4.7.4 Limiting Servomotor Speed During Torque Control
During torque control, the servomotor is controlled to output the specified torque, which means that the servomotor speed
is not controlled. Accordingly, when an excessive reference torque is set for the mechanical load torque, it will prevail over
the mechanical load torque and the servomotor speed will greatly increase.
This function serves to limit the servomotor speed during torque control to protect the machine.

· Set the servomotor speed limit value during torque control.
· Pn005=H .□□ 1 □， Pn406 is motor speed limit value.
· The servomotor’s maximum speed will be used when the setting in this parameter exceeds the maximum speed of the
servomotor used.
