Pulse train input (see page 16)
•Mode 0 : 90 degree phase difference pulse
•Mode 2 : Forward pulse/Reverse pulse
•Mode 1 : Forward/Reverse signal, pulse train
ON/OFF of the terminal resistance on the option
board can be done by the dip switch.
(Built in terminal resistance 150 ohm)
Mode setting is done at the pulse mode selection

Open collector outputs
(Refer to a main body
intelligent input
terminal)
(Note 1): Valid when LAC is assigned to an intelligent input terminal of the main body (SJ300).
(Note 2): Valid when POK is assigned to an intelligent output terminal of the main body (SJ300).
(Note 3): Refer to the code setting method of SJ300
