7 Control Unit

7.1 Control Unit Components

The control unit of the AC drive contains the control board and additional boards (see

illustration 23

) connected to the 5 slot

connectors (A to E) of the control board. The control board is connected to the power unit through a D-connector or fiber optic cables
(FR9).

Illustration 23: Basic and Option Slots on the Control Board

The control unit of the delivered AC drive contains the standard control interface. If the order included special options, the AC drive is
delivered according to the order. The next pages contain information on the terminals and general wiring examples. The type code
shows the I/O boards that are installed at the factory. For more information on the option boards, see VACON

manual.

The OPTA1 basic board has 20 control terminals, and the relay board has 6 or 7. The standard connections of the control unit and the
descriptions of signals are shown in

7.3.2 Control Terminals on OPTA1

.

For instructions on how to install the control unit that is not attached to the power unit, see VACON

NXP IP00 Drives Installation

Manual.

7.2 Control Voltage (+24 V/EXT +24 V)

It is possible to use the drive with an external power source with these properties: +24 V DC ±10%, minimum 1000 mA. Use it to
externally power up the control board, and the basic and option boards. The analog outputs and inputs at OPTA1 do not work with
only +24 V supplied to the control unit.

Connect the external power source to one of the 2 bidirectional terminals (#6 or #12), see the option board manual or VACON

®

NX I/O

Boards User Manual. With this voltage, the control unit stays on and parameters can be set. The measurements of the main circuit (for
example, the DC-link voltage, and the unit temperature) are not available when the drive is not connected to mains.
