Control unit
The control unit of the inverter consists roughly of the control board and additional boards
(see Figure 4-7a and Figure 4-7b) connected to the five
slot connectors
(A to E) of the
control board. The control board is connected to the power unit through a D-connector (1).
Figure D-7a Figure D-7b
Usually, when the inverter is delivered from the factory, the control unit includes at least
the standard compilation of two basic boards (I/O board and relay board) which are
normally installed in slots A, B, and D. On the next pages you will find the arrangement of
the control I/ O and the relay terminals of the two basic boards, the general wiring diagram
and the control signal descriptions. The I/O boards mounted at the factory are indicated in
the type code.
