Description
Minus Sign - is written in a place where it is not allowed. This alarm can sometimes be caused by a logical error in programming or a mistake in data entry. For example, if you add a minus sign to the number O (such as O-1234) or a minus sign to a parameter that only accepts positive numbers, the system will give this error.
How to Fix Alarm
The block (line) where the cursor is stopped must be checked. Check if there is a minus sign with the G-code, M-code, or any T-code (tool number).
