Buffer Battery Undervoltage (U<22V)

What does Buffer battery voltage low mean?

The buffer battery voltage has dropped below 22V, indicating an undervoltage condition. This requires attention to maintain system integrity and prevent data loss.

• Buffer battery voltage dropped below P0-50 threshold (e.g., <22V).
• External power supply failure affecting buffer battery charging.
• Internal battery protection mechanism triggered due to low voltage.

1. 1

   Charge the battery.

2. 2

   Manually save the mastering data via KUKA HMI (`Setup > Master > Save current data`) before any battery exchange or power cycle.
