Interrupt feeding is a control operation that feeds an axis for a fixed distance,
using speed control until an external signal is input and then switching to posi-
tion control at that point.
Interrupt feeding can be performed either at constant speed or two-stage
speed.
For details on using interrupt feeding with the G language, refer to 7-3-14
G31: INTERRUPT FEEDING.
It is also possible to specify a travel distance at which to stop when there is no
interrupt input. Operation will normally stop with an error (program execution
interrupted) after positioning, but an S option can be used to execute the next
block without an error occurring.
