7 Things to Know When Choosing an Industrial AC Drive

June 10, 2015

Seven Things To Know When Choosing An AC DriveWhich industrial AC drive should I use? Picking the correct features of a Variable Frequency Drive for your particular application can leave you scratching your head. Here are 7 things to know and should consider when picking the right AC drive for your need.

1. Know the AC drive’s electrical current limit
Your industrial AC drive supplies current to your motor and shut it on and off. Every time your motor shuts off and on, current will spike in your AC drive. Knowing your AC drive’s electrical current limit will ensure that the motor doesn’t burn itself or the AC drive out. It can also let your AC drive shut the motor off in the event the motor begins to draw too much current.
2. Find the motor’s name plate information
The motor your AC drive operates will have a plate of information on it giving you the specs it needs an AC drive to have. Information like horsepower, torque, current draw and etc., are all displayed on the motor so it’s important to match the AC drive to the motor, not the overall system itself.
3. Know your motor’s duty cycle
The AC drive you choose will need to account for the duty cycle of its motor. If the motor is running nonstop or for extended periods of time, it will generate heat and begin to operate less efficiently or even burn up as a result. Picking the right AC drive with the right programming allows it to monitor the motor’s condition and mitigate the productive losses to a minimum.
4. Know what your industrial AC drive communicates with.
Your AC drive needs to chat with other buddies besides the motor. As part of a larger, complete system, your AC drive may need to communicate with a Data Collection System (DCS) or Controlling System. These systems can PC-Based or controlled automatically by a Programmable Logic Controller (PLC). Knowing your systems communication protocol allows you to choose an AC drive with the same or even multiple communication protocols.
5. Know your AC drive’s control method.
Your AC drive can be controlled using a variety of different methods. Depending on whether it will be a local, analog or digital control method, the AC drive will need to be set up differently. Each method requires different wiring and ports, so knowing this beforehand will make selecting an industrial AC drive easier.
6. Know the environmental conditions.
An AC drive will likely operate under less-than-perfect conditions. Take into account how dusty its operating environment will be. How hot will it get? Is there moisture? Industrial AC drives can come built with an Ingress Protection rating, which will give it varying degrees of resistance to adverse conditions. You could also choose a housing cabinet that will protect a standard AC drive.
7. Know your available power.
Knowing what kind of electrical supply you already have will let you select the right industrial AC drive. For example, if you’re using a 120 volt wall outlet, you can select an AC drive that’s capable of operating on that power supply. If it’s more, pick a higher volt AC drive. If it’s lower, pick a lower volt AC drive. — Troy Hardy, Field Application Engineer

Legendary…Even When You Don’t Want To Be. Customers Always Win.

January 16, 2014
Only the greatest ball park in excistence.

Only the greatest ball park in existence.

I love baseball.  I love baseball more than the normal baseball lover.  The MLB Network is on my television even in the off-season.  My wife has come to the point of watching baseball even when I am not around because she has become accustomed to it.  My first-born came into the world right as my beloved Red Sox won their 3rd championship in ten years and I could not be happier about it.  What does this have to do with being legendary though?

At my house, we always buy a ton of buffalo wings for the All-Star game and World Series and bask in the glory of this beautiful game while taking in way too much food.  For this past year’s MLB All-Star game, I was on-call for customer service after hours.  I was sitting on my couch with 50 of the most delicious looking wings in front of me. Right as the American League line-up was being announced, the phone rang.  A field service tech from the company had left an enclosure door open in the rain and the inverter drive was ruined.

I took off my baseball wearing shoes and slipped into my Legendary cape and tights and with a screaming baby in the backseat and my wings and baseball sadly calling my name, I saved the customer from being down any further.  My wings were still there when I came home and the customer was happy. LEGENDARY.

P.S. Go Red Sox.

When IDM was first developing AC drive technology for the oilfield, we received a large contract for an experimental rig on Pico street in Hollywood California.

The rig is surrounded by 20+ foot tall brown brick walls and from the street the Derrick appears to be a clock tower. Due to its location it has to be for all intents silent. The draw works is basically a roller coaster on Teflon slides powered by 6 parallel Siemens motors driven by Yaskawa modular drives. The mud pump is two long bi-directional pistons driven in a coordinated fashion so that there is always a consistent flow again driven by Yaskawa modular drives.
The startup took months and we stayed in Santa Monica. (Btw The Big Blue bus is a great way to get to the beach/pier.) Richard Lewis our lead engineer on the project got his “Hollywood” nickname on this project.

After working 12-hr days for months on the project the roughnecks and our crew became quit close knit (they would climb onto the draw works and ride it to the top of the derrick). The last day I was on site I was sitting on the steps of the SCR house looking down at the driller when he looked up at me and asked if I would like to come down and do a little rough necking to which I yelled back “I would love to but I’d hate to put 2 of y’all out of work” … I then had to dive into the SCR house to avoid the hail of wrenches, nuts, rocks, etc…it appears rig hands don’t like to be bested by a mere technician.

Yaskawa DriveWorks EZ Controls Antenna’s Azimuth Axis

August 19, 2013

Here’s a postcard I got from the always helpful Adam Ring, one of our key engineered solutions pros. Adam failed to mention the temperature was around 104 degrees this day in North Texas. That’s Adam in the blue shirt in the sun, and our skateboard pro customer Dave Johnson in the white T-shirt checking things out on the meter. And yes, those are Yaskawa drives in the control box.

Pepper,

Here are some pictures from the customer’s Signal Test Range.  I was helping tweek the Yaskawa DriveWorks EZ control algorithm that I developed to control this new antenna’s Azimuth axis.  By the end of the day, the system was purring like a kitten.  We implemented some very creative methods to very accurately control the position of this antenna and combat the effects of backlash in the gears as well as high winds. It’s a 9.4 meter Satellite Earth Station Antenna which means it’s more than 30 feet in diameter. — Adam Ring, Innovative-IDM

Yaskawa Application Overview: Lathe

Click here for the full “Application Overview: Lathe” from Yaskawa.

Yaskawa Lathe Applicaiton

A metal lathe usually spins the work piece along a horizontal axis. A mandrel or chuck is mounted to the headstock of the lathe. A follower block or tail block is mounted to the tailstock. A blank piece is clamped to the lathe and pressure is applied to the blank via a cutting tool. Material is cut away on each pass across the blank. After each pass, the lever arm is moved closer to the final position. Eventually, when the proper amount of material has been removed, the part is completed.

Yaskawa AC drives can be interlocked with the CNC control systems so the operation of the CNC controller and the AC drive are synchronized.

In addition, the Energy Saving Mode in Yaskawa AC drives automatically detect changes to the amount of torque required during shaping and finishing phases. This feedback enables the drive to quickly detect changes as the cutting tool becomes dull.

Automatic Energy Savings with VFDs Saves Motor Life, Too

September 18, 2012

In most pump applications, motors do not need to run at full throttle to get the job done. Yaskawa’s Michelle Bartlelson reminds us on the Linkedin Drives board that, on average, these motors can meet demand by running at just 70 percent of shaft speed. The additional system capabilities, she writes are usually reserved to accommodate future expansions or infrequent increased load demands. And that’s where a VFD can help. Various controllers can be used to run a motor at reduced speed.

A VFD can be used to operate a pump motor at any speed, and operating a pump motor below base speed to meet the requested demand can show significant energy savings. There is a whole article about it in Modern Pumping Today magazine.
