Resistor braking
Contents of this chapter
The chapter describes how to select the brake resistor and cables, protect the
system, connect the brake resistor and enable resistor braking.
Operation principle and hardware description
The brake chopper handles the energy generated by a decelerating motor. The
chopper connects the brake resistor to the intermediate DC circuit whenever the
voltage in the circuit exceeds the limit defined by the control program. Energy
consumption by the resistor losses lowers the voltage until the resistor can be
disconnected.
For frame R0…R3 internal brake choppers and resistors, see below. For R4…R9
external brake choppers and resistors, see on page
