BP1

The DC bus is overloaded. In this case, unlike diagnostic message 8107 Overcurrent, switch off does not occur as soon as the current threshold has been exceeded. The thermal overload of the device is observed for a specific time.

Cause

Solution

Too many loads are connected to the DC bus.

  • It may be that the existing device constellation is sufficient by adapting the application (for example, less acceleration).

  • Use another power supply and distribute supply of loads.
