1.2 GENERAL WARNINGS AND CAUTIONS
WARNING
1 Before operating the machine, thoroughly check the
entered data. 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.
2 Never attempt to machine a workpiece without first
checking the programmed value, compensation value,
current position, and external signal settings. Also, never
attempt to machine a workpiece without first checking
the operation of the machine. Before starting a
production run, ensure that the machine is operating
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. Failure to confirm the correct
operation of the machine may result in the machine
behaving unexpectedly, possibly causing damage to the
workpiece and/or machine itself, or injury to the user.
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 no need to change them. When,
however, there is no alternative other than to change a
parameter, ensure that you fully 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.
