Format and Functions
of
Operating Data
The following three blocks of data
are
required for positioning using
the AD71. This data
is
written to the buffer memory which will be
explained in Section
3.5
(page
3-30).
o
Parameters
o
Zeroing data
o
Positioning data
Operating data
is
written using:
1)
AGGPP or AD71TU.
. .
.For details, refer to the SWOGP-AD71P
or AD71TU Operating Manual.
2)
Sequence program.
.
.
.
.For details, refer to Chapter 6.
It
is
necessary to
set
data for the two
axes
(X
and
Y
1.
3.4.1
Parameters
This
is
the general information required for positioning. Table
3.5
gives
a
list
of all the parameters which must be
set
for the AD71.
Initial parameter values
If parameters are not
set
or
an error
is
found (for example parameter
is
outside the allowed
setting
range),
all
data defaults to the values
shown in Table
3.5
and the faulty
set
of parameters will remain in
the buffer memory.
Parameters are checked when:
1)
the
power
is
switched on;
2)
parameters are transferred from the A6GPP to the AD71;
3)
"PC
ready signal" from the
PC
CPU to
the
AD71 switches from
4)
(1) zeroing,
(2)
positioning,
(3)
jog operation, or
(4)
inching has
"off"
to
"on"; or
been selected in A6GPP
test
mode.
Error code and error detection signal are not given for the "power on"
parameter check.
