It is possible to suspend the execution of axis move commands specified in the
next block for the specified length of time (dwell period).
Format
G04 X...; or G04 P...;
X: Dwell time (decimal point representation)
P: Dwell time (integer representation)
There are two different methods how to execute the programmed dwell time:
MD $MC_EXTERN_FUNCTION_MASK
Bit2 = 0: Dwell always in seconds [s]
Bit2 = 1: Dwell in seconds (G94 mode) or spindle rotations (G95 mode)
The execution of programmed commands is suspended for the length of time in
the feed per minute mode (G94) and a number of spindle rotations in the feed per
revolution mode (G95) determined by the address X or P by specifying G04 X...; or
G04 P...;
The block used to determine dwell is not allowed to contain commands other than
G04 commands.
