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
User 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
7.2 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
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.
