FANUC Series 30i-MODEL A
Input of tool offset value measured B
Tool offset write signal
+MIT1~ +MIT7<Gn132#0~ #7> -MIT1~-MIT7<Gn134#0~#7>
[Classification] Input signal
[Function] Each of these signals inhibits the tool from being fed along the orresponding
axis during manual operation. When signal GOQSM for selecting the mode for writin
g tool compensation is set to “1”, the manual feed is inhibited and also the tool geo
metry compensation along the axis is automaticall calculated and the result is set in
tool compensation memory.
[Operation] When these signals are turned “1”, the control unit operates as follows:
・ Inhibits tools from being fed along the corresponding axis during manual operation.
+MIT1 : Inhibits the tool from being manually fed in the positive direction along the X-axis.
–MIT1 : Inhibits the tool from being manually fed in the negative direction along the X-axis.
+MIT2 : Inhibits the tool from being manually fed in the positive direction along the Z-axis.
–MIT2 : Inhibits the tool from being manually fed in the negative direction along the Z-axis.
If the TS1 parameter (bit 3 of 5004) is 1
+MIT1 : Automatic decision causes the related two directions of each axis to be subjected to
interlock.
–MIT1 : Not used
+MIT2 : Not used
–MIT2 : Not used
・ When signal GOQSM for selecting the mode for writing tool compensation is turne
d “1”, the manual feed interlock signal also automatically calculates the tool geometry
compensation for the tool compensation number pointed to by the cursor and sets th
e result in tool compensation memory.
Note
This signal is valid only when the bit 0 (GSC) of parameter
No. 5009 is 1.
Tool offset number select signals
OFN0~OFN5, OFN6~OFN9<Gn039#0~#5, Gn040#0~#3>
[Classification] Input signal
[Function] Selects the tool offset number.
[Operation] When the mode for writing tool compensation is selected, the cursor is automatically positioned
on the tool geometry compensation number selected by these signals.
A tool offset number is specififed by a 10–bit binary number. Numbers 0 to 998 correspond
to the compensation number 1 to 999.
Note
This signal is available only when parameter QNI No.50
05#5) =1.
