3-3 Output Signal Description

3-3-2 General-purpose output (DO0 to DO4)

These general-purpose outputs are available to users for freely controlling on/off operation in a pro- gram.

These outputs are used in combination with an external 24V power supply, to drive loads such as solenoid valves and LED lamps. These outputs of course, can be directly connected to a PLC input circuit.

All general-purpose outputs are reset (turned off) when the SRCP controller is turned on or the program is reset.

*When PRM33 ("Operation at return-to-origin complete" parameter) is set to 1 or 3, DO4 does not turn off even if the program is reset. Similarly, when PRM46 ("Servo status output" param- eter) is set to 1, DO3 does not turn off even if the program is reset.

General-purpose output (DO0 to DO4) can be used to perform the following specific functions by parameter setting.
