Eight master axes can be set at most per one system of SSCNET III/H. The maximum number of slave
axes to each master axis is not limited. However, the total number of the master and slave axes should
be the maximum number of the servo amplifiers at most. In addition, when an SSCNET III/H
communication shut-off occurs due to malfunction of a servo amplifier, the malfunctioning axis and later
axis cannot be communicated. Therefore, the first amplifier from the controller via SSCNET III/H cable
should be master axis.
