Software Limit Switch CCW Exceeded

What does FF0204h mean?

This fault indicates that the specified position or the actual position of an axis has moved beyond the defined counter-clockwise (CCW) software limit switch. This condition prevents further movement in the CCW direction and halts the axis system to prevent overtravel.

• Axis position exceeded the defined counter-clockwise software limit switch.
• Encoder feedback indicates movement beyond the minimum allowed CCW position.
• Incorrectly set CCW software limit parameter.

Click steps to track your progress.

1. 1

   Review and adjust the counter-clockwise software limit parameter (e.g., P5-41) to a lower value.

2. 2

   Manually move the axis to a safe position within the limits.

3. 3

   Check the actual encoder position reading (e.g., P5-03) to confirm it is within the new limits.

4. 4

   Ensure the homing procedure correctly sets the initial reference position.
