Code V05-0006: SOS travel distance error
Issue Description & Safety Warning
The Mitsubishi M800/M80 CNC has triggered a critical SOS travel distance error alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Details The command/FB travel distance, which had exceeded th e SOS travel distance tolerance (+/-) (set by param- eter) during SOS, has failed to reduce to the SOS travel distance tolerance (+/-) or smaller within the SOS_P detection delay time (set by parameter). The screen displays the name of axis of this error. *If the conditions of two or more SOS -related alarms are met at a time, the notification priority order is as fol- lows: SOS position deviation error > SOS travel distance error > SOS speed error. Remedy Refer to the corrective actions of "SOS speed error" for how to cancel this error. If the SOS travel distance tolerance (+/-) (set by parameter) is smaller than the assumption, change the setting and turn OFF and ON the power. If the SOS_P detection delay time (set by parameter) is shorter than the assumption, change the param- eter setting.
