Both travel range limit switches activated

What does F6042 mean?

Both the positive and negative hardware travel limit switches have been simultaneously activated. This is an illogical state, as the axis cannot physically be at both ends of its travel range at the same time, indicating a wiring error or sensor malfunction.

• Incorrect wiring of limit switches (e.g., common wire shorted, signals crossed).
• Faulty limit switches that are stuck in the activated position.
• Damage to the drive's input circuitry for limit switches.
• Incorrect configuration of limit switch input types (NO/NC).

Click steps to track your progress.

1. 1

   Disconnect power and verify the wiring of both positive and negative limit switches to the IndraDrive inputs for correctness.

2. 2

   Manually test the functionality of each limit switch to ensure they are not stuck and provide proper signal changes.

3. 3

   Check the drive's input status for the limit switches to identify which one might be incorrectly signaling.

4. 4

   Review the drive parameters related to limit switch configuration (e.g., S-0-0XXX Limit Switch Polarity).

5. 5

   If individual switches test correctly, inspect the drive's digital input circuitry for damage.
