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.
What Is Ovc Alarm In Fanuc Robot Parts. My great deal is fast becoming only a fair deal. Now I am getting random (but becoming more often) 409 sp1-30, 414. Hi all, Anybody got alarm #436 on Fanuc Oi? When home X axis, we got alarm 500 X axis overtravel. I hit O.T Release button and Machine Ready button (in the same time), I moved X axis, the ball screw not moved and got alarm #436? Ultra-compact FANUC M-1iA Series Robot and enter a new dimension in high-speed small parts handling.With 3, 4 or 6 axes, this series of high-speed delta robots is ideal for a variety of applications requiring a maximum payload of 1 kg and a work envelope of up to 420 mm. FANUC Servo Drive & Motor Repair Common signs of malfunctioning servos include erratic operation & vibration, failure of detection circuits, blown fuses and malfunctioning OVC and HC alarms. When FANUC drives & motors have failed or are running improperly, your CNC machinery is compromised and must be addressed immediately.

O (Action 1) Check the operating conditions for the robot. Fanuc alarms, GE Fanuc CNC machine tool spare parts supply boards, power supplys, motors, any fanuc parts and repairs - The UK number one we ship world wide fast! 52 rows This alarm occurs when the n–th axis (axis 1–8) is in one of the conditions listed below.
Here is the FANUC 414 Servo Alarm message:
Alarm Code | Message | Description Bioshock infinite free mac. |
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:
Usb camera wc04 drivers for mac. 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.
Message | Description | |
Alarm 8 | Abnormal current alarm (L axis) Ihra drag racing sportsman edition pc free download. | 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. Braemar holter software. 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.

6/4/18 FANUC Technician On-Site visit
- Emergency Stop wasn't working when running LABVIEW_COM on teaching pendant
- We added the command
- $MCR_GRP[1].$machinelock=1 ;
- to the program because there was a lot of interference from the Robot servos that we were picking up on the EMG signals from Yuni's experiment. However, this disables the E-Stop. When I called Fanuc to troubleshoot the E-Stop issue, they told me there was no way to disable the E-Stop in software and we needed a technician to replace the E-Stop board. They were wrong! So, we took $machinelock=1 line out of the program and the E-Stop started working again. We'll have to shield our circuits in the future if we need to do something like this again.
- We added the command

- Joint 6 doesn't have a mark - just line up horizontally with the words down.
- If you get 'No Pulse Detected' error on a joint, then you just manually move the joint and then put it back. ????????
