speed Input
With eight high-speed inputs X00-X07, the H3U standard model supports pulse input frequency up to 200 kHz
and provides single-phase unidirectional counting, single-phase bidirectional counting or A/B phase counting, and
high-speed interrupt functions.
With three high-speed inputs X, Y, and Z axes, each with two differential inputs, H3U-PM supports pulse input
frequency up to 200 kHz and provides pulse+ direction, A/B phase, and CW/CCW high-speed pulse counting and
speed measurement functions.
