8) Fan Unit
This is the fan unit to cool down the controller. This unit can be detached from the controller
for maintenance by removing the screw on the hook in the front of the controller.
9) Operation Mode Setting Switch
This is a switch to change the operation mode between Automatic Operation (AUTO) and
Manual Operation (MANU). The operation modes are provided to avoid the duplication of
the SIO (Serial) communication operation using PC software or a teaching pendant
(described as teaching tool from now on) and the operation with Fieldbus or PIO (Parallel
I/O)
For the details of the mode selection, refer to 11) System I/O Connector.
10) SIO Connector
This is a connector dedicated for the teaching tool connection.
11) System I/O Connector
This is a connector for additional devices for the input of all-axes external emergency stop,
AUTO/MANU switchover and external regenerative resistor.
It is connected in a series with the operation mode setting switch (AUTO/MANU) on the front
panel. The controller can be in the following modes by the mode selection on each switch
and teaching tool.

Note 1 : “Accept PIO Startup” and “Prohibit PIO Startup” are the functions to select the
operation mode of when the teaching tool is connected.
Note 2 : Refer to 2.3 [4] for the details.
Caution : (1) If “Accept PIO Startup” is selected on the teaching tool, the AUTO operation
becomes available no matter the condition of the front panel or external
switchover signal input, thus attention may have to be paid. In such a
condition, the actuator may get activated by following the signal from the host.
(2) The information of “Accept PIO Startup” or “Prohibit PIO Startup” is remained
when the teaching tool is removed from the controller. Do not fail to select
“Prohibit PIO Startup” when removing the teaching tool after finishing the
teaching operation or debugging.
