How to Resolve the Battery Fault Displayed in XX_nr Software When the A6 Drive Starts Up?

When the A6 drive starts up, the XX_nr software may display a battery fault. This indication actually means that the encoder cable does not include a battery box—in other words, the dedicated cable for absolute encoder use was not purchased. Therefore, the absolute positioning function cannot be used.

As shown in the image below, we have added a NOTE and a hyperlink on the A6 product page. Alternatively, you can directly click those links to purchase the required cable.
