(5) Difference between absolute value command and incremental value command
(6) Feed rate for tapping cycle and tapping retract
The feed rates for the tapping cycle and tapping retract are as shown below.
(a) Selection of synchronous tapping cycle/asynchronous tapping cycle

information.
If the value is smaller than the
speed rotation speed, the
speed rotation speed value will
be valid even during retract.
If the spindle rotation speed is
not 0 during retract, the tap
retract override value will be
invalid.
