Appendix 2 Explanation of Alarms
MITSUBISHI CNC

Z52 Battery fault 000x
Details
The voltage of the battery in the NC control unit has dropped. (The battery used to save the internal
data.)
0001: Battery warning
0002: Battery detecting circuit error
0003: Battery alarm
(Note)The display of "Z52 battery fault 0001" can be removed by resetting. However, the warning state
will not be cleared until the battery is replaced.
Remedy
- Replace the battery of the NC control unit.
- Check for any disconnection of the battery cable.
- After fixing the battery's fault, check the machining program.
Z53 CNC overheat
Details
The controller or operation board temperature has risen above the designated value.
(Note)Temperature warning
When an overheat alarm is detected, the alarm is displayed and the overheat signal is output
simultaneously. Automatic operation will be continued, while restarting after resetting or
stopping with M02/M30 is not possible. (Restarting after block stop or feed hold is possible.)
The alarm will be cleared and the overheat signal will turn OFF when the temperature drops
below the specified temperature.
Z53 CNC overheat 000x
[000x]
0001: The temperature in the control unit is high.
The ambient temperature must be lowered immediately when a "Z53 CNC overheat" alarm
occurs. However, if the machining needs to be continued, set "0" for the following parameter.
Then the alarm will be invalidated.
PLC Parameter BIT SELECT #6449
bit7 : Control unit overheat detected
---setting values---
0: Detect
1: Not detect
Remedy
- Cooling measures are required.
- Turn OFF the controller power, or lower the temperature with a cooler, etc.
