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.
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.
