No. Name
SSCNET III cable connector (for the first axis).
2) CNA Connect an SSCNET III cable. ( Page 46, Section 6.5.1)
Connect the Motion controller, a servo amplifier for the first axis, or the head module of the preceding station.
SSCNET III cable connector (for the second axis).
Connect an SSCNET III cable. ( Page 46, Section 6.5.1)
3) CNB
Connect a servo amplifier for the second axis or the head module of the following station.
If the head module of own station is the last station, cover the connector with a cap.
4) Serial number display Displays the serial number printed on the rating plate.

This switch controls the operation of the head module.
Resets the head module or switches it to test mode.
Operate the switch with your fingers. Use of a tool such as a screw driver may damage the switch.
• Reset method
1.
Do not release your hand from the switch while it is in the RESET/TEST position.
2.
RESET/
TEST
3.
5) Switch
The switch automatically returns to the STOP position when your hand is released.
• Test procedure: For details of the test mode, refer to the explanation on the test mode. ( Page 44, Section 6.4)
Stops the data transfer between the link devices of the head module (cyclic data from the Motion controller) and head
module devices. (Stops the transfer while performing cyclic transmission with the Motion controller, and stops the output.)
Stopping the data transfer stops sending the input/output information of modules, connected to the head module, to the
Motion controller. The STOP switch is used when performing a debug operation between modules connected to the head
module and external devices.
The following shows an example of a debug method with external devices using the STOP switch.
STOP
(1)
(2)
(3)
(4)
Starts the data transfer between the link devices of the head module (cyclic data from the Motion controller) and head
module devices.
RUN
The output from the Motion controller is output from a module connected to the head module.
The input from the module connected to the head module is input to the Motion controller.
Hold the switch in the RESET/TEST position for 1 second or more.
Switch
Check that the ERR. LED flashes several times, and turns off.
: Flashing
Flashes several
times then
turns off.
Set the switch to the STOP position.
Switch
Set the switch to "STOP".
Data transfer is stopped between the link devices of the head module and head module devices and the devices are
separated from the Motion controller control.
Conduct an input/output test between the module connected to the head module and the external device. Since the
data transfer is stopped, the input/output status data are not sent to the Motion controller.
When the test is complete, write parameters to the head module and start the system operation.
