3 Product Overview
3.1 What this chapter contains
The chapter briefly describes the operation principle, product characteristics, layout, name plate and type
designation information.
3.2 Basic principles
CV50 inverters are wall and flange mountable devices for controlling asynchronous AC inductance motors.
The diagram below shows the main circuit diagram of the inverter. The rectifier converts three-phase AC
voltage to DC voltage. The capacitor bank of the intermediate circuit stabilizes the DC voltage. The converter
transforms the DC voltage back to AC voltage for the AC motor. The brake pipe connects the external braking
resistor to the intermediate DC circuit to consume the feedback energy when the voltage in the circuit exceeds
its maximum limit.

≤
30kW)
Diagram 3-2 The main circuit diagram
(
≥
37kW)
Note:
1.
The inverter above
37kW
(including
37kW
)
supports external DC reactor.
Before connecting, it is necessary
to remove the copper row between
P1
and

)
.
2.
The inverters (
≤
30kW) have standard embedded braking units and the braking resistor is optional.
3
.
The inverters (
≥
37kW) can be installed with optional braking units and the braking unit and resistor are
optional.
