One of the best resources for Rexroth servo motors and servo drives is the manual itself—after all, the point of a manual is to give you all the information you need to operate and troubleshoot your Rexroth equipment. Manuals are the first place you should look when you have an Indramat or Rexroth drive and control issue.
If you don’t know where your manuals are for your Indramat or Rexroth equipment, you can request a new manual and we’ll send one your way. Bear in mind, Project Planning Manuals include safety information and installation instructions, not troubleshooting advice. You’ll need the Troubleshooting Guide for that.
Error codes
One of the most important things you’ll find in your Rexroth Indramat manual is a collection of error codes. Error codes are clues to what is wrong with your Indramat or Rexroth component.
These are the codes that show up when there’s a problem. Each entry in the manual gives the most likely problems, in order of likelihood. If you see the F218 error, for example, the most likely problem is that the ambient temperature is too high. Cool your space down and see if that helps.
If not, check for the next possible cause. For F218, it’s that the amplifier’s heatsink is dirty. Clean it and see if that solves the problem.
The third possibility is that something about the control cabinet assembly is preventing proper airflow. Examine your assembly and see if that helps.
- Finally, you may have a defective blower. To solve that problem, you can call us and get factory repair or an emergency replacement.

After troubleshooting
After you’ve given it the old college try, the next thing to do is call a professional. While the manuals for Indramat servos do have a lot of information in them, they don’t contain it all. Manuals don’t know the ins and outs of how the machinery actually fails—just standard procedures developed when the manual was first written years and years ago. Since then, servos are being used in new ways that can have very different effects that the original manual authors might not have foreseen.
That’s where manuals just aren’t useful. We still urge you to request a manual because it’s a good start. But be sure to keep our number written in the front of your manual, just in case. Here’s the number to call if you need expert assistance: (479) 422-0390.
