Solid
tap-related
functions
By
adding
the
solid
tap
functions
(optional),
the
following
functions
are
added
or
modified.
(a)
Display
of
servo
position
deviation
The
servo
position
deviation
display
screen
during
the
solid
tap
mode.indicates
the
spindle
servo
position
deviation value
on
X-axis,
and
the
number
of
synchronization
error
pulses
of
spindle
and
Z-axis
on
Y-axis.
(Z-axis
servo
position
deviation
value
is
indicated
on
Z-axis.)
However,
the
pulse
display
on
Y-axis
is
not
exact
when
in
the
continuous
mode
(single-block
OFF).
Also
note
that
when
parameter
Pm4015
D6=l,
the
peak
values
of
synchronization
error
pulse
can
be
displayed
on
X-and
Z-axis.
(X-
,
axis:
positive
peak
value;
Z-axis:
negative
peak
value)
(b)
Error
detection
during
solid
tap
By
setting
parameter
Pm4015
D5
to
"1.”
it
is
possible
to
place
rapid
feedrate
commands
during
solid
tap
(X,
Y
positioning,
Z-axis
positioning)
into
the
error
detect
OFF
mode.
When
this
parameter
is
turned
ON,
the
cycle
time
can
be
reduced.
I
*n
this
case-
however,
control
advances
to
the
Z-axis
block
immediately
after
X,
Y
positioning
pulse
distribution
is
completed,
so
care
should
be
taken
for
the
program.
