Latch input<br />
Specification<br />
One channel (Phase A, Phase B, Index pulse)<br />
Phase A & B: 5V differential input (RS-422 compatible), non-insulated.<br />
Maximum frequency 4MHz.<br />
Index pulse: 5V/12V/24V photo coupler input. Maximum frequency<br />
500kHz (pre-quadrature. This signal is used for external encoder latch.<br />
Quadrature, pulse and direction, up/down<br />
Latch on index pulse or DI_01 digital input.<br />
<strong>Hardware</strong> latency: 5s or less (index pulse)<br />
Two RS-422 compatible inputs are provided for encoder phases A and<br />
B. One position latch input which supports a 5V, 12V, or 24V digital input <br />
signal is provided.<br />
