The item Servo Positioning Controller C 3-Series has an internal brake chopper and braking resistor. For more braking power,
an external braking resistor can be connected to the [X9] pin-and-socket connector.

Specification
6 BR-EXT < 800 VDC Connection of the external braking resistor
7 BR-CH < 800 VDC Brake chopper connection for the internal braking resistor against
BR-INT and for the external braking resistor against BR-EXT
8 BR-INT < 800 VDC Connection of the internal braking resistor
(bridge to BR-CH when using the internal resistor)
If no external braking resistor is used, a bridge must be connected between PIN 7 and PIN 8 so that the
precharging of the DC bus circuit at mains power "ON" and the rapid discharge of the DC bus circuit are
operational!
