Jumper selections on the OPT-A1 basic board
The user can customise the functions of the inverter to better suit his needs by selecting certain
positions for the jumpers on the OPT-A1 board. The positions of the jumpers determine the signal
type of analogue and digital inputs.
On the A1 basic board, there are four jumper blocks (X1, X2, X3 and X6) each containing eight pins
and two jumpers. The selection possibilities of the jumpers are shown on page 58 (Figure 6-21).
