Error codes from a CNC machine control indicate a malfunction or failure of an electronic component. Bad ports, low voltage, irregular current, faulty RAM or rising temperatures could trigger an alarm, and the servo drive, spindle amplifier, combination unit (SVPM) or power supply may be at fault. Understanding these error messages is crucial for maintaining efficient production.
