the speed loop is switched to P control.
Used to shorten the settling time. In general, the speed loop gain must be raised in order to shorten
the settling time, but in this case overshooting and undershooting are suppressed.
the user constant (Pn10E), the speed loop is switched to P control.
When P control switching is not used, and PI control is always used, the torque during acceleration
and deceleration may be saturated and the Servomotor speed may overshoot or undershoot. Using
P control switching suppresses torque saturation and eliminates Servomotor speed overshooting
and undershooting.
Speed loop gain raised.
