3-9-5 Simple Positioning
You can achieve simple positioning by simple encoder feedback control. Fol-
lowing pages shows the related parameters to be set for the positioning.
Encoder wiring - The hardware overview about pulse train input is shown
below.
2-phase pulse input
Wire phase-A to EA terminal and phase-B to EB terminal. Since common ter-
minal 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
24 VDC. Assign EB in input terminal 7.
