247

Event not supported (_ecEVENT_NOT_SUPPORTED)

ABB · ACS850 Standard Program Firmware

What does 247 mean?

This error occurs when the Mint program attempts to use an event that is not supported by the drive's firmware or hardware. This prevents the intended event-driven logic from executing, potentially causing program failures or unexpected machine behavior.

Common Causes

  • Using an event type or specific event number (e.g., EVENT #10, which might be reserved for a future feature) that is not implemented in the current drive firmware.
  • Attempting to trigger an event that requires specific hardware (e.g., a secondary encoder input) not present on the installed drive model.
  • The Mint program was developed for a different drive series or firmware version that supported the specific event, but the current drive does not.
  • A custom or user-defined event is referenced, but the necessary supporting libraries or configurations are missing.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Consult the drive's Mint programming manual for the installed firmware version to verify the list of supported events and their corresponding numbers.

  2. 2

    If the event is linked to specific hardware, confirm that the required hardware (e.g., an encoder option card) is physically installed and correctly configured (e.g., P6-01 (Encoder Type)).

  3. 3

    Modify the Mint program to use an alternative, supported event type that achieves similar functionality.

  4. 4

    Update the drive's firmware to a version that officially supports the desired event, if available and compatible with the application.

  5. 5

    Simplify the event logic in the Mint program, breaking down complex event conditions into sequences of simpler, supported events or status checks.
