Pn407
Speed Limit During
Torque Control rpm
0 ~ 10000 Sets a motor speed limit in torque control.
Used to prevent machine overspeed in torque
control.
The limit is the maximum speed of the servo
motor if a value higher than the maximum
speed of the applied motor is set into Pn407.
Note: Principle of Speed Limit
Values outside the limit speed range return to
be within the limit speed range by returning a
negative torque proportionate to the speed
differential with the limit speed.Therefore, the
actual motor speed limit generates a band
according to the load conditions.
