EXCESS ERROR (MOVING)

What does SV0411 mean?

This servo alarm is generated when the positioning deviation for an axis exceeds the limit set in parameter 1828 while the axis is in motion. This causes an immediate stop of operation, similar to an emergency stop. An incorrect setting of parameter 1828 can lead to machine or workpiece damage, as it defines the maximum permissible tracking error during movement.

1. 1

   Verify the value set in parameter 1828 (Positioning deviation limit for each axis in movement) for the affected axis.

2. 2

   Ensure parameter 1828 is set to the rapid traverse rate plus a suitable margin. Refer to parameter No. 1420 for the maximal feedrate and parameter No. 1825 for actual servo loop gains when calculating the correct value for the axis.
