4.15 Braking resistor (X12/RB)
In regenerative operation, e.g. when braking the motors, energy is fed to the DC link in
the multi-axis system and fed back to the mains via the supply unit. If it is not possible
to feed back the electrical power to the mains (e.g. mains failure), the internal braking
transistor is switched on and the regenerated power is converted into heat via a braking
resistor.
4.15.1 Connection of the external braking resistor
DANGeR!
Risk of injury due to electrical power!
•
Carelessness will result in serious injuries or death.
Terminal RB+ is permanently connected to DC link potential (>300 V DC). The connection is
not protected internally in the device.
Never make or disconnect electrical connections while they are electrically live! Before making
any change
the device is to be disconnected from the mains. Even 30 minutes after switching off the
mains supply dangerously high voltages of ≥50 V may still be present (capacitor charge). The
discharging time depends on the number of controllers connected to the multi-axis system. So
check that electrical power is not present! See chap. 4.1
NOTe:
The external braking resistor must be monitored by the controller. The
temperature of the braking resistor is monitored by a temperature
sensor (Klixon). In the event of overtemperature, the supply unit must be
disconnected from the mains. All drive controllers in the system must also be
deactivated.
WARNING!
Risk of injury due to hot surfaces on the braking resistor!
•
Carelessness may result in serious burns.
The braking resistor may become hot during operation!
For this reason maintain an adequate clearance to neighbouring assemblies or install the
braking resistor outside the switch cabinet.
