Built-in brake chopper (R-, R+/UDC+, UDC-) in frames R0…R2 and (R-, R+) in frame
R3. Conducts the surplus energy from the intermediate DC circuit of the drive to
the brake resistor when necessary. The chopper operates when the DC link voltage
exceeds a certain maximum limit. The voltage rise is typically caused by decelera-
tion (braking) of a high inertia motor. The user obtains and installs the brake
resistor when needed.

Frames R0...R2
The layout of a frame R0 drive is presented below. The frame sizes R1…R2 is similar
to R0 but have a different structure.
