(Note-1): The fully closed loop control servo amplifier can be set for the master axis only. It cannot be set for
the slave axis.
(Note-2): In the fully closed loop system, the servo amplifier can be set for the master axis only. It cannot be set
for the slave axis. Also, it cannot be used with the linear servo motors or direct drive motors. Refer to
each servo amplifier instruction manual for details.
This function uses the "Master-slave operation function" of servo amplifier. The Simple
Motion module controls master axis and the slave axis is controlled by data
communication between servo amplifiers (driver communication) without Simple
Motion module.
There are restrictions in the function that can be used by the version of servo amplifier.
Refer to each servo amplifier instruction manual for details.
The following shows the number of settable axes for the master axis and slave axis.
