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.

ge-fanuc

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.

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.

  • 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.

Adjustable speed drives (ASDs), or variable-speed drives (VSDs) is used to describe equipment that assists to control the speed of machinery. Usually, they are using in mechanical equipment powered by motors.

The drives offer truthful electrical motor control enabling motor speeds to be increased, decreased and maintained.

Save On Energy:

Due to energy consumption, centrifugal fan and pump loads operated with versatile speed drives are reduced. The horsepower needed to operate the fan is cut by a much larger factor if the speed of the fan is cut in thirds or in half. As everyone knows, energy savings are what machine automation professionals yearn for.

Controlled torque limit:

By using an adjustable speed drive, machinery can be protected from any damage that may occur. The specific amount of torque applied by the motor to a load is able to be fully controlled.

Controlled Starting Current:

Usually when an ac motor is started “across the line,” it takes about as seven-to-eight times to start the motor and load.

 By utilizing an adjustable speed drive, the considerably reduced starting current expands the life of an ac motor. The benefits are less wear & tear on the motor which translates to extend motor life and less motor rewinds.
Governed Stopping:

Governed stopping backs up diminish product loss because of machine-driven wear and tear attributed to shocks to the process.

Reverse Operation:

The requirement for a reversing started is mitigated in regards to utilizing an adjustable speed drive. The reason being is the output phases to the motor can be morphed electronically. Removing the reversing starter terminates its upkeep expense while also minimizing panel space.

Decreased Power Demand on Start:

To begin an AC motor across the line, one is going to need much more power compared to beginning an adjustable speed drive. This is only the case at the start because the power to run the motor at load would be the same regardless of its variable speed.

Adjustable Operating Speed:

Process automation and implementing changes in a process is allowed due to deploying an adjustable speed drive. This also enables beginning at a shortened speed and allows remote acclimation of speed by process controllers.

Removal of mechanical drive components:

By using an adjustable speed drive, the likelihood of needing costly mechanical drive components like gearboxes can be mitigated. The AC drive is able to transport the high and/or low speed required by the load with a consistent speed between the motor and load because it’s able to function with an infinite variable speed.

AC Drives vs DC Drives: Which is best for you?

What is an electric drive?

An electric drive is used to control the motion and speed of motors, robots and/or other electrical devices. Usually, a drive will have one or several electric motors. In the modern day, any control offered by these devices is often aided by software, which can help control accuracy. There are two main types of electric drives: AC drives and DC drives.  

What is an AC drive?

An AC drive stands for Alternating Current, but could also be referred to as an adjustable speed drive, adjustable frequency drive, variable frequency drive, variable speed drive, frequency converter, inverters and a power converter. Typically, they are used to control the speed of an electric motor in order to enhance the operation of numerous applications relying on electric motors, minimize mechanical stress on motor control applications, generate energy as efficiently as possible, cut down on energy usage and, lastly, optimize process control.

Also known as adjustable speed drives, inverters and power converters, adjustable frequency drives, and variable speed drives, AC drives are similar to  DC drives because an AC input is regulated to DC by simple bridge rectifiers, commonly referred to as SCRs. Because AC drives use a capacitor bank to stabilize and smooth this DC voltage, the DC output would be half cycle according to AC input phase frequency. Then, power is supplied to the motor in the output section of the drive by means of 6 output transistor or IGBT modules. Essentially, the AC input current is converted by the drive to DC and, again, converted back to AC in order to supply the motor. The current is converted twice by the drive because the AC input is either 50 or 60-hertz cycles. When the DC voltage is converted to AC again by the drive, it uses a carrier frequency of at least 2 KHZ to 100 KHZ in more complex drives. Therefore, the output current is able to be raised tens or hundreds of times without burning up the motor coil with an AC drive.

The AC motor is also able to rapidly switch speeds with zero problems because of this function. AC drives typically have numerous types of feedbacks from simple, 2-line incremental encoders, to resolvers or absolute encoders with a significant resolution that facilitates the drive to calculate motor shaft speed and angle as spot-on as possible. There is a third circuit called regeneration on a handful of larger, more powerful drives. This circuit converts the inertia of the load and motor to AC power and transfers it back to the input lines when the motor transitions from a significantly high speed to a low one, which, in the long run, would conserve on power and increase energy efficiency.

AC drives serve many different industrial and commercial applications.

What is a DC drive?

Essentially, a DC drive converts an AC drive into direct current, otherwise known as DC to operate a DC motor. The majority of DC drives use a handful of thyristors (also known as SCR’s) to craft a half cycle of DC output from a single phase AC input, also known as the half-bridge method. The more complex ones use up to 6 SCR’s to power a DC output from a 3 phase AC input, which is known as the full-bridge. Therefore, in the full-bridge method, we have 2 SCR’s for every input phase. The aspects of a DC drive are as follows: compact in size, outstanding speed regulation, broad speed range, cost-effective for medium and high HP applications, and speed changes that are derived from by increasing or decreasing the amount of DC voltage the drive feeds the motor.

Controlled by the gate input, an SCR switch is similar to a one direction switch and turns on by applying a low voltage to the gates. The drive can control the motor speed by applying the voltage to the gate at a contrasting angle of the input phase. To authenticate the motor speed and compensate if necessary, the majority of DC drives require the motor to have a tachometer as means of feedback. A tachometer is essentially a mini permanent magnet DC motor accompanied by the main motor’s shaft.

Because higher motor speed generates more voltage in the tachometer, the drive references this voltage to ensure the motor is operating at a correct speed per-user settings. More compact DC motors have a permanent magnet field while larger DC motors have a separate coil inside the motor, also known as a field, which eliminates the need for a permanent magnet in the motor. DC drives with field output typically have a more compact circuit to supply the field coil. DC drives are best used in when a DC motor exists in a safe and dry atmosphere and the use of DPG, DPG-FV, TENV, or TEFC motor enclosures is required, motor speeds are able to reach 2500 RPM, application requirements are medium or large, and starting torque is either unpredictable or greater than 150%.

What’s the difference between AC and DC drives?

When it comes to AC drives vs DC drives, DC drives are commonly considered problematic, despite their prestige for having simple circuits, providing high start-up torque, and being ideal for applications with constant speed due to the requirement of commutators and brush assemblies in their motors. These motors can become worn over time, have operational issues, and will likely require labor to preserve.

On the opposite side of the spectrum, AC drives are considered more energy-friendly and are able to endure rapid speed changes more efficiently due to their running induction motors. Often times, they have hundreds of numerous programmable parameters for secure protection. Although, because of these factors, the AC drive is more complex, modernized software is simplifying their overall use.

In previous years, DC drives were regularly utilized due to their simplicity, the majority of machine manufacturers prefer to use AC drives as of late. The complexity of an AC drive has been repeatedly simplified and fine-tuned, resulting in a plethora of advantages.

Though in the past DC drives were often utilized due to their simplicity, most machine manufacturers now prefer to use AC drives (especially for servo applications). The intricacy of an AC drive has been simplified over time and has many upper hands.

Conclusion

So which would work better for you? When it comes to AC drives vs DC drives, it’s important to keep in mind DC drives’ infamous ability to provide high start-up torque, which makes them ideal for applications that have a constant speed. In comparison, AC drives are generally more energy efficient. They also have running induction motors, and can therefore handle rapid speed changes better than DC drives.
