FANUC Series 30i/ 31i/ 32i
Live Tool Control With Servo Motor
This function allows you to execute spindle rotation commands and
spindle-speed functions such as rigid tapping, with a servo motor.
-Spindle speed control with servo motor
Allows you to perform speed control with rotation commands
(S commands), using a servo motor as a live tool. At the switching
between rotation commands and positioning commands, no reference
position return is necessary.
-Live tool indexing function
There are two types of live tool indexing function, one that executes the
commands in the next block without waiting for the completion of live tool
indexing and the other that executes the next block after waiting for the
completion of live tool indexing.
The type that does not wait for completion allows you to specify commands
for other axes before issuing the next command for the live tool indexing
command axis. It allows you to check to see if live tool indexing has
completed before issuing the next command for the live tool indexing
command axis. By using this function, you can reduce waiting time.
Also, by issuing a live tool indexing command during rotation, you can stop
rotation at a specified position.
-Rigid tapping with servo motor
Allows you to perform rigid tapping with a servo motor as a rotation axis.
