Parameter
This validates the synchronous tap. When not validated,
the conventional tap cycle is validated.
This selects whether the synchronous tap is carried out
with the constant time constant method or constant
inclination method.
This sets the time constant of the position command
during constant time constant synchronous tap. Set as
follows when the start time during operation by S
command to the possible tap max. speed is set to t.
When the tap accuracy is given priority
.......... tap-tl
When the tap cycle time is given priority
.......... tap-tl
This sets the position loop gain during synchronous tap.
This must be set to the same value as the spindle
parameter PGT.
