Parameter set mode is absolute instead of relative.

¿Qué significa 157 ?

An absolute parameter set (C1311) was performed or is active during relative positioning (position mode C1210). This mismatch in positioning modes prevents correct operation.

• The positioning mode parameter (e.g., C1210) is configured for relative positioning, but a motion command or parameter set (e.g., C1311) expecting an absolute position reference was issued.
• A program sequence in the master controller or internal drive logic incorrectly switches between absolute and relative motion commands without updating the drive's active mode.
• Incorrect parameter value downloaded for the positioning mode (C1210) not matching the application's intended operation.
• Communication error or corrupted data causing the drive to misinterpret the intended motion mode from the master controller.

1. 1

   1. Verify the current positioning mode (Parameter C1210) and ensure it matches the application's requirements (0 = relative, 1 = absolute).

2. 2

   2. Review the motion control program (PLC or master controller) for any instances where an absolute parameter set (e.g., C1311) is called while the drive is configured for relative mode.

3. 3

   3. Adjust the positioning mode parameter (C1210) to match the type of positioning commands being sent, or modify the motion program accordingly.

4. 4

   4. Perform a drive parameter backup and restore, or re-download the correct parameter set to ensure C1210 is accurately applied.

5. 5

   5. Monitor the drive's status words (e.g., P5-06 for mode bits) to confirm the drive's active positioning mode prior to the fault.
