4.5 MANUAL HANDLE INTERRUPTION
By rotating the manual pulse generator in the automatic operation
mode (manual data input, DNC operation, or memory operation) or in
the memory editing mode, handle feed can be superimposed on
movement by automatic operation. A handle interruption axis is
selected using the manual handle interruption axis selection signal.
The minimum unit of travel distance per scale division is the least
input increment. One of four types of magnifiers selected with MP1
and MP2 <G019#4 and #5> can be applied. With bit 3 (HIT) of
parameter No. 7103, the minimum unit of travel distance can be
further 10 times greater. A handle feed magnifier is selected using
the manual handle feed amount selection signal. (See "MANUAL
HANDLE FEED".)

WARNING
The travel distance per scale division by manual
handle interruption is the least input increment as
with manual handle feed. With a machine of metric
input and inch output, for example, the travel
distance per 254 scale divisions is 0.01 inch. With a
machine of inch input and metric output, the travel
distance per 100 scale divisions is 0.254 mm.
