WARNING
[Function]
If the alarm is displayed when an overheat alarm is detected in the control unit or communication
terminal‚ the overheat signal will be output simultaneously. If the machine is in automatic operation‚
the operation will be continued‚ but restarting will not be possible after resetting or stopping with
M30. (Starting will be possible after block stop or feed hold.)
For details on the operation, etc., refer to "Temperature warning cause (R41)".
CAUTION
If the temperature rise detection function is invalidated with the parameters, the control could be
disabled when the temperature is excessive. This could result in machine damage or personal
injuries due to runaway axis, and could damage the device. Enable the detection function for
normal use.
