Code 585: CABLE MIS-CONNECTED
Issue Description & Safety Warning
The Mazak Mazatrol Matrix CNC has triggered a critical CABLE MIS-CONNECTED 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
Type of error: G — External I/O unit (malfunction of external I/O unit) Stopped status: L — Operation continued Clearing procedure: S — Press clear key Display colour: Blue Cause: This message implies incorrect cable connection between the host system and the NC unit or implies a power-off status. Action: - Check if the DNC cables are correctly connected. - Check if the host system is turned on and ready for data transmission/reception. There may be cases that although a DNC option is provided, DNC itself is not to be used for the time being and thus the DNC cables are not yet connected. If this is the case, then set the appropriate parameter (DNC26, bit 1) to OFF (0). This will clear the alarm display.
