2-6. External control pin assignments
2-6-1. External control terminal (controller AD-IF connector)
When performing external control, see "Table 2-7 External control signal connection
equivalent circuits" and connect the external control terminal to an external control device such
as a PLC.
• When connected to the controller
Table 2-5 External control terminal pin assignments when connected to the controller
