When delivered from the factory, the control unit of the AC drive contains the standard controlling
interface - the control terminals of the control board and the relay board - unless otherwise spe-
cifically ordered. In the following pages you will find the arrangement of the control I/O and the relay
terminals, the general wiring diagram and the control signal descriptions.
The control board can be powered externally (+24VDC ±10%, 1000mA) by connecting the external
power source between terminal #6 and GND, see chapter 5.3.2. This voltage is sufficient for param-
eter setting and for keeping the control unit active. Note however that the values of the measure-
ments of the main circuit (e.g. DC-link voltage, unit temperature) are not available when the mains
is not connected.
