Fanuc alarm PS0203: PROGRAM MISS AT RIGID TAPPING
PS alarm (program/operation) · Fanuc 0i-D
What it means
The rigid-mode M code (M29) or the S command was positioned incorrectly in the program for rigid tapping. M29/S must be commanded in the correct sequence before the tapping cycle block.
Likely causes
- M29 placed after the G84 block
- S commanded in the same block incorrectly
- Non-rigid M code used where M29 required
