1-1 Overview
The CJ1W-MCH72 is a Trajexia-style motion control unit that can be
connected to a CJ1-series PLC. It acts as an interface between PLC systems
and Trajexia-style motion control systems.
Trajexia is the OMRON motion platform that offers you the performance and
the ease of use of a dedicated motion system. It maximum flexibility and
scalability. At the heart of Trajexia lies the TJ1 multi-tasking motion
coordinator. Powered by a 32-bit DSP, it can do motion tasks such as e-cam,
e-gearbox, registration control and interpolation, all using simple motion
commands.
The CJ1W-MCH72 has the following features:
• A MECHATROLINK-II connection for a MECHATROLINK-II network with
up to 30 axes. The motion cycle time is selectable: 0.5 ms, 1 ms, 2 ms or 4
ms.
• An Encoder Interface connection. It supports the main absolute encoder
protocols allowing the connection of an external encoder to the system.
• The possibility to exchange analogue and digital input and output data with
the PLC CPU.
• A wide choice of rotary, linear and direct-drive servos as well as Inverters
are available to fit your needs in compactness, performance and reliability.
The Inverters connected to the MECHATROLINK-II are driven at the same
update cycle time as the Servo Drivers.
Note The Trajexia system supports 3 kinds of MECHATROLINK-II slaves: Servo Drivers,
Inverters and I/Os.
The CJ1W-MCH72 only supports 2 kinds of MECHATROLINK-II slaves: Servo Drivers
and Inverters. It does not support I/Os.
