1. AC supply. 1-phase 200...240 V or 3-phase 200...240 V phase-to-phase (±10%).
2. Rectifier. Converts alternating current and voltage to direct current and voltage.
3. DC link. DC circuit between rectifier and inverter.
4. Inverter. Converts direct current and voltage to alternating current and voltage.
5. Brake chopper. 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. The user must obtain and
install a brake resistor when needed.
