Código 231-E220: Standstill monitoring SKERN-CC %1

[Cause of error] - SKERN-CC detected an impermissibly large axis movement in the SOS safety condition. The standstill speed, however, was not exceeded. The maximum permissible path is defined in the machine parameter MP positionRangeVmin. Possible causes: - Machine parameter "positionRangeVmin" is defined too small. - The brake was deactivated before the position controller was closed. - The brake was not activated before the position controller was opened. - When an axis was switched on, some existing following error was corrected. - The brake is defective. - There was an attempt to move an axis in the SOS condition (PLC?) [Error correction] - Check the entry in machine parameter positionRangeVmin. - Check the sequence of deactivating the brake and closing the position controller. - Check the sequence of activating the brake and opening the position controller. - Check whether there is a following error after an axis is locked. - Inform your service agency.
