5vacon • 54 Control unit5. CONTROL UNITThe control unit of the AC drive consists of the control board and additional boards (optionboards) connected to the slot connectors of the control board.Figure 48. Location of control unit componentsWhen delivered from the factory, the control unit of the AC drive contains the standard control-ling interface - the control terminals of the control board and the relay board - unless other-wise specifically ordered. On the next pages you will find the arrangement of the control I/Oand the relay terminals, the general wiring diagram and the control signal descriptions.The control board can be powered externally (+24 VDC, 100 mA, ±10%) by connecting the ex-ternal power source to terminal #30, see page 56. This voltage is sufficient for parameter set-ting and for keeping the control unit active. Note however that the measurements of the maincircuit (e.g. DC-link voltage, unit temperature) are not available when the mains is not connect-ed.1 239058.emfLocations of essential control unit components:1 = Control terminals of the control board2 = Terminals of relay board; NOTE: There aretwo different compilations of relay boardsavailable.
