Fig. 116: When Pr.11-33 is set to 0 or 1, you can set the torque command in Pr.11-34.
When Pr.11-33 is set to 2, 3 or 5, Pr.11-34 only displays the torque command.

This parameter sets the torque command. When Pr.11-27 is 250% and Pr.11-34 is 100%, the actual torque
command = 250 × 100% = 250% of the motor rated torque.
The drive saves the settings before power is OFF.

When the setting is too long, the control is stable but the control response is delayed. When the setting is too short,
the response is quick but the control may be unstable. Adjust the setting according to your control and response
situation.

Speed limit function: when you use the torque control mode, if the torque command is greater than the load, the
motor accelerates until the motor speed equals the speed limit. At this time, it switches to speed control mode to
stop acceleration.
Pr.11-36 = 1:
When the torque command is positive, the forward speed limit is Pr.00-20 and the reverse speed limit is Pr.11-38.
When the torque command is negative, the forward speed limit is Pr.11-37 and the reverse speed limit is Pr.00-20.
Example:
In an unwinding application, if the torque command direction is different from the motor operating direction, the load
drives the motor. In this case, the speed limit must be Pr.11-37 or Pr.11-38. Only in normal applications, that is
