If the BATTERY LOW warning is output, save the machining programs, tool data and
parameters to an input/output device, and then replace the battery. If the BATTERY
alarm occurs, the machining programs, tool data and parameters may be damaged.
After replacing the battery, reload each data item.
If the axis overruns or makes an abnormal noise, press the EMERGENCY STOP
button immediately, and stop the axis.
When setting the parameter not to check the overheat, the control unit and the
communication terminal may not be controlled because of overheat.
In such case, axis runaway may cause a machine breakage, an accident resulting in
injury or death, or device breakage.
To prevent the serious results, ordinarily set the parameters so that the overheat
check is valid.
