WARNINGS AND CAUTIONS RELATED TO
This section covers the major safety precautions related to programming. Before attempting to
perform programming, read the supplied operator’s manual and programming manual carefully
such that you are fully familiar with their contents.
1. Coordinate system setting
If a coordinate system is established incorrectly, the machine may behave unexpectedly as a
result of the program issuing an otherwise valid move command.
Such an unexpected operation may damage the tool, the machine itself, the workpiece, or cause
injury to the user.
2. Positioning by nonlinear interpolation
When performing positioning by nonlinear interpolation (positioning by nonlinear movement
between the start and end points), the tool path must be carefully confirmed before performing
Positioning involves rapid traverse. If the tool collides with the workpiece, it may damage the
tool, the machine itself, the workpiece, or cause injury to the user.
3. Function involving a rotation axis
When programming polar coordinate interpolation or normal–direction (perpendicular) control,
pay careful attention to the speed of the rotation axis. Incorrect programming may result in the
rotation axis speed becoming excessively high, such that centrifugal force causes the chuck to
lose its grip on the workpiece if the latter is not mounted securely.
Such mishap is likely to damage the tool, the machine itself, the workpiece, or cause injury to
4. Inch/metric conversion
Switching between inch and metric inputs does not convert the measurement units of data such
as the workpiece origin offset, parameter, and current position. Before starting the machine,
therefore, determine which measurement units are being used. Attempting to perform an
operation with invalid data specified may damage the tool, the machine itself, the workpiece, or
cause injury to the user.
5. Stroke check
After switching on the power, perform a manual reference position return as required. Stroke
check is not possible before manual reference position return is performed. Note that when stroke
check is disabled, an alarm is not issued even if a stroke limit is exceeded, possibly damaging
the tool, the machine itself, the workpiece, or causing injury to the user.
