9.5 External Data Input/Output Signals
(1) External Data Input/Output Function
(a) External work number search input signal
By specifying any of the following proram numbers externally in BCD, the required
work number can be selected.
Program numbers: 1 to 99999
(b) External tool offset input signal
It is possible to correct the offset data (tool length offset data, tool radius offset data)
by using the external data input signal.
(c) External workpiece coordinate system shift input signal
It is possible to correct the shift amount of workpiece coordinate systems by using
the external data input signal.
By inputting the correction data for the individual axes, the input data is added to the
present shift data of G54 to G59 to obtain the new shift data.
(2) Input Signals Used for External Data Input
(a) External data input signal
The external data input signal is used for the workpiece number input signal, offset
data input signal and workpiece coordinate system shift data input signal.
