Below is a product video for a 6FC5210-0DF22-2AA0 Siemens PCU unit which we have in stock and ready to ship. This is a Siemens control unit with software set to run a CNC system. We have a video showing the booting up of a similar PCU 50 Siemens unit on a blog post here where we show one of these units powering up. They are basically a computer with an operating system loaded on that you can hook up to a display, keyboard, and mouse to get booted up and programming your system. Visit MRO Electric and Supply’s website for more parts from Siemens. For any questions email sales@mroelectric.com or call 800-691-8511.
Siemens 6SN1118-0DJ23-0AA0 Control Card – Product Video
Here is a video of one of the Siemens 6SN1118-0DJ23-0AA0 Control Cards that we have in stock. This is a control card for a Siemens Simodrive system, and would be inserted into a Simodrive power module such as a 6SN1123-1AA00-0EA1. We occasionally have people call in to order just the control card or just the power module, not realizing that they are two separate units that are sold separately. When deciding that you have an issue with one of these, make sure you test both the power module and the control card and order accordingly. The control cards can be used in multiple power modules so there is not one particular setup for installing one of these. If you are replacing the control card, you should also test the power module before replacing the control card because you can end up damaging the replacement 6SN1118-0DJ23-0AA0 control card if it is installed in a faulty power module.
The 6SN1118-0DJ23-0AA0 unit in this video has been fully refurbished, retested, and repackaged in our own packaging. We have plenty of all of the different Simodrive control cards in stock, so if you’re looking for a similar unit just give us a call at 800-691-8511 or email sales@mroelectric.com for a quote. The individual parts page for this unit is here, hopefully this helps and if you need anything else please let us know.
Fanuc A06B-0075-B503 Motor Product Video
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.

Modicon 140CPU43412A CPU Product Video
We currently have both new and refurbished 140CPU43412A CPUs in stock, fully tested and ready to ship out same day if need be. This Modicon 140CPU43412A CPU is one of the more popular CPUs in the Quantum Series from Schneider Electric/Modicon.
Just as a side note, we often get questions as to what the differences between Schneider Electric, Modicon, Square D, and Telemecanique are. Modicon, Square D, and Telemecanique were all bought by Schneider Electric over the years and their products are all now manufactured by Schneider. A full history of the Schneider Electric acquisitions is available on Wikipedia here.
Back to the CPU, if you are looking for the general description or the technical specs, here is a link to the PDF listed on Graybar’s website. The predecessor to this CPU is the 140CPU43412, where the 140CPU43412A is functional identicial to the non-“A” version, the only differences being that if you are using multiple units in a hot standby system you need to use either two 140CPU43412 units or two 140CPU43412A units, and the “A” version has a unique flash executive which isn’t interchangeable. We have another blog post detailing the differences here.
Below we have a video of the product itself to help with anyone who is looking for replacement. For pricing or any other questions give us a call a 800-691-8511 or email sales@mroelectric.com.
Product Video – Fanuc A06B-6066-H008 Servo Amp
To highlight some of the products that we have in stock and service we’ve decided to start uploading videos of the individual products.
