Error "positive position limit".

What does 155 mean?

The positive position limit (C1223) was exceeded, potentially due to incorrect position targets or issues with the 'set function position value'. This can cause the drive to overtravel its intended positive extreme.

• The commanded position target from the master controller or internal program exceeds the configured positive position limit (Parameter C1223).
• The 'set function position value' command has been applied incorrectly, causing an offset that pushes the commanded position beyond the positive limit.
• Inaccurate or corrupted homing data leading to an incorrect absolute position reference.
• Mechanical slippage or unintended movement causing the actual position to exceed the programmed limit.
• Programming error in the motion profile or PLC sequence, generating an invalid positive target position.

Click steps to track your progress.

1. 1

   1. Verify the positive position limit value (Parameter C1223) in the drive's configuration and compare it to the actual mechanical travel range of the system.

2. 2

   2. Review the motion program for any commands that set or offset the current position (e.g., 'set function position value') and ensure they are correct.

3. 3

   3. Re-execute the homing procedure to establish a precise and repeatable absolute reference point for the drive.

4. 4

   4. Monitor the actual position (P5-04) and commanded position (P5-05) in real-time as the drive approaches the positive limit.

5. 5

   5. Temporarily adjust the positive position limit (C1223) to a larger value, then manually jog the system to the desired positive mechanical stop and set C1223 just below it.
