Jumper selections on the OPTA1 basic board
You can change the functions of the AC drive to make them better agree with your requirements. To
do this, change some positions for the jumpers on the OPTA1 board. The positions of the jumpers
set the signal type of analogue and digital inputs.
On the A1 basic board, there are 4 jumper blocks: X1, X2, X3 and X6. Each jumper block contains 8
pins and 2 jumpers. See the possible jumper selections in the figure below.
