Button disabled
Danfoss · VLT Micro Drive FC 51
Was bedeutet 85 ?
A button on the Local Control Panel (LCP) has been disabled, likely through a configuration in parameter group 0-4* LCP functions. This is a safety or operational feature to prevent unintended or unauthorized operation via specific LCP buttons.
Häufige Ursachen
- Parameter P0-40 (LCP Hand/Auto) configured to disable specific buttons for operational safety or control strategy.
- Parameter P0-41 (LCP Start/Stop) or P0-42 (LCP Reset) explicitly set to 'Disabled' or controlled by an external source (e.g., digital input).
- LCP control mode (P0-10) set to 'Remote' (e.g., Fieldbus, Digital Inputs), which overrides local LCP button functionality.
- A faulty LCP button itself (stuck or non-responsive) could be misidentified as disabled by the drive's internal logic.
- Control panel lock feature (P0-02) enabled, preventing changes via LCP buttons without an unlock code.
