Servo parameter
Set the following parameters for the axis to execute the driver communication. (Refer to each servo amplifier instruction
manual for details.)
[MR-J3-_B/MR-J3-_BS/MR-J3-_B-RJ006 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 MR-J3-_B/MR-J3-_B-RJ006 use, it is not necessary to change the setting since the initial value is disabled. However, it is required to
set disabled since the initial value is enabled at MR-J3-_BS use.
• 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 (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)".
