SAFETY PRECAUTIONS
B–63664EN/02
s–6
CAUTION
1. Absolute/incremental mode
If a program created with absolute values is run in incremental mode, or vice versa, the machine
may behave unexpectedly.
2. 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
details.
3. Torque limit skip
Before attempting a torque limit skip, apply the torque limit. If a torque limit skip is specified
without the torque limit actually being applied, a move command will be executed without
performing a skip.
4. Programmable mirror image
Note that programmed operations vary considerably when a programmable mirror image is
enabled.
5. 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.
6. Gap control
Tracing control is performed to keep the gap constant. During tracing control, ensure that the
nozzle does not move to any location other than around the workpiece. Otherwise, the nozzle may
collide with the machine, possibly causing damage to the nozzle and the machine.
