9.8 Driver Communication Function
[MR-J4-_B use]
n: Axis No. - 1
*1 When the slave axis is not allocated for the master axis, only the master axis operates independently.
*2 At slave setting, set only "Driver communication setting Master axis No. selection 1 for slave (PD20)" in the master axis No. selection
normally.
• The servo parameters are transmitted from Simple Motion module to servo amplifier after power supply ON
or reset of the CPU module. Execute flash ROM writing of Simple Motion module after writing the servo
parameter to buffer memory, and then turn the power supply ON or reset the CPU module.
• The servo parameters for driver communication setting (PA04, PD15 to PD17, PD20) become valid by
turning the servo amplifier's power supply OFF to ON. Turn the servo amplifier's power supply OFF to ON
after executing the above shown in the 1st bullet. Then, turn the system's power supply ON again or reset
the CPU module.
• In the driver communication function, the torque generation direction for slave axis can be set in "Rotation
direction selection/travel direction selection (PA14)".
