Fanuc alarm PS0092: ZERO RETURN CHECK (G27) ERROR
PS alarm (program/operation) · Fanuc 0i-D
What it means
The axis commanded in a G27 reference-check block did not actually arrive at the reference position. G27 verifies that the programmed point coincides with machine reference; any offset between them raises this alarm.
Likely causes
- Work/machine offset applied during the G27 check
- Programmed check point not equal to reference position
- Loose coupling or lost grid causing drift
