Positive travel range limit switch activated
Indramat · Indradrive
What does F6043 mean?
The hardware limit switch for the positive travel range has been activated, indicating that the axis has reached or exceeded its positive mechanical limit. This causes the drive to stop further movement in the positive direction to prevent damage.
Common Causes
- Mechanical overrun of the axis beyond the positive limit switch.
- Limit switch stuck in the activated position.
- Incorrect wiring of the limit switch or faulty input.
- Control program error commanding movement into the positive limit.
