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]
0001: The temperature in the control unit is high.
0002: The temperature around the communication terminal (setting and display unit)
is high.
0003: The temperature in the control unit and around the communication terminal
(setting and display 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.
Remedy
- Cooling measures are required.
- Turn OFF the controller power, or lower the temperature with a cooler, etc.
