GENERAL WARNINGS AND CAUTIONS
WARNING
1. 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.
2. 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.
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.
6. Immediately after switching on the power, do not touch any of the keys on the MDI panel until the
position display or alarm screen appears on the CNC unit.
Some of the keys on the MDI panel are dedicated to maintenance or other special operations.
Pressing any of these keys may place the CNC unit in other than its normal state. Starting the
machine in this state may cause it to behave unexpectedly.
7. The operator’s manual and programming manual supplied with a CNC unit provide an overall
description of the machine’s functions, including any optional functions. Note that the optional
functions will vary from one machine model to another. Therefore, some functions described in the
manuals may not actually be available for a particular model. Check the specification of the
machine if in doubt.
