What causes Indramat error F811?

An F811 error diagnostic message indicates commutation offset could not be determined. This means that your system’s automatic commutation adjustment has failed to determine the commutation offset.

There are several things that might cause an Indramat F811 error:

  1. Something is preventing motor movement.
  2. Incorrect direction encoder movement.
  3. Incorrect motor polarity.
  4. Movement prevented by a blocked axis.
  5. Movement prevented by brake.
  6. The axis is in in endstop position.

When it comes to troubleshooting Indramat errors, always start with the first possible cause in your Indramat troubleshooting guide and work your way down the list. Your manual lists the causes in order of most likely to least likely. For an F811 error code, the most likely cause is that something is blocking motor movement. An axis stuck in endstop position is the least likely cause.

Try these remedial actions for an F811 error:

  1. Look for a blockage preventing mechanical movement.
  2. Check the encoder, and invert the direction of movement if necessary.
  3. Check motor connection to the controller.
  4. Eliminate any mechanical blocking that prevents movement of the axis.
  5. Test the brake and control signals to make sure that the brake functions properly.
  6. Verify that the axis does not remain in endstop position

While you can work your way through the list and cross the possible causes off as you go, the fastest way to eliminate Indramat faults or errors is by contacting Indramat professionals.
