Rectifier. Converts alternating current and voltage to direct current and voltage.
1
DC link. DC circuit between rectifier and inverter.
2
Inverter. Converts direct current and voltage to alternating current and voltage.
3
Brake chopper. Conducts energy from the intermediate DC circuit of the drive to the brake
resistor when it is necessary and if an external brake resistor is connected to the drive. The
chopper operates when the DC link voltage exceeds a certain maximum limit. The voltage
rise is typically caused by deceleration (braking) of a motor. The user obtains and installs
the brake resistor when necessary.
4
DC connection (UDC+, UDC-).

Product variants
The drive has two product variants:
• Standard unit: drive with assistant control panel and RIIO-01 I/O & EIA-485 module
• Base unit: drive without control panel and without RIIO-01 I/O & EIA-485 module
(0J400+0L540) .
