Can Your Legacy Pacific Scientific Servo Equipment be Repaired?

servo amp repairsIn 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.Pacific scientific servo drive

How To Tell The Difference Between a Servo Controller and a Servo Drive or Amplifier?

servo amplifier repairsHave you ever noticed that the terms servo controller, servo drive, and servo amplifier are often used interchangeably?  This can be confusing!

Here is the explanation in very basic terms:

  • Technically, the Servo Drive (also called a Servo Amplifier) provides power to the Servo Motor. The Servo Controller provides the specific command to action. For example: Move 10 feet at a rate of 20 feet per minute. The Servo Amplifier takes that signal and provides the necessary power for the necessary time to accomplish that task. It does this while constantly monitoring the feedback from the Encoder. It has enough onboard control circuitry to interpret control and feedback signals.
  • Here’s where it gets a bit trickier – the Servo Amplifier and Servo Controller are sometimes incorporated into ONE device. This is likely the reason why these two terms get interchanged. Generally, they are independent units – one for control, and one for power and feedback.

REAL LIFE EXAMPLE:

For example, this recently repaired Anilam servo amplifier SA 301A  (Drive) provides power to multiple servo motors (multiple axis).anilam servo amplifier repairs

 

 

 

The above Anilam servo amplifer (Drive) is connected to this repaired Anilam controller CC 516F  that provides the commands for each axis used.anilam servo controller repairs

 

 

Now that we’ve cleared that up, you might have more questions!

What if they get damaged? Are they Repairable?

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.

Are Your Servo Controllers Repairable?

servo controller repairsSmall yes, but oh so important! That’s your servo controller! What are your options if your servo controller stops functioning during machine operation? Are your servo controllers repairable?  Is replacement the answer?  It all depends!

REAL LIFE SITUATION ON THE PLANT FLOOR:

Our customer, an aircraft manufacturing contractor, found themselves in this very predicament. Their waterjet system was down due to a failed servo controller. Would they need to replace their equipment? Or were repairs possible? The good news, as is often the case, repairs WERE possible. Their Copley Controls 800-1689 servo controller was making loud noises before it failed after about 600 hours of operation. Aging components were the main cause of the failure. With the replacement of all seven capacitors, thorough cleaning and testing, the controller was back in action! This was a great relief and cost saver for our customer!

What other failures are typical in these types of servo controllers?
  • Over voltage alarms/machine will not move the axis the drive controls
  • All LED’s out
  • No power
What kind of repairs are typically required to get these units back in action? This can vary a great deal depending on the age and environment but here are a few common causes:
  • Bad or weak capacitors
  • Bad MOSFETs
  • Bad PWM

Do you have questions or concerns about your servo controller, 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 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.

What Have We Done Lately – Mitsubishi Repairs!

Mitsubishi fork lift controller repairsIn 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!

REAL LIFE PLANT STORIES: What If Your Industrial Electronic Equipment Gets Damaged During a Move?

servo controller repairs“I need this machine in the worst way! We have been told there is power coming in but none going out. We need this repaired and returned ASAP!”

That was the desperate call from our sheet metal fabricator customer. The machine in question had a damaged Gettys servo controller 11-1011-02 – the result of a jarring cross-country move.

Anyone who has ever moved their entire plant, or even a single piece of delicate equipment, knows it’s very difficult to avoid damaging vibrations during the move. Professional industrial movers can save you a lot of headaches and money! But what if your equipment DOES get damaged while moving, like this customer? Assuming your equipment didn’t literally fall out of the back of a moving truck, it can usually be repaired!

In this case, the move-damaged Gettys controller was entirely repairable.  This was true, even though it was not only damaged but also obsolete. Damaged and aging components were desoldered, removed and tested. After locating the needed obsolete parts (yes, sometimes Ebay comes in handy!), we replaced a reed relay, op-amp ICs and two regulator IC as well as reflowing damaged traces. After a thorough repair and cleaning, the unit tested successfully!

The Outcome

Good news!  The results were a fully functional controller shipped out and the desperately needed equipment is now back up and running! And we have a happy customer: “Happy to report the drive is working correctly. I cannot thank you enough. God Bless!” – J.A.
