Introduction
The Positioning Unit KD71 (hereafter abbreviated as KD711, is
used for high-precision positioning control as one of the input/
output
peripherals of the
MELSEC-K1,
K2,
K O J .
The KD71 has a microprocessor,
whose output is a positioning
pulse sequence, including acceleration and deceleration.
The output can be combined with various kinds of servo
control drive units to perform positioning for a wide range
of industrial equipment.
Features
:
1.
Full digital control
0
The use of a high-speed microprocessor has made possible small
size and high performance, with high reliability.
2 .
One unit performs 2-axis control
With a single positioning unit, independent 2-axis control o r
simultaneous 2-axis control is possible.
3 .
Includes linear interpolation function.
A
2-axis linear interpolation function is included in the unit.
4 ,
Includes backlash compensation function.
The backlash compensation function makes possible high-preci-
sion positioning possible.

Since the KD71 operates with pulse-sequence output, it can be
used with DC servo motors, AC servo motors, stepping motors,
and other drive units.
