MECHATROLINK - Technical overview
MECHATROLINK is an open field network that connects a controller with a variety of devices. High-speed communications and data synchronization are provided to increase system speed and provide advanced functionality. Moreover, MECHATROLINK uses simple cable connections to reduce wiring, downsize the system, and enable easy system expansion.
Because MECHATROLINK is an open network, there are many different MECHATROLINK compatible devices available on the market that can be flexibly combined to suit your application. Furthermore, you can freely develop your own master and slave devices for MECHATROLINK. Using MECHATROLINK is highly recommended to quickly achieve a variety of mechanical operations simply and at a low cost.

Positioning of MECHATROLINK
MECHATROLINK is positioned as a Field Network. A Field Network is a network that drives control elements of control system such as I/Os and actuators, and allows devices for input control information to be connected.

MECHATROLINK has been used in diverse applications, such as those for machine tools, industrial robots, machines for mounting electronic parts and machines for transferring. It is especially suitable for synchronous and interpolated motion control. MECHATROLINK enables control of torque, positioning, and velocity, all of which are necessary to control your machine. Also, the control modes for velocity, torque, and position can be switched while the machine is running, so you can perfectly control the machine’s complex motions.

Network Reliability
MECHATROLINK is the only field network that utilizes a “data retry” function processed and executed by the communications chip.
The communication chip resends data that has become corrupted by noise, within the same communication cycle. This results in the communications having a strong resistance to noise. Since this “data retry” function is processed and executed by the communications chip, application-sided code is not necessary to take advantage of this feature.

MMA has grown to over 2000 members globally and membership is free of charge. Join MMA as a Registered Member today to download the communication specification and access all the technical materials at
