Fanuc Alarm 029 (or PS029) ILLEGAL OFFSET VALUE
Fanus Control Model: Series 21 / 21i (Model A, B, & C) and modern controls like the 30i / 31i / 32i series
Description
Any value in the Tool Offset or Work Offset that is outside the specified range of the machine.
Fanuc parameters have a limit on how much offset you can give. If your value exceeds this limit, this alarm will occur.
How to Fix Alarm
After pressing the OFFSET button on the control panel, check the value of the tool or work coordinate (G54, G55, etc.).
If there is a large number or an incorrect decimal, correct it. For example, if the machine limit is 5mm and you have written 50mm, correct it.
