Error 0090 · CNC 8055 M · CNC 8055 T
Message: Square root of a negative number.
Detection
While editing at the CNC or while executing a program transmitted via DNC.
Cause
An operation has been programmed which involves the calculation of the square root of a negative number.
Solution
Only the square root of numbers greater than zero can be calculated. When working with parameters, that parameter may have already acquired a negative value or zero.
Verify that the parameter does not reach the operation with that value (0).
