−32768 to 32767 0.01% 15000
Set the speed limit for torque references as a percentage of the rated speed.
Torque control is used to control the Servomotor to output the specified torque, so it does not control the motor speed. Therefore,
when an excessive reference torque is set relative to the load torque of the machine, the machine’s torque is overpowered by the
torque reference and the motor speed rapidly increases. The Speed Limit at Torque Reference functions to limit the Servomotor
speed during torque control to protect the machine.
No speed limit Speed limit used
Either the Speed Limit at Torque Reference (OW††0E) or SERVOPACK’s Torque Control Speed Limit (Pn407) is effective,
whichever is lower.
