Drive Repair for the Professionals

Regardless of the machinery or application, a drive functions as one of the main parts of the entire system. Keeping a drive operational and working properly requires routine maintenance and attention.

When a drive begins to malfunction, there are a variety of factors which can be at work. The main electrical source might be delivering improper voltage.  External problems such as an aging motor or a physical issue with the machine that can contribute to decreased performance and lead to drive failure.

Other sources include intense vibrations, accumulated contaminants, and excessive heat. Regardless of what’s causing the problem, failed drives cut down your productivity and profit. 

ACS Industrial Services Electronic Repair can evaluate your drive and provide an accurate quote so you can consider having it repaired versus the more expensive replacement of the drive.

Drives We Service

Since 1999, ACS has been able to meet even the toughest repair challenges, with over 26,000 repairs completed since we opened our doors. 

Spindle Drives

Spindle drives can be the hardest working drive on your machine. A spindle drive is responsible for rotating the tool or the part that is being produced. In this regard, it is performing its duty more often that the axis Servo Drives.

Servo Drives

Servo Drives, or Axis Drives, are responsible for moving the machine to the proper positions necessary for the machine to accomplish its mission.  The servo drive receives feedback and control signals to determine the proper output to the motor relating to speed, torque and distance.

Variable Frequency Drives

A variable frequency drive (VFD) is designed to vary the Speed of an AC Motor by varying the frequency and voltage to the Motor.  It is the workhorse in Compressor and Pump systems. Generally, they are used to power 3 Phase Induction Motors, but they have other applications, as well.  They come configured in either AC-AC (Input-Output) or DC-AC (Input-Output).

DC Drives

The DC drive you use is there to supply voltage to the motor so it can operate at a desired speed. When the drive output varies, the motor speed varies proportionately.  Usually, a DC Drive converts AC Voltage into DC Voltage to run the motor.  

Drive Repair

Our expert technicians know what problems to look for no matter what type of Drive you need to have running again.

We test the critical areas of each drive regardless of the design or application.

Case Study: Preventing Unnecessary Repeat Repair Costs

Expert Fanuc A06B-6134-H203#A Drive RepairsHave you ever had to repair your electronic equipment twice?  Or more times even?  For the same, exact problem?  Maybe, for example, an expensive drive repair?  This unfortunate situation does happen with some regularity and it can usually be prevented by taking some simple, no cost/low cost steps.

Here’s a very recent case study in which this scenario was completely averted.  A Fanuc drive arrived on our loading dock needing repair.  Enclosed with the unit were notes about the errors it was showing.  Notes are great!

The repair was completed and shipped back like clockwork, but here’s the big difference.  The customer wanted to know some possible causes for this particular failure.  There are many of course, but here are a few we provided them to help isolate the problem:

Possible Drive Failure Causes

1. Open fuse.

2. Defective main power contactor.

3. Open or loose connections in wiring.

4. Defective step down transformer if one is used in this application.

A little time spent investigating the root cause of the failure before reinstalling a repaired unit can save you a big headache and a chunk of change.

Is this rocket science?  Heck no.  A big surprise?  Of course not.  But the prevention approach does bear repeating because it is too often overlooked.  Save yourself the headache and the extra money by checking out the integrity of the machine your damaged unit came out of before reinstalling the repaired unit.  Simple.  Worth it.  No extra money spent on repeat drive repairs this time!

Servo Drive Improvement and Repair Options

Expert Fuji Drive RepairsVariable frequency drives for motor driven systems is pretty much a no-brainer what with the energy savings and process improvements.  If you are looking for some beneficial reasons to invest in a VFD take a look at this post I wrote awhile back  If you want to know the story about this bad-a@# drive read on.

Like anything else in your plant, drives can break down like the pictured Fuji drive .  This drive comes out of a facility making turned parts and they are busy…well, they were busy.   This drive has had a number of failures and alarms over the past year and eventually overheated, stalled the machine and melted the drill in the work piece. And as a final insult, when in constant surface speed the drive alarms out under voltage when the spindle accelerates hard.

However tempting, this customer did not drop kick the defective unit to the moon and instead sent it half way around the world to our expert drive repair team.  After evaluating the unit, replacing numerous parts, cleaning and testing, this bad boy is nearly ready to be carefully packed and shipped back to work.

Plant & Facilities Managers Ace Problem Solvers – Hear What’s On Their Minds

Three cheers for the facilities, maintenance, and plant managers out there!  No, make that TEN cheers!   What a great bunch of nimble and creative people who increasingly have to achieve more with less…and for the most part, enjoy that challenge.
Besides just flat out asking our customers what’s up in their world, I also like to participate in various online forums and social media for facilities, maintenance, and plant managers.  What I hear is that you all really love solving plant problems and finding solutions to nagging plant issues that effect energy efficiency, sustainability, construction, plant equipment, security, and safety.
You love the daily variety of the work and the chance to make things run better.  Not that things are always perfect.  I also hear your frustrations such as “maintenance is the first department to get budget  and staffing cuts”,  “ too many regulatory and  changing requirements”,  “ tough to find electrical technicians with the right set of skills”, and “adhering to someone else’s timeline”.
Nevertheless, I am awed by the overwhelming positivity you guys continue to express and the ways you find to solve the problems at hand.  For example, one fellow was frustrated with the fact that management made decisions and budget cuts without really understanding what he was up against.
He didn’t yell or go home and beat the dog; instead he threw a party in the engine room and invited management.  They came and were fascinated, learned a thing or two and got to meet the people that actually make it all work.  The next time they rework the budget, they will do so with a greater understanding of the facilities’ needs.
Our goal is to help you achieve your goals when you need industrial electronic repair services.  Whether it’s servo motor repairs, or drive repairs, power supply repairs… whatever it is, let us know the situation…the more we know the more we can help.  If it’s a super rush, let us know and our technicians will do everything possible to meet your requirements.
As one forum writer noted, being a Plant/Facilities/Maintenance Manager is not for the faint of heart nor the slow of mind.  I think we can all agree on that.
