ENCERR_INVALID_CONTROLLERTYPE

Beckhoff · TwinCAT 2 NC

¿Qué significa 44A3 ?

This error signifies that an invalid controller type has been configured or detected for an encoder. The system expects a specific type of controller for the connected encoder but found a mismatch or an undefined type. This mismatch prevents the NC from applying the correct control algorithms and parameters, rendering the encoder unusable.

Causas comunes

  • The controller type parameter (e.g., P1-04, Controller Type) for the encoder is configured incorrectly (e.g., set to 1 when a 2 is expected).
  • Mismatch between the physically connected encoder type and the encoder controller type configured in the drive or system parameters.
  • Attempting to use an unsupported encoder controller type with the current drive firmware version.
  • Data corruption during parameter download, causing the encoder controller type parameter to be set to an invalid value.
  • Incorrect selection from a dropdown menu in the configuration software, leading to a mismatched controller type.

Pasos de reparación & Lista de verificación

Haga clic en los pasos para seguir su progreso.

  1. 1

    1. Access the encoder controller type parameter (e.g., P1-04) in the drive configuration and set it to match the actual encoder and controller specifications (e.g., 1 for incremental, 2 for absolute).

  2. 2

    2. Consult the encoder's datasheet and the drive's manual to confirm the correct numerical value for the encoder controller type.

  3. 3

    3. Check for any available firmware updates for the drive that might introduce support for the intended encoder controller type.

  4. 4

    4. Perform a parameter upload from the drive and then a download of the corrected parameter set to ensure data integrity.

  5. 5

    5. Visually inspect the encoder and verify its model number to definitively determine its actual type (e.g., incremental, absolute, resolver).
