A06B-6058-H005: Beyond the User Manual

Generally, Fanuc AC servo motors, like the A06B-6058-H005, have no parts that wear off or that must be replaced periodically, unlike DC servo motors, which have brushes that must be replaced. However, you should perform period maintenance for servo motors so as to keep their initial performance as long as possible and to prevent breakdowns. AC servo motors have precision sensors — their incorrect use or damage caused during transportation or assembling can result in breakdowns or accidents.

It is recommended that you inspect servo motors periodically, and of course we offer a 12 month warranty on all Fanuc products purchased from MRO Electric.

Receiving and Keeping the A06B-6058-H005

When you receive a A06B-6058-H005 module from MRO Electric, make sure that the motor is exactly the one you ordered, in terms of model, shaft, and sensor specifications, and make sure that no damage has been caused on the motor. Servo motors should be kept indoors as a rule. The storage temperature range is -20 to +60 Celsius. Do not place or install AC servo motors in a place where it is extremely humid and dew is prone to form, where there are steep changes in temperature, where there is constant vibration, or there is lots of dust and trash. Constant vibration may cause damage to the shaft bearings.

Daily Inspection Procedures

Before starting operation, or periodically (once a week or month), you should inspect the AC servo motors for vibration and noise, outside damage, stains and smudges, overheating.

Check the motor for abnormal vibration by hand, and noise by ear when the motor is not rotating, rotating at low speed, and accelerating and decelerating.

Check the Pulsecoding cover (read plastic) for crevices and the motor surface (black coating) for scratches and cracks. If you find a crevice on the Pulsecoder cover, you should replace it. If there is a scratch or a crack on the motor surface, the user should repair it by himself as required. If coating has come off, dry the portion of interest or the entire surface and coat it with paint for machines such as urethane paint.

Check the motor surface and bolt holes for oil or cutting fluid. Wipe off oil and cutting fluid on the surface periodically. Oil or cutting fluid can damage the coating by chemical reaction, possibly leading to failure. Also check how such liquid leaks onto the motor, and repair if needed.

Check to see if the motor is too hot during normal operation. Attach a thermolabel on the motor surface and check it visually to see if the motor becomes too hot during normal operation.

If you experience a system failure due to a Fanuc C series servo amplifier, (A06B-6066-H002, H003 etc.) you may feel like your only option is to replace it with the same exact unit. However Fanuc also offers the α series servo amplifiers which features improvements over the C series. In most cases you can replace your C series servo amplifier with the α series servo amplifier that has the identical final four numbers of the C series model number. The chart below outlines this:

The advantages of replacing your C series amplifier with an α series amplifier are:

• A built in power supply
• A second interface, type B, as well as the more conventional type A interface
• Updated power device, intelligent power module, to reduce power loss and increasing reliability

α series amplifiers are also designed with the same dimensions as the C series so that you can install them into your current system easier.

Go to our website to check out our selection of C series and α series FANUC amplifiers.

Here is a video of one of the many Fanuc AC motors that we have in stock,  and this one is the Fanuc A06B-0075-B503 Motor. This is an AC Fanuc motor that has a brake and a keyway already installed. At 22.85lbs and 8.1 X 15.3 X 6.5 inches, this is one of the smaller motors that Fanuc manufactures. The motor in the video is brand new and comes in the original factory packaging, we only took it out of the packaging to get a video of it. If you are looking to get your old motor repaired, we do also offer a repair service for these AC motors with a standard turnaround of 3-5 days.

If you’re also trying to figure out if your motor is bad you can check out this other blog post that we put up to show some basic steps for testing your motor. The page is here, it has some useful steps to go through to confirm that your motor is causing your problem.

MRO Electric and Supply maintains a comprehensive stock of new and used FANUC CNC and FANUC Robots parts. If you need a FANUC replacement part, please call 800-691-8511 or email sales@mroelectric.com.
