Unit Functioning and Operation Overview
Unit Combinations for Positioning Control
Interfaces provided with the positioning unit
In addition to pulse instruction output for the motor driver, the positioning unit is
equipped with home input, near home input terminals, over limit input (+), over
limit input (-), positioning control start input (timing input) for JOG positioning
operation, and deviation counter clear output for the servo driver.
Use input unit and output unit for PLC safety circuit and control
signal interfaces.
In addition to the positioning unit, an input unit and output unit are used in
combination for connections between the driver and external output such as servo
ON signals.
Number of output pulses counted by internal high - speed
counter.
The number of pulses output is counted as an absolute value by an internal high .
speed counter, which counts them as the “elapsed value”.
Counting range: - 2,147,483,648 to +2,147,483,647 (signed 32 - bit)

If the elapsed value exceeds the maximum (minimum) value, the value returns
automatically to the minimum (maximum) value and continues from that point.
The motor does not stop if this occurs, and no error occurs.
