FANUC Alarm Codes – A06B-6066 Drives – Alarm 5

Brian Hughes Leave a comment

The following is a list of procedures to fix the Alarm 5 status on your drive:

  • If you are receiving the alarm after a fresh install of the drive, check to make sure all jumpers and wires are set in their correct position. You can find the location for these inside your user manual.
  • Make sure the drive is off. Check the resistances on the drive, and then test the voltage. If it has been powered up recently, you can then turn it on to check the voltage again. However, do not immediately turn it back off to check the resistances again. You must give it at least 30 minutes for the voltage to return to safe levels so that you can check again.
  • To check the voltage, you can test the DC voltage of the jumper attached between screws 17/18 and 19.
  • Using your ground on screw 19 and and the red lead on the other two screws, your reader should say anywhere from .003 to .006 volts.
  • To check the resistance, remove the jumper from screws 15/16 and then tighten the screws. Use an ohm reader to make sure the resistance isn’t OPEN.
  • Check the resistance between screws 17 and 18. If it is 16 ohms that is where you want it to be.

Instructions for Installing a 6055 Spindle Drive to A20B-1001-0120

Brian Hughes Leave a comment

The following is a list of instructions for installing a 6055 Spindle Drive with the A20B-1001-0120 Spindle Drive PCB:

A20B-1001-0120

Instructions:

  1. Make sure the jumpers on the new spindle PCB match the jumpers on your old spindle PCB.
  2. Remove the software chips from the old spindle PCB and install them onto the new spindle PCB.
  3. If possible, remove the NVRAM chip from the old spindle PCB and install it onto the new spindle PCB. This way you will not have to reprogram the chip as the new spindle will have the same instructions as the previous one.
  4. If possible, remove the DAC chip from the old spindle PCB and install is onto the new PCB. There may not be a DAC chip on your previous board and if that is the case do not worry about it. However if the old board does have the chip, failure to install it correctly into the new board will cause issues.
  5. Make sure to set the 200/230 voltage switch to the same setting it is on the old board. This switch also may not be on all drives.

It is very important to follow the manual and make sure that the chips and cards you are moving around are installed correctly. For instance, if you were to incorrectly install the software chips, not only would the display not show anything, you are leaving open the possibilities for a short and causing yourself even more trouble.

  2. Check to see the status of the 200/230 voltage switch on the old spindle PCB and set it to the same setting on the new spindle drive. You can locate the switch underneath the lid on smaller drives.
  3. Remove the software chip on the old spindle drive and install it into the new one.
  4. If you used a DAC chip in your old spindle, you can can remove it from your old spindle PCB and install it into your new one.

It is very important to follow the manual and make sure that the chips and cards you are moving around are installed correctly. For instance, if you were to incorrectly install the software chips, not only would the display not show anything, you are leaving open the possibilities for a short and causing yourself even more trouble.

Proper Maintenance on your FANUC Spindle Motor can Extend its Life

Brian Hughes Leave a comment

Taking care of your FANUC spindle motor and maintaining it properly is the number one way to ensure it will continue to properly run when you need it. Taking the time to understand why it is important to properly maintain your drives and motors is important in itself. Old equipment is definitely more likely fail than newer equipment, but it is entirely possible for new equipment to fail due to improper lubrication, overheating, contamination of other machine fluids, etc.

Regular Maintenance Checklist

  1. Make sure that there is no other fluids leaking into the Fanuc spindle drive from external sources.
  2. Check the installation to ensure that everything is connected correctly.
  3. Check to make sure the spindle is lubricated correctly. Both too much and too little lubrication is a bad thing so make sure to follow your manual to learn how much you need to use.
  4. Minimizing the amount of vibration on the spindle drive will prevent the dislodging or unseating of any chips/cards/wiring.
  5. Using proper impact prevention on the bearings inside the spindle will ensure the least amount of physical stress on the machine itself.

By following these steps at least once a month, you are doing yourself a service by making sure your spindle drive is maintained properly. You are saving yourself from having to get parts repaired or buying new parts, and in turn saving money and preventing downtime.

Setting the Sensor Gap on your Fanuc Spindle Motor

Brian Hughes Leave a comment

Today we will be helping you with your installation of a spindle motor. Alarms are caused by tensions issues with the belt – either being too tight or too loose in relation to the sensor. MRO Electric and Supply offers both new and refurbished FANUC Spindle amps, troubleshooting on our blog for a wide variety of parts, and repair services on any product we offer.

Steps for fixing the sensor gap

  1. Disconnect the wiring inside of the terminal box.
  2. Next take out the 4 bolts that hold the shroud/fan to the motor.
  3. Remove the screws from the cover of the sensor on the motor.
  4.  Loosen the screws holding the sensor in place until you have enough room to be able to slide a piece of paper between the gear and sensor.
  5. Tighten the 2 screws that hold the sensor in place to make sure they do not rub against each other at all.
  6. Fasten the sensor cover back to the sensor and tighten accordingly.
  7. Reattach the shroud and the fan to the motor.
  8. Configure the wiring back to what it was originally.

Now that the sensor for your FANUC Spindle amp is corrected, it should work properly. If you are still having issues we recommend looking throughout our blog as we have many articles based on helping the user troubleshoot any and all issues with their motor.

Sometimes you may not have the necessary equipment to make a diagnosis on your motor, but we do. MRO Electric and Supply offers high quality repair services on all motors so you don’t have to worry about it.

Diagnosing your FANUC Current Alarm

Brian Hughes Leave a comment

If you are getting a high current alarm on your FANUC motor, it is going to be caused by either the motor itself, the drive, or a cable. To begin the process of figuring out which alarm you are receiving you must disconnect the leads from the motor. Try powering it up and look to see if the alarm LED is lit. Fanuc alarms include the HC LED, alarm 8/9/A/B for Servo motors, and alarm 12 for Spindle motors.

  • If you no longer are seeing an alarm, the motor is most likely bad.
  • If you have powered the motor and are receiving the alarm, the issue is most likely with the drive.

Because you have disconnected the leads from the motor, you are able to use an ohm meter/megger to monitor the power levels of the cable and motor, and make sure they are working as intended. Using a megger will help you decide if your motor is grounded correctly where an ohm reader will let you know if your motor has shorted.

Using your ohm meter check for shorts both leg-to-leg and leg-to-ground on each of the legs. The leg-to-leg readings should be consistently low between every leg while the leg-to-ground readings will stay open. The megger is used to check between the leg and ground to see if the problem could be with the terminal box on the motor or any cables connected to it.

Sometimes you may not have the necessary equipment to make a diagnosis on your motor or to troubleshoot, but we do. MRO Electric and Supply offers high quality repair services on all motors so you don’t have to worry about it. Check out our website to see all available brands and parts we can service for you.
