5. CONTROL UNIT
58
When you receive the AC drive, the control unit contains the standard control interface. If you included special options in your
order, the AC drive will be as in your order. On the next pages, you will find information on the terminals and general wiring ex-
amples.
It is possible to use the drive with an external power source with these properties: +24 VDC ±10%, minimum 1000 mA. Connect
the external power source to terminal 30. This voltage is sufficient to keep the control unit on and for you to set the parameters.
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.
5.2 CONTROL UNIT CABLING
The control board has 22 fixed I/O terminals, and the relay board has 8. You can see the standard connections of the control
unit and the descriptions of signals in Fig. 25.
5.2.1 SELECTION OF THE CONTROL CABLES
The control cables must be a minimum of 0.5
㎟
screened multicore cables. See more on the cable types in Table 15 The se-
lection of the correct cable. The terminal wires must be a maximum of 2.5
㎟
for the terminals of the relay board and other
terminals.

5.2.2 CONTROL TERMINALS AND DIP SWITCHES
Here you see the basic description of the terminals of the I/O board and the relay board. For more information, see 8.1 Technical
data on control connections.
Some terminals are assigned for signals that have optional functions that you can use with the DIP switches. See more in
