This function uses the "Master-slave operation function" of servo amplifier. The Motion
CPU controls the master axis and the slave axis is controlled by data communication
(driver communication) between servo amplifiers without going through the Motion
CPU.
This function is used for the case such as to operate the ball screw controlled by
multiple axes via the belt.
There are restrictions in the function that can be used by the version of the servo
amplifier.
Refer to the "Servo amplifier Instruction Manual" for details.
The following shows the number of settable axes for the master axis and slave axis.

32 axes 1 axis to 8 axes
16 axes 1 axis to 4 axes
POINT
Driver communication function is only valid in MR-J3- B and MR-J4- B.
MR-J4W- B and MR-J3W- B cannot be used.
Nor can MR-J4W- B be used in MR-J3- B compatibility mode.
Ver.! : Refer to Section 1.5 for the software version that supports this function.
