5.4 Wiring Electronic Lineshaft and the Alignment Inputs
The two alignment inputs can each come from either the marker pulse from an encoder or from an external
sensor. The alignment inputs need to be wired to the marker (Z) pulse inputs of the dual input encoder card
(ex. PG-W2). Marker pulse input channels require a line driver type circuit. Wire the master alignment input
into terminals 14 and 15 of the PG-W2. Wire the follower alignment input into terminals 7 and 8 of the PG-
W2. For other dual input encoder cards, consult their installation guide for exact terminals. Figure 5 below
details the wiring of the PG-W2 option card.
