Fanuc alarm PS0031: ILLEGAL P COMMAND IN G10
PS alarm (program/operation) · Fanuc 0i-D
What it means
During programmable data input with G10, the P address is invalid: a required setting address (P/R etc.) was not specified, an irrelevant address was given for that L number, or the sign/range of the value is out of bounds. Address requirements vary with the G10 L group number.
Likely causes
- Wrong or missing P address for the G10 Lxx group
- Value out of range or wrongly signed
- Mixed-up addresses copied between different G10 formats
