0.01% 15000
Set the speed limit for torque reference commands 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 will be
overpowered by the torque reference and the motor speed greatly increases.
The torque reference speed limit functions to limit the Servomotor speed during torque control to protect the machine.
No speed limit Speed limit used
Either the Torque Reference Speed Limit setting (OW
0E) or the SERVOPACK's torque control speed limit (Pn407),
whichever is lower, will be used as the speed limit.
