700035 — Alarm 700035 (Spindle positioning to unclamping position timeout) Diagnostic Tree

This alarm code (700035) is not found in the uploaded standard Siemens source manuals. The 70xxxx series alarms in the NC/PLC interface are typically machine builder (OEM) specific PLC alarms (the 'Spindle positioning to unclamping position timeout' message indicates that the spindle failed to reach the required orientation position for tool change within the specified time). Please check the spindle mechanics (binding) and the orientation sensor (encoder), and consult the machine manufacturer's documentation if the issue persists.
