Issue Description & Safety Warning
The Heidenhain TNC Series CNC has triggered a critical Preset compensation not possible 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
[Cause of error] You tried to run a compensation of the preset although not all the entries required for it are in the kinematic description. You can only run the preset compensation if transformations in three separate axes in the machine coordinate system are entered in the kinematic description. [Error correction] Change the number of measuring points in the cycle so that the control can run a preset compensation. If necessary, contact the machine manufacturer. [890] 10/2023
