4. STARTUP
(2) Disabling control axis switch (SW2-2)
Turning "ON (up)" the disabling control axis switch disables the corresponding servo motor. The servo
motor will be disabled-axis status and will not be recognized by the controller.
(3) Switches for setting control axis No.
You can set the control axis No. between 1 and 64 by using auxiliary axis number setting switches with
the axis selection rotary switch. (Refer to (3) (c) of this section.)
If the same numbers are set to different control axes in a single communication system, the system will
not operate properly. The control axes may be set independently of the SSCNET III cable connection
sequence. The following shows the description of each switch.
(a) Auxiliary axis number setting switches (SW2-3 and SW2-4)
Turning these switches "ON (up)" enables you to set the axis No. 17 or more.
(b) Axis selection rotary switch (SW1)
You can set the control axis No. between 1 and 64 by using auxiliary axis number setting switches
with the axis selection rotary switch. (Refer to (3) (c) of this section.)

POINT
The control axis No. set to the auxiliary axis number setting switches (SW2-3
and SW2-4) and the axis selection rotary switch (SW1) should be the same as
the one set to the servo system controller. The number of the axes you can set
depends on the servo system controller.
For setting the axis selection rotary switch, use a flat-blade screwdriver with the
blade edge width of 2.1 mm to 2.3 mm and the blade edge thickness of 0.6 mm
to 0.7 mm.
When the test operation mode is selected with the test operation select switch
(SW2-1), the SSCNET III/H communication for the servo amplifier in the test
operation mode and the following servo amplifiers is blocked.
