Fanuc alarm: 416,426,436,446,456,466,476 - SERVO ALARM: n-th AXIS - DISCONNECTION

CNC Description: Position detection system fault in the n-th axis pulse coder (disconnection alarm).
Fanuc alarm: 416,426,436,446,456,466,476 - SERVO ALARM: n-th AXIS - DISCONNECTION

Fanuc alarm: 409 - SPINDLE ALARM DETECTION

CNC Description: A spindle amplifier alarm occurred in a system with a serial spindle. The alarm is indicated as
Fanuc alarm: 409 - SPINDLE ALARM DETECTION

Fanuc alarm: 410,420,430,440,450,460,470 - SERVO ALARM: n-th AXIS - EXCESS ERROR

CNC Description: The position deviation value when the n-th axis stops is larger than the set value. (Note) Limit value must be set to parameter for each axis.
Fanuc alarm: 410,420,430,440,450,460,470 - SERVO ALARM: n-th AXIS - EXCESS ERROR

Fanuc alarm: 411,421,431,441,451,461,471 - SERVO ALARM: n-th AXIS - EXCESS ERROR

CNC Description: The position deviation value when the n-th axis moves is larger than the set value. (Note) Limit value must be set to parameter for each axis.
Fanuc alarm: 411,421,431,441,451,461,471 - SERVO ALARM: n-th AXIS - EXCESS ERROR

Fanuc alarm: 413,423,433,443,453,463,473 - SERVO ALARM: n-th AXIS - LSI OVERFLOW

CNC Description: The contents of the error register for the n-th axis exceeded the power allowed. This error usually occurs as the result of an improperly set parameters.
Fanuc alarm: 413,423,433,443,453,463,473 - SERVO ALARM: n-th AXIS - LSI OVERFLOW

Fanuc alarm: 403 - SERVO ALARM: 3, 4TH AXIS VRDY OFF

CNC Description: 3-axis, 4-axis servo amplifier READY signal (DRDY) went off.
Fanuc alarm: 403 - SERVO ALARM: 3, 4TH AXIS VRDY OFF

Fanuc alarm: 404 - SERVO ALARM: n-th AXIS VRDY ON

CNC Description: Even though the n-th axis (axis 1-8) READY signal (MCON) went off, the servo amplifier READY signal (DRDY) is still on. Or, when the power was turned on, DRDY went on even though MCON was off. Check that the axis card and servo amplifierr are connected.
