Real Life From the Plant: C Axis drive not ok Error on Servo Drive

Well, yes and no! When we use “automation” and “robotics” in the same sentence, we are usually talking about industrial automation. That is – controlling the physical processes of manufacturing with non-human machinery.
These components together create both physical machines and control systems that automate previously human tasks in an industrial process. If this sounds futuristic, it’s not! It’s here now and here to stay.
The CNC machines we are all familiar with are common examples of automation in manufacturing. Robots, however, take things quite a bit further.
Let your imagination run wild and then double that! The automation robotics market is expanding at a fantastic rate as robots replace humans in industry in the U.S. and abroad. For example, construction robotics alone are expected to grow 450% in the next five years, and similarly medical robots. This is mind altering for many of us!
The two are typically interrelated, though not always. Robots are used to automate some physical tasks, such as in manufacturing.
These systems can be expensive but they can also save a lot of money in the long run. If you’ve invested a lot of money into your automation systems you will want them to last for a good, long time! The really good news is that this often-expensive equipment can be repaired when damaged.
Do you have questions or concerns about your robotics and automation equipment, or do you think it may need service? If it’s still under warranty, contact your OEM. If it is out of warranty, contact an independent industrial electronic repair center. They should offer free evaluations for your automation components and, if needed, a free quote for repairs. They should also provide repair reports and a good warranty that covers both parts and labor.

In a word: Yes! Legacy Pacific Scientific servo equipment CAN typically be repaired! There’s a ton of really good Pacific Scientific servo equipment still out there in manufacturing plants being used every single day. You might also be wondering what ever happened to this excellent brand. Don’t worry! The story of the Pac Sci brand isn’t mysterious or unusual.
The Pac Sci equipment brand was purchased by Kollmorgen several years ago and until 2011 kept the Pacific Scientific branding and developed a few new products under the Pac Sci name. But, when the Danaher Corporation divested itself from the Pacific Scientific Aerospace business (a separate business from the Kollmorgen business) it included the sale of the Pacific Scientific brand name and logo. This forced Kollmorgen to remove all the Pacific Scientific branding and replace it with Kollmorgen branding. Simple, just business as usual.
The good news is that your legacy Pacific Scientific equipment is usually repairable. And, also usually well worth repairing. Here’s a handy chart with a few part numbers of Pacific Scientific equipment that we frequently see in our shop for repairs with reference pricing based on previous repairs. Your repair may be slightly different depending on the amount of damage or cause of failure.

“Please rush this as fast as possible! We are down!”
We get it! We don’t like downtime either! It’s costly! Time to jump into action! Let’s get this Sanyo Denki Drive CFZ0A100DR4601 with error codes back to working order.
Mostly just that – age and dirt, lots of build up! There’s no getting around that! Testing showed numerous components had failed. To repair this drive would mean virtually rebuilding it. And that’s what our customer needed us to do!
In just a few days this unit was back to work – practically brand new again! With a two year warranty! And best of all, our mid-west US customer reported success after installing their rebuilt Sanyo Denki drive! Their CNC shop was back to work machining both gray and ductile iron! Good stuff! We love our CNC machining customers!

Have you ever noticed that the terms servo controller, servo drive, and servo amplifier are often used interchangeably? This can be confusing!
For example, this recently repaired Anilam servo amplifier SA 301A (Drive) provides power to multiple servo motors (multiple axis).
The above Anilam servo amplifer (Drive) is connected to this repaired Anilam controller CC 516F that provides the commands for each axis used.
Now that we’ve cleared that up, you might have more questions!
In this example, both of these units were repairable. Typically, the servo amplifier has a slightly higher repair success rate than the servo controller, but both are often repairable. The controller is more complicated and often contains several levels of OEM proprietary programming. The amplifier, if not catastrophically damaged, has a higher rate of repair success. It is always best to get a qualified industrial electronic repair service to evaluate your damaged servo amplifiers (drives) and servo controllers when considering whether to repair or replace.
Do you have questions or concerns about your servo controller or servo amplifier, or do you think it may need service? If it’s still under warranty, contact your OEM. If it is out of warranty, contact an independent industrial electronic repair center. They should offer free evaluations for your servo controller and, if needed, a free quote for repairs. They should also provide repair reports and a good warranty that covers both parts and labor.

