(c) Tool compensation number input signals (OFN0, OFN1, OFN2, OFN3, OFN4, OFN5 (#1, #2))
[Classification]
Input signals
[Function] Selects the tool compensation number.
[Operation] When the mode for writing tool compensation is selected, the cursor is automatically posi-
tioned on the tool geometry compensation number selected by these signals. Instead of us-
ing these signals, a parameter can be set so that the operator can select the tool geometry
compensation number on the CRT.
NOTE When the optional function that provides compensation for 160 groups of tools is provided,
the maximum selectable tool compensation number is between 1 to 63 for the Series 15–T,
and between 1 to 31 for the Series 15–TT.
(d) Signal for selecting the mode for writing the shift distance for the workpiece coordinate system
(WOQSM (#1, #2))
[Classification]
Input signal
[Function] Selects the mode for writing the shift distance for the workpiece coordinate system.
[Operation] When this signal is turned on in a manual operation mode, the mode for writing the shift dis-
tance for the workpiece coordinate system is selected. The control unit then automatically
switches the screen displayed on the CRT to the screen for writing the shift distance for the
workpiece coordinate system and blinks the OFST status display in the bottom of the screen
to notify that the mode has been changed to the mode for writing the shift distance for the
workpiece coordinate system. However, this is not performed when the mode for writing tool
compensation values is selected.
(e) Signal for writing the shift distance for the workpiece coordinate system (WOSET (#1, #2))
[Classification]
Input signal
[Function] Automatically calculates and sets the shift distance for the workpiece coordinate system.
[Operation] When this signal goes high the mode for writing the shift distance for the workpiece coordinate
system, it triggers automatic calculation and setting of the shift distance for the workpiece
coordinate system.
