How
to set
imaginary phase-C shiting values
(
i
)
When the machine
zero-point
and
dc.eleration
.limit switch are
at
arbi¬
trary
positions.
(D Set the
parameter.
As
temporary
setting, set
the reference
point
return
traveling
distance
(pm4451
to 4455)
to 0
and the imaginary
phase-C
shift distance
(pm4551
to
4555)
to
1000.
(%)
Execute
reference point
return.
®
When
the tool
stops
before the machine zero-point, the distance from
the stopped position"
to
the machine
zero-point is added
to
the
imagi¬
nary
phase-C
shift distance.
.
When it
stops
after the machine
zero-point,
the distance from the
stopped position
to
the machine
zero-point is
subtracted
from the
imaginary phase-C shift
distance.
•
0
Inching adjustment
to
the actual machine zero-point is possible
at
the
imaginary phase-C shit distance or reference point
return traveling
distance.
(
ii
)
When the machine
zero-point
and deceleration limit switch
are
at
a
distance of
1/2
of the ball screw pitch
"
Perform
adjustment assuming
that the machine zero-point described
above
(c)
is
at a
distance of
1/2
of the ball
screw pitch. Inching
adjustment
to
the actual machine
zero-point is possible
at
the refer¬
ence point
return
traveling
distance.
