Code 700031: Tool live management error (Siemens)
Issue Description & Safety Warning
The Chiron Siemens-Control CNC has triggered a critical Tool live management error (Siemens) 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
An internal tool management acknowledgement to the „NCK“ has been interrupted by an error and not realised correctly. Either „Reset“ or „Emergency Stop“ was actuated during the tool changing procedure (resaving of tool data). The „Changer up/down“ with „Tool change manual“ or „SE functions“ procedure was interrupted. (Reset, Emergency Stop etc.) The asynchronous resaving of tool data from the magazine to spindle (or vice versa) was thus not realised correctly. A spindle tool was defined, but the tool is not in the tool table. The tool change procedure is stopped. 1. Moving tool changer to home position 2. Press the [RESET] key or [Lamp test]. Message is cleared. A spindle tool should be defined which is in the tool table if the message 700060 „Spindle tool not defined“ is displayed.
