10.TOOL FUNCTION B-63323EN-1/03
- 1022 -
NOTE
This operation requires a reader/punch interface
and a programmable data input function.
(5) Input from external equipment
When the read soft key is selected on the fixture offset screen,
data can be input from external equipment such as a Floppy
Cassette via the RS-232C interface.
Data is input in G10 format without a program number.
NOTE
This operation requires the use of a reader/punch
interface and a programmable data input function.
- Calculating a fixture offset
(1) Relationship between rotation axes and linear axes
First group: 4 (B-axis), 3 (Z-axis), 1 (X-axis)
Second group: 5 (C-axis), 1 (X-axis), 2 (Y-axis)
Third group: 0, 0, 0
(2) Reference angle and reference fixture offset

Limitation
- If data is changed in G54.2 mode
If a parameter setting or reference fixture offset is changed in G54.2
mode, the new data is valid from the next block to be buffered.
