Positive travel range limit switch activated

Was bedeutet E8043 ?

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.

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.
