Keypad Battery Low Voltage
Yaskawa · V1000
¿Qué significa bAT ?
The keypad battery voltage has fallen below the acceptable threshold, indicating a low power state. If left unaddressed, this can lead to loss of real-time clock functionality or stored parameter values on the keypad. It is a precursor to complete battery failure.
Causas comunes
- The keypad's internal battery has reached its end of life and can no longer hold sufficient charge.
- Extended periods of the drive being powered off, causing the battery to drain without recharge (if applicable).
- A defect in the keypad's battery charging circuit, preventing proper recharging.
- Incorrect battery type installed (if user-replaceable), leading to rapid discharge or incompatibility.