Small but mighty, servo drives are critical players on the industrial playing field. These drives are common in CNC machining, factory automation, and robotics . The Teknic SST-1500-561 servo drive is a frequent flyer – meaning there are a lot of them out there working hard (see photo). If your drive faults out you will know it! Production pretty much comes to a stop!
These Teknic servo drives are good, solid equipment. But, like anything getting hard use in a harsh environment, these drives eventually break down. What should you look for? What should you expect? Here’s some answers:
Here’s are some common failures for these drives. Do any of these sound familiar?
That all sounds like major frustration on the plant floor, but there’s a fix for that! These Teknic drives are usually repairable for a reasonable cost. The repair cost is usually less than it would cost to buy a new one or refurbished one.
Typically you will find aged and blown components inside, along with trace and solder damage. Occasionally this type of damage may be visible to the naked eye. More often it requires testing to find which components are blown and which are about to go next which is an important part of a good repair!
These servo drive problem descriptions give you the picture – recurring component failure. Typically, the culprits are the capacitors, mosfets, regulators, ICs, and IGBTs. A thorough testing, cleaning and replacement of blown and aging components can bring these Teknic SST-1500-561 servo drives back to life quickly.
Do you have questions or concerns about your servo drive, or you think it may need service? If it’s still under warranty, contact your OEM. If it is out of warranty, contact an independent industrial electronic repair center. They should offer free evaluations for your servo amp and, if needed, a free quote for repairs. They should also provide repair reports and a good warranty that covers both parts and labor.
Repair of quality industrial equipment like this Teknic servo drive can be a great way to save money and time, as well as be environmentally responsible. If your Teknic SST-1500-561 servo drive needs repairs, we can help!

In our experience, Mitsubishi industrial electronic products are pretty great products. Even older, legacy Mitsubishi products are usually WELL worth getting Mitsubishi repairs.
Many of our ACS customers have legacy Mitsubishi products in their plants and shops. Lately, we’ve had lots of damaged or malfunctioning Mitsubishi industrial electronics in our shop for repairs– servo amps, inverters, operator panels, circuit board assemblies, servo drives, PLCs, controllers, and power supplies – just to name a few!
Why so many? No, not because they are all failing at once! More likely just because there are SO many good industrial electronic Mitsubishi products out there in use. And our customers know the value of maintaining their equipment. These units may no longer be under the OEM warranty, but they are also nowhere near needing to be replaced. They are still perfectly good!
Electronic repairs and refurbishing are a great way to keep good, strong Mitsubishi and other equipment in place. This can potentially save you a ton of money over buying NEW equipment that could be better spent elsewhere in your plant!
So what have we done lately?
Here’s a few examples of successful electronic Mitsubishi repairs that have arrived on our docks for lately!
Mitsubishi Operator Control Panel E-1061 – arrived with a broken screen, bad battery, bad IC and a lot of dirt/wear and tear all of which was replaceable/repairable!
Mitsubishi Servo Drive MDS-B-V2-4520 – arrived making noise in the z axis which kept getting worse and alarming out with an overcurrent Z alarm. This very dirty unit was full of weak and bad components including all of the capacitors, IGBT, and heat sinks – all replaced.
Mitsubishi PLC FX0S-14MT-D12SS – this damaged PLC required new capacitors, driver ic, resistors, and a dc to dc converter
Mitsubishi Power Supply MDS-B-CV-185 – damaged power supply arrived with a voltage problem, 41 alarm, and flashing LEDs; intermittent current – altogether this successfully repaired power supply needed replaced resistors in internal contactor circuit, replaced capacitors on the control board plus replacement of 7 other capacitors and replacement of broken leads that were not making contact.
Mitsubishi Controller F9421500 – this sturdy but damaged controller arrived covered inside and out with grease and dirt with power problems and the ready light not flashing. Repairs needed included replacements for all of the capacitors, diodes, repair of cracked solder joints, plus a thorough cleaning/degreasing – which every unit gets!
Knowledge is Power
At ACS we believe knowledge is power. If you are searching for a repair center for your damaged industrial electronics check first to see if your equipment is still under warranty. If it is still under warranty contact the OEM about repairs. If it is out of warranty, contact an independent industrial electronic repair center to find out if they are a good fit for your company and your particular repair needs. They should offer free evaluations for your damaged equipment and, if needed, a free quote for repairs (no bench fees!). They should also provide repair reports if requested and a good warranty of at least one year (more would be better!) that covers both parts AND labor.
