[Cause of error] - The maximum permissible path was exceeded in the Safely Limited Increment (SLI) mode. - Possible causes: - The selected increment exceeds the value from the safe machine parameter distLimitJog - The drive overshoots mechanically when the limit position is reached - Drive is not optimally adjusted. [Error correction] - Enter a smaller jog increment. - Check the entry in the safe machine parameter distLimitJog. - When the jog increment end position is reached, use the control's internal oscilloscope to check the actual position value for overshooting. - Adjust the drive. - Inform your service agency.
