Actual decreasing time T2=Po213 X target torque/rated torque
6.3.3 Speed limiting at torque mode
This function serves to limit the servo motor speed during torque control to protect the machine.
In torque mode, speed limit includes:
1. Internal speed limit 2. Analog speed limit 3. Speed limited by max rotation speed and actual motor max speed.
The third limit method is constantly enabled, and the rest of methods are limited by some conditions.

Remarks
Po210=0
Use the value set in Po211 as the speed limit.
Po210=1
Inputs an analog voltage command as the servo motor speed limit value, this is valid for
forward/reverse rotation.
Po210=2
Use the lower value between max rotation speed Po002 and actual motor max rotation
speed as the speed limit.
