Fagor alarm 1042: Wrong parameter value in canned cycle

What it means

While defining a turning/milling canned cycle, one parameter received a value outside its admitted range - typically a negative or zero value where only positive values are valid (e.g., depth of cut C, step J, relief B). The CNC validates parameters at cycle execution and aborts.

Likely causes

• negative sign typed in a positive-only cycle parameter
• parameter computed by variables ended up zero/negative at runtime
• cycle template filled with swapped parameter values
