1.2 GENERAL WARNINGS AND NOTES
WARNING
1 Before operating the machine, thoroughly check the
entered data. Operating the machine with incorrect
data may result in the machine behaving
unexpectedly, possibly causing damage to the
workpiece and/or machine itself, or injury to the user.
2 Never attempt to perform a production run, such as
actually machining a workpiece, without first
checking the operation of the machine. Before
starting the machine for a production run, ensure that
the program command values, offsets, current
position, external signals, and other settings are
suitable for the operation to be performed. Also
check that the machine operates correctly by
performing a trial run using, for example, the single
block, feedrate override, or machine lock function or
by operating the machine with neither a tool nor
workpiece mounted.
3 Ensure that the specified feedrate is appropriate for
the intended operation. Generally, for each machine,
there is a maximum allowable feedrate.
The appropriate feedrate varies with the intended
operation. Refer to the manual provided with the
machine to determine the maximum allowable
feedrate. If a machine is run at other than the correct
speed, it may behave unexpectedly, possibly
causing damage to the workpiece and/or machine
itself, or injury to the user.
4 When using a tool compensation function,
thoroughly check the direction and amount of
compensation. Operating the machine with
incorrectly specified data may result in the machine
behaving unexpectedly, possibly causing damage to
the workpiece and/or machine itself, or injury to the
user.
5 The parameters for the CNC and PMC are factory-
set. Usually, there is not need to change them.
When, however, there is not alternative other than to
change a parameter, ensure that you fully
understand the function of the parameter before
making any change. Failure to set a parameter
correctly may result in the machine behaving
unexpectedly, possibly causing damage to the
workpiece and/or machine itself, or injury to the user.
