Additional information
If the error cannot be corrected in the "Channel aborted" state, an
appropriate message is displayed when the "Compensation block"
softkey is pressed.
In this case, program execution must be aborted with "NC Reset". The
part program can then be edited under Programming.
4.6.8 Setting the block search/search target
Function
Block search offers the possibility of starting part program execution
from almost any part program block. This involves the NC rapidly
performing an internal run through the part program (without
traversing motions) to the selected target block.
Here, every effort is made to achieve to the exact same control status
as would result at the target block during normal part program
execution (e.g., with respect to axis positions, spindle speeds, loaded
tools, NC/PLC interface signals, variable values) in order to be able to
resume automatic part program execution from the target block with
minimum manual intervention.
