Should You Buy Indramat on eBay? 1

Posted on 16, May 2018

in Category Blog, Featured, Indramat Tips, Rexroth Service

You can buy Indramat drives, servos, and controls on eBay, no question about it. I checked just a minute ago and found more than four thousand choices for a simple search on “Indramat.” The question is not, “Can you buy Indramat on eBay?” The question is, “Should you buy Indramat on eBay?” At first glance it might seem like a good idea. There are plenty of items to choose from, and the prices are dramatically lower in some cases than what you would expect to pay for new or factory refurbished Indramat motion control. Who doesn’t like a bargain? Here [&hellip

Indramat Controls, Troubleshooting, and Batteries 0

Have you ever had one of those special cars? The door doesn’t open when it’s cold, and when it’s hot the trunk won’t stay up when you open it. You have to turn the key just the right way to make it start, and the window needs to be pulled up manually from the top when you roll it up, or else it starts going crooked and will never get a good seal at the top. It also stalls if you stop on a rainy day, so you just have to coast through stops in damp weather, and it needs [&hellip

The Need for Speed 0

Do you want to speed things up in your plant? Are you sure? Faster is usually possible, but will the equipment take the load? What will the next bottleneck be? We had a client who spent a ton of money to speed up the packing section of his plant to 2x the capacity. He could run his lines at 1600 widgets a minute. Pretty exciting. Unfortunately, the batching capacity of product at the front end of the plant turned out to be maxed out at 1.1x the previous rate. Our client would have had to build an entire new batch [&hellip

Get to Know the Rexroth Indramat DKS 0

Posted on 15, November 2017

in Category Blog, Indramat Tips

Indramat DKS Servo Drives are integrated drives, combining power and control in one unit. The official name is “Intelligent Digital Servo Drive.” The drive is connected to the servo motor with a power cable and a feedback cable. Software modules and auxiliary plug-in cards ensure that, if your Indramat DKS drive has to be replaced, you can transfer the software and configurations quickly to the new drive without excessive loss of time or information. They come in a couple of flavors: DKS 1.1 and DKS 1.2. There is no obvious difference between the two, if you just look at the [&hellip

Getting to Know Rexroth Indramat Error Messages 0

Rexroth acquired a company called Indramat in the 20th century. This company became the electric drive and control division of Rexroth. There are still legacy Rexroth Indramat machines in service today. Since they rarely have problems, you might see that Indramat name for the first time when something breaks down and you have to open the cabinet. “Indramat,” it says. And an error code. So how do you read and understand the error code/ Indramat error codes consist of a number and some text. For example, you might see F228 excessive output error The diagnostic number (here, F228) typically shows [&hellip

Why Do We Call It a Servomotor? 0

Posted on 27, October 2017

in Category Blog, Indramat History, Indramat Tips

You may call it a servo motor, servo-motor, servomotor, or just a servo. Indramat called their 20th century original an “AC Servo.” Why? While it has been suggested that the French cerveau (brain) might be the root for this term, it’s more likely to be the Latin servus, which gives us (and the French) words like “service” and “serve.” It appears that the term “servomotor” in English did come from the French servomoteur in the late 1800s, and it’s therefore conceivable that the French use of the word included a pun on cerveau, but it’s clear that the “servo” part is [&hellip

Want to Double Your Throughput? 0

Posted on 23, October 2017

in Category Blog, Indramat Tips

Improving throughput is almost always a goal in plants in every industry, since increased throughput leads to lower costs and increased profits — and who doesn’t like that? Often, managers assume that a significant increase in throughput is only possible with a significant upgrade in machinery — or maybe in staff. Calculating the ROI gets tricky, and thoughts of improvement get put aside for later. It doesn’t have to be that way. We worked with a company that had an automatic packaging system producing fewer than 600 pieces per minute. Just by upgrading the controls, we brought them to 1400 [&hellip

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
