st
case: in state G40 interrupting and restarting linear interpolation
The diagram shows the case,
when a linear interpolation in the
plane X, Z is interrupted, a
manual mode is set and manual
operation is used along the two
axes. If after all the automatic
mode is returned and after
switching the BLOCK RETURN
condition on the START
button is pressed or manual
operation is used in one of the
manual modes when the BLOCK
RETURN condition is on,
the control goes to the interruption point of the block.
In the return process all axes take part, even those not programmed in the interrupted
block.
If on an axis the
compensation is modi-
fied, as for example
along axis X on the dia-
gram beside, or a work
zero point offset is
changed it returns to X
position valid on the
interruption point of the
block registering the
new compensation or
offset.
