Warning and caution on DNC operation
WARNING
1 When performing DNC operation, check the NC
program. If an incorrect NC program is used, the
machine and tool can perform an unexpected
operation, thus damaging the workpiece and
machine, and causing human injury.
2 When performing DNC operation, do not start
machine immediately. By using functions such as
the single block, feedrate override, and machine
lock functions, check that the machine and tool
controlled by DNC operation operate safely.
If operation is performed using incorrect data, the
machine can perform an unexpected operation,
thus damaging the workpiece and machine, and
causing human injury.
CAUTION
DNC operation may temporarily stop, depending on
the capability of the personal computer, the number
of NCs connected, and the size of the
communication buffer on the NC side. Moreover,
DNC operation may temporarily stop when software
irrelevant to NC program transfer such as software
for personal computer screen operation is
executed. In these cases, reduce the number of
machines on which DNC operation is performed
simultaneously.
Exclusive file control
NOTE
Be careful not to perform multiple operations such
as download, upload, edit, copy, move, and delete
operations simultaneously for the same NC
program.
