text: <s>[INST] Encoder 845H I got an 845H encoder connected to a 1769-HSC module, when I power up the encoder my reading increase for CW rotation and decrease for CCW rotation, I just need the opposite, I connected encoder channel A to module channel A1, some clue? Thanks. [/INST] If you are using quadrature mode, you may swap the A and A- leads with the B and B- leads (page 23 of the below indicated manual)...the count direction is determined by the phase relation of inputs A and B. If A leads B, the counter increments. If B leads A, the counter decrements. Or you may use the DirectionInvert bit to change the counting direction, leaving the encoder connected as is... :smileysurprised: take a look to the -HSC User Manual at page 18 and page 25 to see various options... Hope this helps… - fuzzy logic \\n </s>
