Applied Functions
*4.The variation means the change amount in a millisecond (ms).
E.g. The set value is 200 when the condition is a 10% change in torque in 1 millisecond.
*5.The unit (pulse) of hysteresis is the resolution of the encoder in position control. It is the resolution of
the external encoder in full closing control.
*6. When the set value is 10, meanings of the Gain switching delay time in position control, the Gain
switching level in position control, and the Gain switching hysteresis in position control differ from the
normal case. (Refer to Figure F).
