4.3 External Encoder Interface
Two RS-422 compatible inputs are provided for encoder phases A and
B. One position latch input which supports a 5V, 12V, or 24V digital input

signal is provided.
Encoder Input Circuit (PILC refers to positive input side of sensor)
Item Specification
Number of
channels
One channel (Phase A, Phase B, Index pulse)
Input circuit
Phase A & B: 5V differential input (RS-422 compatible), non-insulated.
Maximum frequency 4MHz.
Index pulse: 5V/12V/24V photo coupler input. Maximum frequency
500kHz (pre-quadrature. This signal is used for external encoder latch.
Counter modes Quadrature, pulse and direction, up/down
PIL Latch input Hardware latency: 5 s or less, sinking input
DI_01 Latch Input Hardware latency: 600 s or less, sinking input
