They’re Not All Error Messages

Your Rexroth electric motion control devices don’t just communicate error messages. In fact, Rexroth diagnostic messages usually indicate that everything is hunky dory. You only see Rexroth error messages if there is a problem with your system.

Here are the kinds of messages you might receive:

  • Error diagnostic messages
  • Warning diagnostic messages
  • Command diagnostic messages
  • Drive Mode diagnostic messages
  • Operation status

Diagnostic messages starting with E and F are error and warning messages. But other letters signal other types of diagnostic messages. For example, you might have an EcoDrive or DKS Drive Controller.

One day you see a cryptic D306 message.

A D306 message tells you that the power is off. That might sound like an error to you, but for Rexroth it isn’t even a warning. It’s just a useful piece of information. You can check the connections, turn the power, on and start over.

D310 is a request for the master password. Input the master password and you’re in business.

This type of message is easier to resolve than warnings and error messages. But it’s only easy if you know how.

Rexroth manuals

There are two ways to get that knowledge. First, you can request a manual for your machine. Click through to our manual request form, let us know which manual you need, and we will be happy to email you the correct manual.

Rexroth troubleshooting manuals are intended for experienced personnel. They don’t start at the beginning and they don’t take it slowly. They jump right into dense, technical information; your manual lets you know that your drive is in the torque control operating mode, and expects you to know what to do next.
