OUT (leading pulse output) and DIR (trailing pulse output)
The OUT (leading pulse output) signal and the DIR (trailing pulse output) signal are generated.
The motor is operated (rotated) in the positive direction (clockwise), when there is a phase difference of
+90° between DIR (trailing pulse output) and OUT (leading pulse output). On the other hand, the motor
is operated (rotated) in the negative direction (counterclockwise), when there is a phase difference
of -90° between DIR (trailing pulse output) and OUT (leading pulse output).

General-purpose input signals
This product has general-purpose input signals (IN1 - IN7) in addition to limit input and encoder input
signals.
IN1 - IN7 (General-purpose input signals)
IN1 - IN7 (general-purpose input signals) can be used to read data from I/O ports. Since these are
independent of motor control, they do not affect pulse output even during motor operation. As seven
signals are provided for each axis, they can be used to input the alarm signal or positioning completion
signal from the motor driver unit. IN1 - IN5 can be switched to serve as the alarm input, positioning
completion input, deceleration (decelerated stop) input, counter latch input and positioning control start
input respectively. The input logic can also be changed by software.
ALM (Alarm input signal)
ALM is the input signal to detect the alarm signal from the motor driver. The input logic can be changed
by software.
INP (positioning completion signal)
INP is the signal to detect the positioning completion signal from the motor driver unit. The input logic
can be changed by software.
SD (deceleration (decelerated stop) input)
SD is a signal to detect the position at which to start deceleration. The input logic can be changed by
software.
