5.8 Dwell time, delay (G4, WRTPR)

5.8 Dwell time, delay (G4, WRTPR)
Function
You can use G4 to interrupt workpiece machining between two NC blocks for the
programmed length of time, e.g., for relief cutting.
The WRTPR command does not generate an executable block in continuous-path mode.
Thus, it can be used to delay the machining job without interrupting continuous-path mode.
Programming
G4 F...
Or
G4 S...
Write string-type statement with next block in main run:
WRTPR(string, parameter) if parameter = 0 or not specified.
Programming in a separate NC block
Parameters
G4
F...
S...
WRTPR
Parameter = 0
224
Activate dwell time, G4 interrupts the continuous-path mode
Time specified in seconds
Time specified in revolutions of the master spindle
Either append a job in continuous-path mode to the next executable block
or execute it immediately.
Write to log with next executable block (following a delay). This is the
default response so there is no need for parameterization. Continuous-path
mode functions as normal.
