MAX. ALLOWABLE TOTAL TRAVEL EXCEEDED

What does SV0423 mean?

This servo alarm is issued when the cumulative travel value (error counter value) for an axis operating under torque control exceeds the maximum allowable value set in parameter 1885. This typically occurs when an axis travels beyond its defined limit during torque control without a follow-up action. This alarm is active when bit 4 (TQF) of parameter No. 1803 is set to 0, indicating that follow-up is not performed during torque control.

1. 1

   Check parameter 1885 (Maximum allowable value for total travel during torque control) — verify the set value is appropriate for the application's expected travel under torque control.

2. 2

   Check bit 4 (TQF) of parameter No. 1803 — ensure it is set to 0 if this alarm condition is desired (i.e., follow-up is not performed during torque control).

3. 3

   Evaluate the machine's torque control sequence — reduce the cumulative travel of the axis or adjust the value in parameter 1885 if the application legitimately requires longer travel under torque control within safe limits.
