With the G04 command, shifting to the next block can be delayed.
When commanded with a per minute feed mode (G94), shifting to the next
block can be delayed for the commanded minutes.
When commanded with a per rotation feed mode (G95), shifting to the
next block can be delayed till the spindle rotates for the commanded
times.
Dwell may always be performed by time irrespective of G94 and G95 by
parameter selection.

When a rapid traverse command is specified during automatic operation,
the function for positioning by optimum acceleration can be used to adjust
the rapid traverse rate, time constant, and loop gain, according to the
amount of travel for the block. This reduces the time required for
positioning and position check, therefore reducing the cycle time.
When rapid traverse is specified in automatic operation, the function
adjusts the rapid traverse rate, time constant, and loop gain to one of seven
levels, according to the amount of travel for the block. The relationship
between the amount of travel and the corresponding rapid traverse rate,
time constant, and loop gain is specified in parameters. This function is
not effective for cutting feed.
