•
An NC variable can be used as parameter instead of the constant.
•
A mathematical calculation cannot be used instead of a constant or an
NC variable.
•
The optional parameters do not need to be set.
•
The commas used to separate the parameters must always be used.
The zero offset values for "G50/G51," "G52" and the active zero offset
value
cannot
be written using the OTD command.
Example NC program - read zero offset table data
@100=OTD(,,,,1) Read total active X axis zero offset
•
X=OTD(1,0,2,4,1) Traverse X axis to the position which is
located in the ZO table in NC memory A
for process 0 of the 2nd zero offset table
for G54
•
@80=G(4) Read G-code of zero offset
@80=@80-50 Prepare value for the OTD command
•
@100=OTD(,,,@080,1) Read active X axis zero offset for the
ZO entry corresponding to the active
G-code (G50-G59)
Example NC program - write zero offset table data
OTD(,,,4,1)=SQRT(X*X+Y*Y) Assign the result of the declared calcula-
tion to the X axis entry for the offset per
G54 in the current NC memory for the
active process in the active zero point ta-
ble.
•
OTD(,,,4,1)=@100+OTD(,,,,1) Calculate the new X axis zero offset value
corresponding to G54 from the contents of
the variable 100 and the active X axis zero
offset.
CAUTION
The read zero point data is in machine coordinates.
