the mode switch function is not being used and the SERVOPACK is always operated with PI control, the
speed of the motor may overshoot or undershoot due to torque saturation during acceleration or deceleration.
The mode switch function suppresses torque saturation and eliminates the overshooting or undershooting of
the motor speed.
Using the Speed Reference Level to Switch Modes
With this setting, the speed loop is switched to P control when the value of speed reference input exceeds the
speed set in Pn10D.
<Example>
In this example, the mode switch is used to reduce the settling time. It is necessary to increase the speed loop
gain to reduce the settling time. Using the mode switch suppresses overshooting and undershooting when
speed loop gain is increased.
