Safety related end position exceeded

What does F7021 mean?

The motor's actual position has exceeded a safety-related end position limit. This is a critical safety function similar to F7011/F7012 but often refers to an absolute physical stop or a final safety limit, indicating that the axis has moved into an unsafe zone.

• Uncontrolled motion beyond the defined safety end position.
• Incorrectly configured safety-related end position parameter.
• Faulty position feedback (encoder) providing incorrect actual position values.
• Mechanical failure (e.g., brake failure, coupling slip) allowing overrun.

Click steps to track your progress.

1. 1

   Verify the configured safety-related end position parameter in the IndraDrive against the machine's safety documentation.

2. 2

   Check for any mechanical issues such as worn brakes, loose couplings, or physical obstructions.

3. 3

   Inspect the position encoder for proper operation, secure mounting, and reliable signal output.

4. 4

   Review the motion control program and command sequence for unintended movements near the end positions.

5. 5

   Perform a full homing or referencing procedure if the axis position reference is lost or incorrect.
