Incorrect direction of motion

What does F7031 mean?

The motor attempted to move in a direction opposite to the allowed or commanded direction during a safety-monitored operation. This fault indicates a serious discrepancy between the expected and actual motion, usually triggered by a safety function like Safe Direction.

• Incorrect phase sequence of motor wiring.
• Inverted encoder signals or incorrect encoder wiring.
• Incorrectly configured safety direction parameter.
• Control error or unintended command causing reverse motion.

Click steps to track your progress.

1. 1

   Verify the motor phase connections (U, V, W) to ensure correct rotation direction relative to commands.

2. 2

   Check the encoder wiring for correct polarity and signal integrity; ensure signals are not inverted.

3. 3

   Review the safety direction configuration parameters in the IndraDrive and ensure they match the application's requirements.

4. 4

   Test the motor's actual direction of rotation against a commanded positive and negative movement in a controlled environment.

5. 5

   If the problem persists, the drive's control of direction or its interpretation of encoder feedback might be faulty.
