Negative position limit exceeded

What does E8030 mean?

The actual or commanded position has exceeded the configured negative software travel limit. This can lead to the machine reaching its mechanical hard stop or unexpected motion.

• Programmed motion or jog command attempts to move beyond the negative software travel limit.
• Incorrectly set negative software limit parameter.
• Loss of position feedback or incorrect encoder scaling, leading to misinterpretation of actual position.
• Mechanical overtravel due to inertia or incorrect braking.

Click steps to track your progress.

1. 1

   Verify the negative software travel limit parameter in the drive controller and ensure it is set correctly and safely for the application.

2. 2

   Check the commanded position values in the motion program to ensure they do not exceed the negative travel limit.

3. 3

   Inspect the position feedback system for encoder accuracy and scaling parameters.

4. 4

   Manually jog the axis to a safe position within the valid travel range.
