What Is the Indramat E831 Error Code?

The Indramat E831 error code is one of several “E” class errors associated with Indramat’s DKC drive controllers. It specifically appears when the drive is set to IN REFERENCE and the position limit monitor is turned ON. As defined in the drive’s manual, this fault is described as:

“Position limit reached during jog.”

This means the drive has attempted to move beyond its programmed position limit during a jogging operation. While this error doesn't trigger an immediate drive shutdown, it serves as a critical warning that should be addressed right away to avoid long-term performance or safety issues.

What Triggers the E831 Error?

The E831 error is most commonly caused by issues that interrupt proper motor control. These may include:

• Loose or faulty cables

• Incorrect or corrupted configuration settings

• Faulty or improperly connected hardware connectors

Once communication between the control unit and the drive is disrupted, the system may inaccurately interpret positional data—causing the drive to hit a programmed limit and halt motion.

When Does It Happen?

This error often occurs during jogging, a control mode where the motor moves in small increments rather than continuous motion. If the drive attempts to exceed its allowable positional boundaries during this movement, it will trigger the E831 error.

How to Clear the E831 Error Code

Here are the recommended steps to resolve this error:

1. Return Motor to Permitted Travel Area

Use the jog function to manually move the motor back within the allowable position range.

2. Disable Position Limit Monitor (if appropriate)

If jogging is necessary beyond current limits and it’s safe to do so, consider temporarily disabling the position limit monitor in the configuration.

3. Inspect Physical Components

• Check all cables and connectors for damage, wear, or disconnection.

• Replace or secure any loose or faulty components.

4. Verify Configuration Settings

• Ensure the control unit and drive have matching communication parameters:

  • Baud rates

  • Data formats

  • Addresses

  • Protocols

5. Power Cycle the System

• Turn off the entire system.

• Wait briefly, then power it back on.

• Follow the manufacturer’s cold startup sequence detailed in the user manual.

FAQs

What is jogging in a motor?

Jogging, also known as inching, refers to short, controlled bursts of motor movement—commonly used to precisely position equipment. Jogging typically occurs at full torque for fine control but can easily lead to overshooting limits if not monitored.

Can I clear the E831 code without assistance?

Yes, if the cause is simple, such as a loose cable or misconfigured setting. However, if the error persists or is recurrent, it's best to seek professional support.
