1
Rectifier. Converts alternating current and voltage to direct current and voltage.
2
DC link. DC circuit between rectifier and inverter. DC choke is included in frames R6 to R9. An AC
input choke is included in frames R10 and R11.
3
Inverter. Converts direct current and voltage to alternating current and voltage.
4
Brake chopper (D150). 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 deceleration (braking) of a high inertia
motor. User obtains and installs the brake resistor when needed.

External brake resistor
