Benefits of Upgrading Your HMI to LCD Technology

Human Machine Interfaces, or HMI’s, are used extensively throughout the world to control and monitor automated machinery.  These devices provide touchpad and visual interaction to control manufacturing processes and perform daily tasks.  One of the most recognized HMI devices is the Automated Teller Machine (ATM).  These ATM devices intuitively interface with users through a keypad and monitor to readily transact bank deposits and dispense cash withdrawals.  They provide reliable 24-hour access to our daily banking needs.

Various HMI devices are common throughout industry.  Many older HMI devices contain the original Cathode Ray Tube (CRT) monitor technology.  This older technology burdens the users and owner with several disadvantages:

  1. High Energy Consumption – The CRT technology is not considered energy efficient.  It requires more power to operate than the newer LCD technology.  CRT screens consume 3 – 4 times the energy when compared to the LCD screens.
  2. Expensive to maintain – CRT repairs are becoming more specialized and expensive as the workforce transitions to the newer technologies.
  3. Obsolete Components – CRT technology is outdated and beyond its life cycle.  Components required to support repair are becoming obsolete and expensive if available.
  4. Avoid costly new operator interface packages – MRO upgrades to LCD technology maintain the interface packages with your existing equipment (frames, communication connections, power sources, etc.).  Updated HMI’s from MRO are plug-n-play.
  5. Better Reliability – Heat generated by the CRT technology often shortens the life of the electrical circuit components.  CRT monitors tend to have a life of 18,000 to 20,000 hours.  LCD monitors provide more than 100,000 hours life.
  6. Clarity of Picture, Crisp Image – LCD’s make the screen burn often associated with CRT’s a thing of the past.  LCD image display is much clearer for the operator and will not fade.

MRO provides an HMI service to update your old CRT displays to LCD technology and new keypads.  This approach is a low-cost upgrade to superior technology with no risks. Visit our repair page, call us, or email us for an instant quote on fixing, swapping, or purchasing your new HMI device.

Determining if your FANUC Motor has a Keyway

There are a couple ways to figure out if your FANUC motor has a keyway:

The first is if you can visibly look at the end of the shaft and see the holes on the end of the coupling. If your shaft has one hole at the end in the very center, it is a slick shaft. If the shaft has three holes in a line, that means you have a keyed shaft.

Another way to check if you have a keyed shaft without being able to look at the shaft is reading the OEM label on the FANUC motor. Your motor may have one of two types of labels on it, the first being a yellow FANUC sticker and the other being a silver G.E. FANUC sticker. All of the silver G.E. FANUC stickers on motors have a # suffix indicating a keyed shaft, except for the tag #7000 which indicates that it is actually a slick shaft. The pictures below show what each tag looks like with the # tag.

The yellow FANUC sticker is a little bit easier to determine. If the part number has the # tag at the end of it, it is a keyed shaft. If there is no # at the end of the part number, that means it is a slick shaft. Below is a picture of a yellow FANUC tag without the # tag.

FANUC Alarm Codes – A06B-6066 Drives – Alarm 5

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

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.

Proper Maintenance on your FANUC Spindle Motor can Extend its Life

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.

Setting the Sensor Gap on your Fanuc Spindle Motor

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.

Diagnosing your FANUC Current Alarm

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.

fanuc high current

  • 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.

FANUC M-Codes List for 16i, 18i, and More

M-code are CNC program instructions which help machinists and CNC programmers control CNC hardware like chuck, tailstock, quill, coolant. Here are listed M-code which are mostly used on 16i and 18i FANUC Controls.

Auxiliary Function (M Function)

When a numeral is specified following address M, code signal and a strobe signal are sent to the machine. The machine uses these signals to turn on or off its functions. Usually, only one M code can be specified in one block.

In some cases, however, up to three M codes can be specified for some types of machine tools. Which M code corresponds to which machine function is determined by the machine tool builder.

The machine processes all operations specified by M codes except those specified by M98, M99,M198 or called subprogram(Parameter No.6071 to 6079), or called custom macro (Parameter No.6080 to 6089). Refer to the machine tool builder’s instruction manual for details.

The following M codes have special meanings:

  • M02, M03 (End of Program)
    • This indicates the end of the main program Automatic operation is stopped and the CNC unit is reset.
    • This differs with the machine tool builder. After a block specifying the end of the program is executed, control returns to the start of the program. Bit 5 of parameter 3404 (M02) or bit 4 of parameter 3404 (M30) can be used to disable M02, M30 from returning control to the start of the program.
  • M00 (Program Stop)
    • Automatic operation is stopped after a block containing M00 is executed. When the program is stopped, all existing modal information remains unchanged. The automatic operation can be restarted by actuating the cycle operation. This differs with the machine tool builder.
  • M01 (Optional Stop)
    • Similarly to M00, automatic operation is stopped after a block containing M01 is executed. This code is only effective when the Optional Stop switch on the machine operator’s panel has been pressed.
  • M98 (Calling of Sub-Program)
    • This code is used to call a subprogram. The code and strobe signals are not sent.
  • M99 (End of Subprogram)
    • This code indicates the end of a subprogram. M99 execution returns control to the main program. The code and strobe signals are not sent.
  • M198 (Calling a Subprogram)
    • This code is used to call a subprogram of a file in the external input/output function. See the description of the subprogram call function (III–4.7) for details.

 

Multiple M Commands in a Single Block

In general, only one M code can be specified in a block. However, up to three M codes can be specified at once in a block by setting bit 7 (M3B) of parameter No. 3404 to 1. Up to three M codes specified in a block are simultaneously output to the machine. This means that compared with the conventional method of a single M command in a single block, a shorter cycle time can be realized in machining.

CNC allows up to three M codes to be specified in one block. However, some M codes cannot be specified at the same time due to mechanical operation restrictions. For detailed information about the mechanical operation restrictions on simultaneous specification of multiple M codes in one block, refer to the manual of each machine tool builder. M00, M01, M02, M30, M98, M99, or M198 must not be specified together with another M code. Some M codes other than M00, M01, M02, M30, M98, M99, and M198 cannot be specified together with other M codes; each of those M codes must be specified in a single block.

Such M codes include these which direct the CNC to perform internal operations in addition to sending the M codes themselves to the machine. To be specified, such M codes are M codes for calling program numbers 9001 to 9009 and M codes for disabling advance reading (buffering) of subsequent blocks. Meanwhile, multiple of M codes that direct the CNC only to send the M codes themselves (without performing internal operations ) can be specified in a single block.

M Code Group Check Function

The M code group check function checks if a combination of multiple M codes (up to three M codes) contained in a block is correct.

This function has two purposes. One is to detect if any of the multiple M codes specified in a block include an M code that must be specified alone. The other purpose is to detect if any of the multiple M codes specified in a block include M codes that belong to the same group. In either of these cases, P/S alarm No. 5016 is issued. For details on group data setting, refer to the manual available from the machine tool builder.

  • M Code Setting
    • Up to 500 M codes can be specified. In general, M0 to M99 are always specified. M codes from M100 and up are optional.
  • Group Numbers
    • Group numbers can be set from 0 to 127. Note, however, that 0 and 1 have special meanings. Group number 0 represents M codes that need not be checked. Group number 1 represents M codes that must be specified alone.
