1) FG Terminal Block
This is the terminal block for frame grounding. Since this controller is made of plastic, it is
necessary to ground from this terminal block. Ground Type should be Class D (formally
Class 3 grounding = ground resistance 100

or less).
2) Power Connector
This is a connector to supply the 24V DC power (control power, actuator power and brake
control power supplies) and to input the emergency stop condition signals to this unit.
3) Absolute Battery Connector
This is a connector for future extension.
4) SIO Connector
It is the connector dedicated for the connection of a teaching tool such as PC software and
teaching pendant
5) 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)
The output from PLC is ignored at MANU and the data when switched to MANU is
maintained for the input to PLC.
Status Information
MANU
Manual Operation
：
An operation is available from a teaching
pendant or PC
AUTO
Automatic Operation
：
It can control the controller with Fieldbus
communication.
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.
