General-Purpose Output (Do0 To Do4); Feedback Pulse Output - Yamaha SRCP User Manual

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.
Function name
Alarm output
Return-to-origin complete output
Servo-ON status output
Zone output

3-3-3 Feedback pulse output (PA±, PB±, PZ±, PZM±)
This outputs current position data as differential output.
