Control Panel Locked

What does 99 mean?

The control panel functions of the drive have been locked via parameter 018. This feature is typically engaged to prevent unauthorized access or accidental parameter changes during normal operation, enhancing safety and system integrity. While a security measure, it prevents local adjustments.

• Parameter P1-19 (Control Panel Lock) has been set to a value other than 0 (Unlocked), preventing local keypad operations.
• External digital input configured to lock the control panel (e.g., DI5 mapped to P1-19 via P5-01).
• Password protection (P1-10) is active, and an incorrect or no password was entered, locking certain functions.
