Fig. 4.6 (a) Manual Handle Interruption
D 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
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
The move amount per scale at x1 magnification is 0.001 mm
(metric output) or 0.0001 inch (inch output).
Handle interruption is disabled when the machine is locked
during automatic operation.
