SAFETY PRECAUTIONS
s–6
WARNING
5. Constant surface speed control
When an axis subject to constant surface speed control
approaches the origin of the workpiece coordinate
system, the spindle speed may become excessively
high. Therefore, it is necessary to specify a maximum
allowable speed. Specifying the maximum allowable
speed incorrectly may damage the tool, the machine
itself, the workpiece, or cause injury to the user.
6. 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.
7. Absolute/incremental mode
If a program created with absolute values is run in
incremental mode, or vice versa, the machine may
behave unexpectedly.
8. Plane selection
If an incorrect plane is specified for circular interpolation
or a canned cycle, the machine may behave
unexpectedly. Refer to the descriptions of the respective
functions for details.
9. Programmable mirror image
Note that programmed operations vary considerably
when a programmable mirror image is enabled.
10. Compensation function
If a command based on the machine coordinate system
or a reference position return command is issued in
compensation function mode, compensation is
temporarily canceled, resulting in the unexpected
behavior of the machine.
Before issuing any of the above commands, therefore,
always cancel compensation function mode.
