Simple Positioning

Encoder wiring – The hardware overview about pulse train input is shown bas below.
Pulse input types
90° ph. difference 2-ph. pulse
Single phase pulse + direction
Single phase pulse

2-phase pulse input

Wire phase-A to EA terminal and phase-B to EB terminal. Since common terminal of EB is
same as other inputs, use all the input terminals as source logic (PNP open collector or
voltage output type). Voltage of EB should be 18 to 24VDC. Assign EB in input terminal 7.
