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, helical interpolation, or a canned cycle,
the machine may behave unexpectedly. Refer to the descriptions of the respective functions for
9. Programmable mirror image
Note that programmed operations vary considerably when a programmable mirror image is
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
