Appendix 6 Explanation of Alarms
MITSUBISHI CNC
IV - 94
Z40 Format mismatch
Details
"#1052 MemVal (No. of common variables shared in part system designation)", formatted at "0", was
set to "1".
Remedy
- Reset "#1052 MemVal (No. of common variables shared in part system designation)" to "0" or format
and restart.
Z51 EEPROM ERROR
Details
The data read from EEPROM does not coincide with the data that has been written into it.
Remedy
- If the same alarm occurs with the same operation, a hardware fault may be the cause. Contact the
service center.
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]
(For all models)
0001: The temperature in the control unit is high.
(For M700VS only)
0004: The temperature in the control unit is high.
0005: The temperature in the control unit 2 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 "#6449/bit7 Control unit
temperature alarm ON" to "0". Then the alarm will be invalidated.
Remedy
- Cooling measures are required.
- Turn OFF the controller power, or lower the temperature with a cooler, etc.
