3.14 Braking resistor (X12/RB)
In regenerative operation, e.g. when braking the motor, power is routed into the DC
link of the multi-axis system and fed back via the Power Supply Unit to the mains.
If feedback to the mains is not possible (such as in the event of a power failure), the
internal braking transistor is activated and the regenerated power is converted into heat
by way of a braking resistor.
3.14.1 Connection of the external braking resistor
DANGER!
Terminal RB+ is permanently switched to DC link potential (>300 V DC).
The connection is not protected inside the device. Never wire or disconnect
electrical connections while they are live. Always disconnect the power
before working on the device. Dangerously high voltages ≥50 V (capacitor
charge) may still be present 10 minutes after the power is cut to the size 5 and
size 6A. The discharge time depends on the number of drives connected to
the multi-axis system. So check that no voltage is connected!
ATTENTION!
The external braking resistor must be monitored by the control. The
temperature of the braking resistor is monitored by a temperature watchdog
(Klixon). In the event of overheating the Power Supply Unit must be
disconnected from the mains supply.

3.13 Option 1
Depending on the Power Supply Unit variant, option 1 is factory-configured with various
options. Field bus options such as EtherCAT or SERCOS are available.
You will find all available options in the Programmable Multi-Axis Servo Drive System
(MSD) Ordering Catalog. The user manuals for the respective options provide detailed
information on commissioning.
