Button disabled

What does 85 mean?

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.

• 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.

Click steps to track your progress.

1. 1

   Navigate to Parameter P0-10 (LCP Control Mode) and ensure it is set to 'Local' if local control is desired.

2. 2

   Check Parameter P0-40 (LCP Hand/Auto), P0-41 (LCP Start/Stop), and P0-42 (LCP Reset) to ensure desired buttons are enabled.

3. 3

   Verify that no external digital input (e.g., Terminal 18, 19) is configured to disable LCP functions via parameter group 5-** (Digital Inputs).

4. 4

   Unlock the LCP by checking Parameter P0-02 (LCP Lock Function) and entering the correct unlock code if it is enabled.

5. 5

   Test the physical responsiveness of the LCP button; if it's mechanically stuck, clean or replace the LCP.
