Fagor alarm 1155-1163: Maximum axis limits of the * axis exceeded
CNC 8055 CNC error · Fagor 8055/8055i
What it means
A programmed coordinate lies outside the travel envelope defined by the axis machine parameters LIMIT+ (P5) and LIMIT- (P6). The CNC reacts with the full stop sequence - axis/spindle halt, enables off, analog outputs canceled, position loop opened with LOPEN=1 when applicable, and program interruption.
Likely causes
- part program coordinates beyond configured soft limits
- LIMIT+/LIMIT- values edited down after machine modification
- offsets stacking to push effective position past the envelope
Triage note: Nine-code axis-mapped range (1155 = first axis); distinct from the PLC hard-limit alarms 1200-1208.
