2. Details of control
The operation with the torque limit is as follows.
*5. While the servo motor is stopped by the torque limit function, the "Servo status: during torque limit"
flag remains ON.
3. Precautions for control
• If the zero return torque limit value exceeds the torque limit setting, an error occurs.
• If the torque limit function causes the operation to stop, drop pulses remain in the deviation counter. After
the load torque is removed, the operation continues according to the remaining pulses.

If the positioning parameter setting is changed, issue a positioning control parameter command
to validate the new setting.

When the torque output setting is changed during operation, the changed value is reflected in
operation and stored in the torque limit setting.

When the torque output setting is changed during stop, the changed value is not reflected in
operation and is stored in the torque limit setting when the START command turns ON from
OFF.
