Code 116: Spindle Orientation Fault
Issue Description & Safety Warning
The Haas VF-Series CNC has triggered a critical Spindle Orientation Fault 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
Spindle did not orient correctly. This is either a vector drive problem or a mechanical problem on machines without a vector drive. During a spindle orientation function, the spindle is rotated until the lock pin drops in; but the lock pin never dropped. Parameters 66, 70, 73, and 74 can adjust delays and spindle orient speeds. This can be caused by a trip of circuit breaker CB4, a lack of air pressure, or too much friction with the orientation pin.
