Negative travel range limit switch activated

What does E8044 mean?

The negative hardware travel limit switch has been activated, indicating that the axis has reached its maximum physical travel in the negative direction. This typically results in a controlled stop.

• Programmed motion or jog command caused the axis to activate the negative limit switch.
• Incorrectly set software limits, allowing motion to reach the hardware limit.
• Mechanical overtravel due to inertia or incorrect braking after the software limit.
• Faulty negative limit switch or its wiring.

Click steps to track your progress.

1. 1

   Manually jog the axis in the positive direction to clear the limit switch and return to a safe operating range.

2. 2

   Verify the negative software travel limit parameter in the drive controller and adjust it to be inside the hardware limit.

3. 3

   Inspect the negative limit switch for physical damage, proper mounting, and verify its wiring for continuity.

4. 4

   Check the motion program for any commands that might cause the axis to intentionally or unintentionally hit the limit switch.
