Pn10B.0=0: Torque Reference Used as Detection Point
With this setting, if the value of torque reference input exceeds
the torque set in parameter Pn10C, the speed loop switches to P
control.
The SERVOPACK is factory-set to this standard mode (Pn10C =
200).

Operating Example
If the system is always in PI control without using the mode
switch function, the speed of the motor may overshoot or under-
shoot due to torque saturation at the time of the acceleration or
deceleration of the motor. The mode switch function suppresses
torque saturation and eliminates the overshooting or undershoot-
ing of the speed of the motor.
