Wiring for Encoder Following
(Encoder power can be supplied from the +5V OUT terminal on IN/OUT 1 if the
encoder requires no more than 100mA)

Lower Speed, Differential Digital Inputs
All STAC5 drives include two lower speed inputs called X3/EN and X4. They accept 5-24 volt single-ended or differential signals, but
only at lower speeds than STEP and DIR. You can use these inputs with
Wait Input, If Input, Feed to Sensor, Seek Home
and other such
commands. -Q models include four additional differential inputs on the IN/OUT2 (OPT2) connector called IN1, IN2, IN7 and IN8. IN1
and IN2 can be used for connection to sensors and other devices. IN7 and IN8 are normally used for end of travel limit switches, but can
be used for registration sensors, etc.
Connection diagrams follow.
