Chapter 3 I/O Interface - Yamaha ERCX Series User Manual

Chapter 3 I/O INTERFACE
The ERCX series has an I/O interface consisting of emergency stop inputs, interlock, 7 dedicated command inputs,
3 dedicated outputs, 16 general-purpose inputs, 13 general-purpose outputs, etc. This I/O interface allows exchang-
ing commands and data between the ERCX series and external equipment. This I/O interface can also directly
connect to and control actuators such as valves and sensors. To construct a system utilizing the features of the
ERCX series, you must understand the signals assigned to each terminal on the I/O connector and how they work.
This chapter 3 covers this fundamental information.
This chapter also provides examples of I/O circuit connections and timing charts for expanding the system by using
3
a PLC or similar devices. Refer to these diagrams and examples when creating sequence programs.
Terms "ON" and "OFF" used in this chapter mean "on" and "off" of switches connected to the input terminal when
referring to input signals. They also mean "on" and "off" of output transistors when referring to output signals.
