3-1 I/O Signals
The SRCP controller has two I/O interface connectors (EXT. CN and I/O. CN) as a standard feature.
The EXT. CN is used for emergency stop input and 24V power input for I/O control. The I/O. CN is
used for interlock signal input, dedicated command input, dedicated output, general-purpose input
and output, and feedback pulse output.
3-1-1 I/O. CN connector signals
The I/O. CN connector of the SRCP controller has 40 pins, with an individual signal assigned to each
pin. The following table shows the pin number as well as the name and description of each signal
assigned to each pin. For a more detailed description of each signal, refer to "3-2 Input Signal De-
scription" and onwards.
