External Data Input
External Tool offset
These signals provide for changing the tool compensation value via the
PMC. When the offset number is specified by a part program, data input
from the PMC is added to the offset value. The offset value can also be used
as input data itself by specifying the input signal.
When the machine tool is equipped with automatic tools or workpiece
measuring functions, the offset value can be corrected using this function, by
inputting the error from the correct value into the CNC via PMC.
If the tool compensation value is externally input when offset number 0 is
specified in a part program (an offset cancel) in the lathe turning machine,
the workpiece coordinate system shifts by the entered quantity.
The external tool offset range is +/
- 79999999.
NOTE
1 When data is out of range, the alarm DS1128 occurs.
2 When the data of ineffective optional function is specified, the
alarm DS1121 occurs.
3 If Parameter EED (No.6301#3) is set to “1”, the Data area
can be specified by 32bit data specification.
Under the setting, the external tool offset range is up to +/ -
79999999.
