1-1 Features
The Position Control Unit is a CS/CJ-series CPU Bus Unit. The Position Con-
trol Unit (PCU) receives commands from the CPU Unit's internal Auxiliary
Area and outputs positioning commands to MECHATROLINK-II Servo Drives.
MECHATROLINK is a registered trademark of MECHATROLINK Members
Association.
Compatible with the
MECHATROLINK-II High-
speed Field Network A MECHATROLINK-II high-speed (10 Mbps) communications interface is
used to control Servo Drives for up to 16 axes with a single CS/CJ-series Unit.
Shielded twisted-pair cables in daisy-chain formation make wiring simple and
enable multi-axis systems that require less wiring and are smaller in size.
High-speed, High-
precision Control Using
Data Communications Optimal motor performance can be achieved by transmitting data using com-
munications between the Programmable Controller (PLC) and Servo Drives,
without having to set an upper limit for the designated speed. High-speed and
high-precision position control using high-resolution motors are possible.
Position Control (Direct
Operation) Positioning can be performed simply by directly setting the target position and
target speed from the CPU Unit. Positioning to either absolute or relative posi-
tions is also possible. Interrupt feeding is also supported. With interrupt feed-
ing, positioning is continued for a specified amount after an interrupt input
signal is received, and then the axis is stopped.
Speed Control and Torque
Control The Servo Drive's speed and torque can be controlled by directly specifying
the target speed and torque from the CPU Unit.
Compatible with
Servomotors with
Absolute Encoders The PCU is compatible with Servomotors that have absolute encoders. Using
such Servomotors eliminates the need to repeatedly perform origin searches.
Transfer Data between
Host PLC and Servo Drive The Servo Drive's parameters and monitors can be set from the CPU Unit. All
the data for the multi-axis system can be centrally controlled from the host
PLC. This removes the difficulty in starting up devices or setting data when
replacing a Unit.
