When you see E2077 sent as an error message by your Rexroth drive, you’re looking at a communication failure. Basically, your drive can’t read the encoder signal. There are a number of possible reasons for this. Check the simplest possibilities first. Is the motor encoder cable correctly connected to the same drive as the power… Read more »
Rexroth error code F2187 is a common error that occurs when there is a loss of encoder 1 reference in a motor. This error message indicates that the motor encoder needs to be referenced using the internal drive command Set Absolute Reference. This process can be done either through the commissioning software or an external… Read more »
F8000 is the Rexroth IndraDrive code for fatal hardware errors. Fatal errors are the ones that make your machinery take things into its own hands by shutting down. You won’t often see “F8000” on your drive controller display. The message will be quickly followed by the best possible deceleration and a shutdown, plus a more… Read more »
Legacy Indramat motion control, as well as current Bosch Rexroth Indradrive electric motion control, will communicate with you using error codes that let you know what’s causing the problems you experience. Starting with the Diax 04 drives, the power supplies were able to generate many more errors than before and had a two digit display… Read more »
When your Rexroth Indradrive component throws an Error Code E8028, it is an indication that the motor has exceeded its maximum rated current. The output stage of the power section will be locked until the controller output returns to the allowed range of values. This can be caused by an overload, an electrical short-circuit, or… Read more »
Rexroth error messages are not random strings of letters and numbers. They come in various classes. This is the current run-down: F2xxx Error messages beginning with F2xx are non-fatal error messages. That means your machinery won’t automatically shut down. If you ignore these warnings, though, they’ll escalate. F3xxx F3xxx shows non-fatal safety technology errors. These… Read more »
Turn it off and turn it on again is a classic line, really a joke, but…sometimes it works. Rexroth error code E0220 can be one of those times. Rexroth error codes usually start with an E or an F, followed by digits that provide more detail on the problem. “E-0220” means that an unauthorized interrupt… Read more »
When our Eco Drive drive controllers are trying to communicate with us, we usually think in terms of fault codes or error codes. But it’s actually more complicated than that. For the ECODRIVE Drive Controller DKC02.1, for example, there are quite a few different diagnostic messages: Error diagnostic messages Warning diagnostic messages Command diagnostic messages… Read more »
F234 is the code for Emergency Stop Activated. This is obviously an important safety action, stopping machine movement which could damage your system or products, or which could create danger for your team. Knowing that this is a good thing doesn’t mean that you’re going to be happy to see Error Code F234. This code… Read more »
Not a week goes by without multiple calls from clients asking about F228 faults on their Rexroth Servo Drives. The manual has a very dense explanation for a very simple error, which often times leads clients down the wrong path. F228 means that the motor can’t keep up with where it is supposed to be….
