Fanuc alarms are essentially the FANUC CNC producing errors due to hardware, software faults or the execution of programs. There are many different alarms produced on the many series of Fanuc controls from the late 1970’s to current drives and controls.
System Alarms
Drive Alarms Servo, Spindle and PSM
Pulse coder (Absolute APC) & (Serial SPC) alarms
Overtravel alarms (OT)
Overheat alarms (OH)
Program errors (P/S alarm)
Being involved with Fanuc for decades we have always thought better to list SYSTEMS, drives, then function errors which can be illegal program codes, etc.
Below is a fanuc alarm codes list by drives and system. As well plan to do servo alarms by Fanuc fault codes on the servo and the control systems.
Fanuc Drives & ALPHA module alarms:
- FANUC ALPHA spindle module & aiSP alarms
- FANUC ALPHA Servo module & aiSV alarms
- FANUC ALPHA Power supply & aiPS alarm codes
- Fanuc DC Axis alarms
- Fanuc AC Axis alarms
- Fanuc AC spindle drive alarm codes (S / P / I Series)
- Fanuc Serial spindle servo unit alarm codes
Fanuc System alarms:
- Fanuc 0, 0M, 0T alarm codes.
- Fanuc 6, 6M, 6T alarms
- Fanuc 10 & 11 alarms – 10 & 11 master pcb error codes
- Fanuc 15 alarm codes
- Fanuc 16 / 18 / 20 / 21 alarms, errors and system fault codes.
- Fanuc 16i / 18i / 21i alarms and error code.
Error codes and alarms produced on Fanuc amplifiers, system, power supply units and modules, I/O racks operating the PLC side of the CNC are extensive. They do take time to understand and unfortunately our lists will never negate the need for a quality CNC maintanence engineer to visit site and diagnose and solve faults on your machine(s).
