Power ready configuration incorrect (_ecPOWER_READY_CONFIG_WRONG)

ABB · ACS850 Standard Program Firmware

¿Qué significa 234 ?

This error indicates an incorrect configuration when assigning POWERREADYINPUT or POWERREADYOUTPUT to an I/O. This can be caused by incompatible INPUTMODE/INPUTACTIVELEVEL/OUTPUTACTIVELEVEL settings, or by attempting to reconfigure an I/O that is already designated as POWERREADY. This prevents the drive from correctly signalling or detecting its power-ready status, potentially impacting system safety or startup sequences.

Causas comunes

  • Configuration of a digital input as POWERREADYINPUT with an incompatible INPUTMODE (e.g., using an Analog Input mode).
  • Mismatch between the INPUTACTIVELEVEL parameter (e.g., P8-01 (Digital Input 1 Active Level)) and the actual wiring or PLC logic for the POWERREADYINPUT signal.
  • Attempting to assign POWERREADYOUTPUT to an I/O terminal that is already configured for a conflicting critical function.
  • Incorrect OUTPUTACTIVELEVEL setting (e.g., P8-10 (Digital Output 1 Active Level)) for the POWERREADYOUTPUT, leading to an inverted or incorrect signal state.

  1. 1

    Access the drive's configuration software and verify the I/O assignment for POWERREADYINPUT, ensuring it's mapped to a digital input terminal (e.g., DI1, DI2).

  2. 2

    Check the INPUTMODE parameter (e.g., P8-01 (Digital Input 1 Mode)) for the assigned POWERREADYINPUT and set it to the appropriate digital input type (e.g., "Normal Digital Input").

  3. 3

    Confirm the INPUTACTIVELEVEL parameter (e.g., P8-02 (Digital Input 1 Active Level)) matches the expected voltage level (e.g., "High Active" for 24VDC, "Low Active" for 0VDC).

  4. 4

    For POWERREADYOUTPUT, ensure the assigned digital output terminal (e.g., DO1, DO2) is not being used by another critical safety or control function.

  5. 5

    Adjust the OUTPUTACTIVELEVEL parameter (e.g., P8-11 (Digital Output 1 Active Level)) for the POWERREADYOUTPUT to ensure the correct active state (e.g., "High Active" for 24VDC, "Low Active" for 0VDC).
