8.9.2 Mode Switch (P/PI Switching)
The mode switch automatically switches between proportional and PI control. Set the switching condition
with Pn10B.0 and set the level of detection points with Pn10C, Pn10D, Pn10E, and Pn10F.
Overshooting caused by acceleration and deceleration can be suppressed and the settling time can be reduced
by setting the switching condition and detection points.
