MECHATROLINK-II Communications Connections
The following example shows a PCU connected with several Servo Drives
with the MECHATROLINK-II Connection Cables.
Note When not using Repeaters, the maximum total length of the Connection
Cable (L1 + L2 + ... + Ln) is 50 m when using fewer than 16 axes or 30 m
when using 16 axes.
MECHATROLINK-II
Connection Cable Length The maximum total length of the Connection Cables depends on the number
of MECHATROLINK devices (Servo Drives) being connected, as shown in the
following table.
Note The number of devices in the table for when Repeaters are used does not
include the Repeaters. For example, if using one MECHATROLINK device
between the PCU and the Repeater and 15 MECHATROLINK devices
between the Repeater and the Terminator, there will be 16 MECHATROLINK
devices and the maximum total cable length is 100 m.
Note Always turn OFF the power supply to the PCU and Servo Drives before con-
necting or disconnecting MECHATROLINK-II Connection Cables or the Termi-
nator.
