App. 5.7 Parameter setting
App. 5.7.1 System option 1 setting
SSCNET communication method and control cycle is set by System option 1 (parameter No.0001).
SSCNET communication method is used for communication between a position board and connected units
such as servo amplifiers and SSCNET
/H method and SSCNET method are available. When using
MR-J3(W)- B series servo amplifiers, make sure to select the SSCNET method.
Control cycle is a cycle in which the position board controls command import, position control, status output,
and communication with servo amplifier. To set this cycle, use the control cycle (parameter No.0001). The
number of controllable axes differs depending on the control cycle.
(1) For MR-MC210/MR-MC240
Control cycle
Max. No. of axes
connected
Max. No. of axes
connected for each line
Controllable axis No.
0.88ms 16 axes 16 axes Axis 1 to 16
0.44ms 8 axes 8 axes Axis 1 to 8
(2) For MR-MC211/MR-MC241
Control cycle
Max. No. of axes
connected
Max. No. of axes
connected for each line
Controllable axis No.
0.88ms 32 axes 16 axes Axis 1 to 32
0.44ms 16 axes 8 axes Axis 1 to 16
Note. Keep connections within the max. No. of axes connected. When the max. No. of axes connected
are exceeded, system setting error (alarm No. 38, detail 01) will occur.
