Cumulative Travel Exceeded (Torque Control)

What does SV0423 mean?

This servo alarm is issued if the cumulative travel value (error counter value) during torque control exceeds the maximum allowable value set in parameter 1885. This alarm is enabled when bit 4 (TQF) of parameter No. 1803 is set to 0, indicating that follow-up is not performed during torque control. Exceeding this limit suggests excessive movement or an issue with the torque control mechanism.

• The cumulative travel distance for the axis has surpassed the limit defined in parameter P4-12, indicating excessive wear or usage.
• The torque control limits (P3-10, P3-11) have been reached for an extended period, suggesting a mechanical bind or overload.
• The axis is repeatedly commanded to move beyond its practical physical limitations in torque control mode.
• An internal servo parameter (e.g., P3-15) related to cumulative travel monitoring has been incorrectly set or triggered prematurely.

Click steps to track your progress.

1. 1

   Verify the value of parameter No. 1885 (Maximum allowable value for total travel during torque control) for the affected axis.

2. 2

   Check bit 4 (TQF) of parameter No. 1803 to confirm it is set to 0, enabling this alarm for the axis.
