Fanuc 332 - Peck drilling data error
Alarm 332 occurs during peck drilling cycles (G73, G83) when the control detects invalid parameter values or missing required data. Common causes include improper Q value specification for peck depth, conflicting R-plane and Z-depth values, or omitted mandatory parameters in the drilling cycle command.

Fanuc 332 - Peck drilling data error
PECK DRILLING DATA ERROR
Fanuc PS program alarm 332: PECK DRILLING DATA ERROR. This alarm is triggered by an illegal or incorrectly formatted command in the part program, or a programming condition that the Fanuc control cannot execute.
Root Cause Summary
Alarm 332 occurs during peck drilling cycles (G73, G83) when the control detects invalid parameter values or missing required data. Common causes include improper Q value specification for peck depth, conflicting R-plane and Z-depth values, or omitted mandatory parameters in the drilling cycle command.
Safety
- Verify corrected program or parameters before resuming machining
Causes and Fixes
- 1
Locate the G73 or G83 peck drilling cycle line in the program that triggered the alarm.
- 2
Verify that Q parameter is present in the block (e.g., G83 Z-2.0 R0.1 Q0.25 F10.0).
- 3
Ensure Q value is positive and greater than zero. Typical range is 0.01 to several millimeters/inches depending on application.
- 4
Confirm Q value is smaller than the total drilling depth (Z - R plane distance) to allow multiple pecks.
Q value too large relative to total depth will cause single peck operation or errors on some controls.
