NX5001 — Incremental Encoder Input
The NX5001 manages a 24 Vdc incremental encoder, acquiring traces A/A#, B/B# and the Z/Z# index. It also provides a latch input for position capture (rising and falling edge), measures the time between latch and Sync0 (µs resolution), and the time between consecutive Index signals.
