The control rack is supplied with 24 Vdc by the PS24 power supply, whose input is at 220 V, single-phase or three-
phase. The control rack is composed of the interface and power supply board (PIC2), one control board (MVC3),
the user’s function board (MVC4) and the fiber optic interface board (FOI3). The MVC3 board is responsible for the
motor and inverter control, and the MVC4 for the user’s interface tasks. Both boards are supplied with isolated
low voltages provided by the PIC2 board, where there are also opto-isolated digital inputs and relay outputs (220
Vac) for internal use of the MVW3000.
Optional Fieldbus communication and function expansion boards (EBA, EBB or EBC) can be connected to the
MVC4 control board. The connections between the MVC3 board and the power stages are made with fiber-optic
cables through the FOI interface boards.
ATTENTION!
Electronic boards have components sensitive to electrostatic discharges. Do not touch directly
on components or connectors. If necessary, touch the grounded metallic frame before or use an
adequate grounded wrist strap.
4.4 OUTPUT FILTERS
Depending on the installation conditions, it may be necessary the addition of an output filter. For drives with
cables between 200 and 500 m, it is recommended to use output filter on the motor phases. For drives with
long cables, above 500 m, or for motors not able to operate with PWM modulation (retrofitting applications), it is
recommended to use filter type 2 (contact WEG).
The available filter models follow the voltage and current informed in Table 2.3 on page 2-5 to Table 2.10 on
page 2-8 .
