Código 231-A920: Standstill monitoring SKERN-CC %1

[Cause of error] - SKERN-CC detected an impermissibly large axis movement in the SOS safety condition. The standstill speed (50 mm/min for feed axes or 10 rpm for spindles) was also exceeded. The maximum permissible path in the SOS condition is defined in the machine parameter "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?) - The axis feed-rate enabling by the ApiToSafety datum PP_AxFeedEnable is missing. [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. - Check the interface signal of the SPLC PP_AxFeedEnable for the axis - Inform your service agency 10/2023 [475]
