What is a FANUC 414 Servo Alarm?
A FANUC 414 servo alarm is generated by the CNC when it detects that an amplifier has a high current alarm 8, 9, or A. To determine the exact cause, you must go through the process of elimination. The high current alarm may be caused by the servo drives, amplifiers, modules, motor and/or cables.
In some instances, this alarm may indicate a short to ground. The short is causing too much current to flow through the power module inside the amplifier and will eventually cause it to break.
Here is the FANUC 414 Servo Alarm message:
Alarm Code | Message | Description |
414 | SERVO ALARM: n–TH AXIS – DETECTION RELATED ERROR | N–th axis (axis 1–8) digital servo system fault. Refer to diagnosis display No. 200 and No. 204 for details. Look at the servo amplifier for alarm code. |
How to Diagnose a FANUC 414 Servo Alarm:
Step 1 - Access the electronics cabinet with the power on (WARNING: Hazardous voltage inside).
Step 2 - Look for the amplifier unit displaying either FANUC servo alarm 8, 9, or A on the seven segment display.
Step 3 - Alarm 8, 9, and A are all the same problem. However, the different alarms identify which amplifier axis the alarm exists on.

Code | Message | Description |
Alarm 8 | Abnormal current alarm (L axis) | Located below the logic board, Alarm 8 indicates an abnormal current in the first axis on the amplifier which is labeled (L). |
Alarm 9 | Abnormal current alarm (M axis) | Located below the logic board, Alarm 9 indicates an abnormal current in the second axis on the amplifier which is labeled (M). |
Alarm A | Abnormal current alarm (N axis) | Located below the logic board, Alarm A indicates an abnormal current in the third axis on the amplifier which is labeled (A). If your amplifier only controls two axes, your CNC should never display an Alarm Code A. |
Step 4 - Turn on the main breaker of the machine and leave the CNC off.
a. If FANUC servo alarm 8, 9, or A appears when the CNC is off, disconnect the feedback connector to the amplifier axis indicated by the alarm and turn on the main breaker with the CNC off again.

i. If no alarm appears, there is an issue with the feedback cable or the pulse coder.
ii. If alarm 8, 9, or A appears with the feedback cable disconnected, the amplifier is most likely faulty and needs to be replaced.
b. If the alarm ONLY appears when the CNC is turned on, you need to troubleshoot the drive, motor, and power cable.
Step 5 - Disconnect the four motor leads from the bottom of the amplifier.
Step 6 - Turn on the CNC and release any emergency stop condition (if you’re removing the motor power with a vertical axis, physically prop up the axis or else it will fall when the emergency stop and servo motor brakes are released).
Step 7 - If an alarm 8, 9, or A still appears, the drive is probably faulty and needs to be replaced.
Step 8 - If an alarm doesn’t appear, the motor and/or power cable may be faulty and needs to be diagnosed.
Step 9 - With an ohm meter, check for shorts in the motor by measuring leg-to-leg and leg-to-ground on all three legs. An ohmmeter will tell you if your motor is shorted. Leg-to-leg readings should be low, but consistent, on all three legs. The leg-to-ground readings should be open (OL) on all three legs-to-ground.
Step 10 - With a megger, check each leg-to-ground. A megger will tell you if your motor is grounded. The reading should show infinity (or 500 MEG and above) at the 1000V setting. Check all three legs-to-ground because the problem can be in the power plug/terminal box of the motor or the power cables going from the drive to the motor.

What is a FANUC Spindle Drive Alarm 01?
A FANUC Spindle Drive Alarm 01 Code is generated by the CNC when it detects that the inside temperature of the drive motor is higher than the specified temperature. Here is the FANUC Alarm 01 message:
Alarm Code | Message | Description |
01 | Motor Overheat | The Alarm Code 01 detects internal motor temperatures exceeding the specified temperature. |

How to troubleshoot a FANUC Spindle Drive Alarm 01 Code
Step 1 - If a FANUC Alarm 01 Code is issued during cutting:
(a) Investigate the cooling state of the spindle motor.
- If the cooling fan is stopped, check the power supply. Otherwise, replace the cooling fan. The technicians at TIE can help repair or replace the cooling fan on your spindle drive.
- If your spindle drive utilizes a liquid-cooled motor, search for issues with the cooling system.
- Make sure the ambient temperature of the spindle motor is within the appropriate range specified for your unit.
(b) Check the short-period rating. If this alarm is issued when the load meter fluctuates in a limited range, the short-rating period is being exceeded and the load needs to be reduced.
Step 2 - If the Spindle Drive Alarm 01 is generated under a light load:
(a) Make sure the frequency of acceleration/deceleration does not exceed the continuous rating.
(b) Check the specific parameters of the drive motor and make sure they are correctly applied.
Step 3 - If the Alarm 01 is issued when the motor temperature is low:
(a) The spindle motor feedback cable may be faulty. Make sure the CN2 cable is plugged into the CN2 connector. If the CN2 cable is appropriately connected and still registering an Alarm 01 when the motor temperature is low, replace the cable.
(b) Check the control printed circuit board or spindle amplifier. If it is faulty, T.I.E. can replace the control PCB or spindle amplifier to get your CNC machine back up and running.
(c) Investigate the internal thermostat of the motor. If it is faulty, the entire motor may need to be replaced.
