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.

3-1-2 EXT. CN connector signals

The EXT. CN connector of the SRCP controller has 4 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.

Pin No.	Signal name	Description	Pin No.	Signal name	Description
1	EMG1	Emergency stop input 1 (used with	2	EMG2	Emergency stop input 2 (used with
		EMG2)			EMG1)
