3AXD50000011888
2.5.1 Main Circuit
The main circuit of the drive is shown below.
Figure 2-3
Table 2-2
1
Rectifier. Converts alternating current and voltage to direct current and voltage.
2
DC link. DC circuit between rectifier and inverter.
3
Inverter. Converts direct current and voltage to alternating current and voltage.
4
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. User obtains and installs
the brake resistor when needed.
