Positive travel limit switch detected

¿Qué significa F643 ?

The DIAX04 SSE-03VRS drive has detected that the physical positive travel limit switch has been activated. This indicates the machine axis has reached the physical end of its travel in the positive direction. The drive faults to prevent overtravel and potential mechanical damage, even if software limits might still allow further movement.

• Machine axis physically moved to the positive end of its travel, activating the limit switch.
• Incorrectly configured positive software travel limits, allowing motion too close to the physical limit switch.
• Faulty positive limit switch that is stuck in the active state or incorrectly wired to the DIAX04 SSE-03VRS drive.
• Overshoot due to aggressive deceleration ramps or high inertia, causing the axis to hit the limit switch.
• Mechanical adjustment of the limit switch is incorrect, placing it too early in the travel range.

1. 1

   Manually move the machine axis slightly back from the positive limit switch until it deactivates.

2. 2

   Inspect the physical positive travel limit switch for any damage, misalignment, or mechanical obstruction that would cause it to activate prematurely.

3. 3

   Verify the wiring of the positive limit switch to the DIAX04 SSE-03VRS drive for continuity, shorts, or incorrect connections.

4. 4

   Check the mechanical adjustment of the limit switch. Ensure it is positioned correctly relative to the desired travel range.

5. 5

   Review the positive software travel limit parameter (e.g., S-0-0049) in the DIAX04 SSE-03VRS drive to ensure it is set well within the physical limit to provide a buffer.
