Negative travel limit exceeded

What does F630 mean?

The DIAX04 SSE-03VRS drive has detected that the machine axis has moved beyond its configured negative software travel limit. This is a safety and machine protection fault, indicating that the axis is outside its allowed operating range, potentially risking mechanical damage or collision. The drive attempts to stop motion safely.

• Incorrectly configured negative software travel limit (e.g., S-0-0050) in the DIAX04 SSE-03VRS drive.
• Commanded position exceeded the negative software limit due to an error in the motion profile or control program.
• Faulty position feedback (encoder) providing incorrect position data, making the drive miscalculate its actual position.
• Mechanical system failure or excessive inertia causing overshoot beyond the commanded limit.
• Ignoring or overriding limit switch signals incorrectly.

Click steps to track your progress.

1. 1

   Manually move the machine axis back into the allowed travel range, ensuring no mechanical obstructions.

2. 2

   Verify and adjust the negative software travel limit parameter (e.g., S-0-0050) in the DIAX04 SSE-03VRS drive to match the actual mechanical limits.

3. 3

   Review the motion program or commands to ensure no position setpoints exceed the defined limits.

4. 4

   Inspect the motor encoder and its wiring for proper function and accurate position feedback.

5. 5

   Check the physical negative limit switch for functionality and correct activation, ensuring it is not bypassed or faulty.
