3.8.1 MECHATROLINK-
II
Communications
Outline
MECHATROLINK-II is a field network that makes it possible for one factory automation controller (C1
master station) to control decentralized multiple factory automation devices (slave stations) such as
servo drives, inverters, and I/O modules.
Configuration
• Bus connection with one C1 master station and a maximum of 30 slave stations
• Install terminators at both ends of the network cable to reduce signal reflection.
• Connect repeaters for a network with a total distance exceeding 30 m, regardless of whether the
number of slaves is 17 or more or 16 or less.
3.8.2 Wiring Specifications
Terminators
Install terminators at both ends of the network cable to reduce signal reflection, some Mechatrolink
controllers already have a terminating resistor built-in.
Repeaters
A repeater is needed in the network, when the total distance between stations exceeds 30 m, or when
the number of slave stations is 17 or more.
