Error "actual reference dimension offset".

What does 158 mean?

The actual reference dimension offset (C1226) is outside the defined position limits. This indicates an error with the program function 'set position value' or incorrect limit settings.

• The 'set position value' function was used to define an offset that results in the actual reference position falling outside the configured software position limits (C1223, C1224).
• Accumulated error or drift in the homing process, combined with an offset, pushes the effective reference beyond the defined bounds.
• Incorrectly configured software limits (C1223, C1224) that are too restrictive for the intended operating range after an offset is applied.
• Corruption of the stored reference dimension offset parameter (C1226) due to electrical noise or memory error.

Click steps to track your progress.

1. 1

   1. Review the programming logic for the 'set position value' function and verify the offset applied does not push the resulting position outside C1223 and C1224.

2. 2

   2. Adjust the positive position limit (C1223) and negative position limit (C1224) to encompass the full intended travel range plus any potential offsets.

3. 3

   3. Re-perform the homing sequence and then carefully re-apply the 'set position value' function, monitoring the actual position (P5-04).

4. 4

   4. Examine the value of the actual reference dimension offset (Parameter C1226) for any unexpected values that might indicate corruption.

5. 5

   5. Log motion commands and drive position data (P5-04, P5-05) to pinpoint the exact sequence of events leading to the limit violation.
