FANUC Series 30i-MODEL A
Start lock, Interlock signal
for each axis and direction
NOTE
The overtravel distance of the motor after turning *IT to “0” is
represented by the following formula.
Qmax = Fm×1/60×(A/1000+Tc/1000+Ts/1000)
Qmax : Overtravel quantity[mm or inch]
Fm : Feedrate[mm/minor inch/min]
Tc : Cutting time constant [ms]
Ts : Servo time constant(Ts=33ms normally)
A : Processing time of CNC
A=50ms
When acceleration/deceleration before read-ahead interpolation is used, the
distance required for deceleration using acceleration/deceleration before
interpolation is added to the above formula.
Interlock signal for each axis*IT1 to *IT8<G130>
[Classification] Input signal
[Function] These signals disable feed along axes on an axis-by-axis basis. A
separate interlock signal is provided for each controlled axis. The number
at the end of each signal name denotes the number of the corresponding
controlled axis.
*ITx
x : 1 ..... Interlock for the first axis.
2 ..... Interlock for the second axis
3 ..... Interlock for the third axis

[Operation]
a) In manual operation The movement of an interlocked axis is inhibited, but
the other axes are movable. If an axis is interlocked during movement, it
stops after being decelerated, and it starts moving again when it is released
from interlock.
b) In automatic operation (MEM RMT or MDI mode) If an axis is
interlocked while its movement is being commanded(the move amount is
not 0, inclusive of the tool offset), movement in all axes is prevented. If a
moving axis is interlocked, all axes stop moving after being decelerated,
and they start moving again when interlock is released.
This function is also effective during dry

[Classification] Input signal
[Function] This function allows a directional interlock for each axis.
.
[Operation] When the axis/directional interlock signal becomes “1”, CNC applies
interlock only in the corresponding axial direction. However, during
automatic operation, all axes will stop.
