9.8 Driver Communication Function
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.
*1 The fully closed loop control servo amplifier can be set for the master axis only. It cannot be set for the slave axis.
*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.
