Braking resistor
The braking resistor is designed for the SINAMICS G120 inverters with an internal brake
chopper and enables loads with a large moment of inertia to be braked quickly. During
braking of the motor and the load, excess energy is fed back to the inverter. This causes the
voltage to rise in the DC link. The inverter transfers the excess energy to the externally
mounted braking resistor. The option is only available for the Frame Size B inverter.
Ordering information is given in the following table:
