(Note-1): The following restrictions are applied when the communication method is "SSCNET III"
• When the operation cycle is 0.2 [ms], set "0 to 3" for the axis select switch setting of the servo amplifier, and configure the system
setting.
• When the operation cycle is 0.4 [ms], set "0 to 7" for the axis select switch setting of the servo amplifier, and configure the system
setting.
For details, refer to the instruction manual of the servo amplifier.
(Note-2): When MR-J4W3-□B (Software version: A2 or earlier) or MR-J3W-□B is used, set 0.4 [ms] or more for the operation cycle.
