The item servo positioning controller C 1-Series has an internal brake chopper with brake resistor. For more brake power it is
possible to connect an external brake resistor to the connector [X9].
If no external brake resistor is used, a bridge must be connected between PIN 5 and PIN 6 so that the DC bus
precharge, when the mains power supply is “ON”, and the DC bus rapid discharge can function properly!
