When To Upgrade 2

Posted on 9, August 2017

in Category Blog, Indramat Tips, Rexroth Service

After having been in this business for longer than I care to think about, I find that upgrading is probably the most misunderstood and poorly approached action that people take with their machinery. People who will spend months analyzing the purchase of new equipment will launch into the upgrade of an existing piece of equipment at the drop of a hat. There are outside drivers of this as well. Sales people, by their nature, want to sell things. Misdiagnosed problems with equipment can make it seem as if an upgrade is the easiest way to get a problem off your [&hellip

Motion Control Systems: Repair or Replace? 0

Posted on 2, August 2017

in Category Blog, Indramat Tips

When your servo motor or servo drive quits working, you have some options. You can try to troubleshoot it and fix it on the machine, you can remove it and send it back to the factory for fixing, you can send it to a third party repair shop, or you can replace it. Which is the best choice? First, we have to recognize that some parts can’t be repaired in situ. Digital motors can’t be opened and worked on in the field as though they were in need of a new battery. (Sometimes things are in need of a new [&hellip

Bringing Rexroth Components Out of Storage 0

Posted on 13, July 2015

in Category Blog, Indramat Tips

You’ve had your Rexroth legacy drives in storage for 18 months or so, you reinstall them on the line, power them up, and for some reason they don’t work, even though they were working fine when you put them into storage. What’s up? First, check the cables. We can’t count the number of times we’ve come out on an emergency call and found a kink in the cable. Since this is one of the easiest things to check, it makes sense to look here first. Next, check the battery. Not all Rexroth legacy components use batteries, but some do. The [&hellip

F277- It’s Dead, Jim 0

Posted on 7, January 2015

in Category Blog, Indramat Tips

F277 is a relatively low information error, which is fine because there isn’t much you can do with it. The official description is “Current Measurement Trim Wrong”, which is pretty uninformative. The verbiage in the manual is not much more help. So what is that F277 error? The short answer is that F277 is caused by a hardware failure in the drive, despite the fact that the description talks about parameters. Those parameters are not values you can change.  And what exactly would you change them to, if you could change them? F277 used to be the hallmark of a [&hellip

Indramat Error Code F226 0

Posted on 13, October 2014

in Category Blog, Indramat Tips

Industrial motion control, including servo motors and drives, are set up to stop if continuing to work would be dangerous to the machinery or to the people operating it. Fortunately, Indramat drives don’t just stop and leave you wondering what’s going on. They communicate with you, sharing their inmost thoughts, or at least the reason they’re not working. Error codes are usually 4 digit alphanumeric codes beginning with E or F. Today, we’ll look at error code F226. F226 is the undervoltage error.  You can see it in the EcoDrive family or in the DIAX04 drive. The drive monitors the [&hellip

Testing Motion Control Performance 0

Posted on 27, August 2014

in Category Blog, Indramat Tips

We specialize in legacy Indramat motion control components. Chances are, if you use Indramat motion control, you’ve thought about testing them at some point. It might have been when you stumbled into a cabinet and opened it to find a servo older than yourself. Is this thing still performing as it should? you might have wondered. You can test them. Disturbance rejection and profile tracking are the most popular approaches to use when testing motion control for performance, since they cover the broadest range of applications. Disturbance rejection testing measures the motion controller’s ability to adapt to external disturbances. Initially, [&hellip

Cabinet Health for Your Indramat Drives 0

Posted on 23, July 2014

in Category Blog, Indramat Tips

We often get calls from engineers who have just opened a sealed cabinet for the very first time and found a mysterious object marked “Indramat.” Often the cabinet has been ignored for years, even decades, and it was only found by following the cable to it from a piece of equipment that has stopped doing its job. With smoke and sparks settling around him and managers gabbling in his ears, our hero Googles “Indramat,” finds us, and starts on the road back to wellness (for the factory). We’re happy to help. But sometimes a periodic check of the cabinet could [&hellip

No Cabinet Motion Control? 0

Posted on 16, May 2014

in Category Blog, Indramat Tips

One of the trends in industrial motion control right now is a move away from the need for a cabinet. Those air conditioned boxes your servos live in take up space, and space can be costly. Reducing the footprint of your motion control system can be desirable. Doing away with air conditioning can be a cost-cutting measure, too. We often see cabinets propped open with a fan trying to take the place of air conditioning, so we know that this is an appealing idea. The catch is, you can’t just decide to quit using a cabinet. This isn’t like a [&hellip

Incorrect Personality Module? 0

Posted on 5, May 2014

in Category Blog, Indramat Tips

One of the special features of Indramat servomotors is the “Personality Module,” known in Europe as a programming module. The Personality Module is programmed with the settings that ensure compatibility between the servo amplifier and the motor. These Personality Modules make configuration easy. When you replace an Indramat drive, you can just pull the Personality Module out of the old drive and pop it into the new one. It’s ready to go. What happens if you have the wrong Personality Module? Here’s a sampling of possible results: irregular feed overshoot during positioning drive doesn’t follow commands In other words, plenty [&hellip

What Indramat Control Do You Have? 0

Posted on 25, April 2014

in Category Blog, Indramat Tips

Indramat made three basic types of control: CLM CLC PPC Each of these controls comes in a variety of flavors. When you need a replacement or repair, you’ll need to know the details of your control. How can you tell which one you’ve got? Here are some questions that will help you identify the control you’re using. Does it have removable firmware? The CLM 1.2 does not. This is the most basic of the controls. You’ll find removable firmware just below the keypad on the other CLM models. What color is it? CLM controls often say “CLM” directly on the [&hellip
