3.3 Encoder feedback signals EA, EB and EZ
The PCI-8136M provides 6 differential pulse inputs with 2500V rms isolation,
and each pair of EA, EB, and EZ is related to one motion axis. The pulse
mode is software programmable to be AB-phase, CW/CCW, or
Pulse/Direction, and the counter speed goes up to 2 MHz. The following
table is the pin assignments for encoder counters.
