Fig.4.4 Manual Handle Interruption
Handle interruption axis selection signals
For the handle interruption axis selection signals, refer to the manual
supplied by the machine tool builder.
During automatic operation, handle interruption is enabled for an
axis if the handle interruption axis selection signal for that axis is on.
Handle interruption is performed by turning the handle of the manual
pulse generator.
WARNING
The travel distance by handle interruption is determined
according to the amount by which the manual pulse
generator is turned and the handle feed magnification (x1,
x10, xM, xN). Since this movement is not accelerated or
decelerated, it is very dangerous to use a large
magnification value for handle interruption. The move
amount per scale at x1 magnification is 0.001 mm (metric
output) or 0.0001 inch (inch output).
NOTE
Handle interruption is disabled when the machine is locked
during automatic operation.
The following table indicates the relation between other functions and the
movement by handle interrupt.
