Positive travel range limit switch activated

What does E8043 mean?

The IndraDrive MPx02 has detected that the physical positive travel range limit switch (hardware limit switch) has been activated. This is a critical warning indicating that the axis has reached or exceeded its absolute positive mechanical limit, preventing further movement in that direction to protect the machine.

• Axis has physically traveled beyond its intended positive working range, activating the limit switch.
• Incorrect homing procedure or offset causing the axis to reference too close to the limit switch.
• Faulty limit switch or wiring, leading to false activation.
• Aggressive motion profile or uncontrolled movement causing mechanical overtravel.
• Accumulated position error over time, causing the axis to drift into the limit.

Click steps to track your progress.

1. 1

   Manually jog the axis in the negative direction, away from the limit switch, until it deactivates.

2. 2

   Inspect the positive travel range limit switch for physical damage, misalignment, or contamination that might cause false activation.

3. 3

   Verify the wiring of the limit switch to the IndraDrive MPx02's digital input, ensuring it is correctly connected and functioning.

4. 4

   Review the homing procedure and position reference settings to ensure the axis operates well within its physical travel limits.

5. 5

   Adjust motion parameters (e.g., deceleration, commanded position limits) to prevent the axis from approaching the physical limit switch during normal operation.
