I'm currently using compactrio and a NI-9401 module to read signals
from my quadrature encoder. While i was able to find example to help
with the velocity measurements, i'm yet to find one that would help me
reset the position to zero after every 360 revolution. I know the Z
signal should be used for that and i've tried some other examples
(including one in the labview example finder) but none of them works. I
have to manually click a reset button to get the encoder position to
zero. Please, is there anyone who knows how to do this? I also know the
new scan mode in labview 8.6 does this pretty easily but the scan mode
limits sampling rate (scan period) to 1ms using the scan engine but i
need at least 8.33 us because of the high rpm of the engine and high
resolution of the encoder (1440 pulse/s). Hence,my decision to use fpga
mode. Please any assistance will be highly appreciated. Thanks.
