Example)
(1) Spindle collision during automatic operation
If the operation mode is automatic operation such as MEM when the trouble occurs, the operator
states can be clarified by checking the saved following data.
-
The program name and its block number.
-
The machine position and the absolute position.
-
The Modal.
(2) Spindle collision during manual operation
If the operation mode is manual operation such as JOG mode when trouble is occurs, the operator
states can be clarified by checking the saved following data.
-
The machine position and the absolute position.
-
The operation history that the CNC parameter is changed.
19.1.4.1
Restriction of saving
To save CNC information for eight or more days, so number of saving information each day is restricted.
Potential Saving Number
Potential Saving Number means the number of limits that can be preserved in a day.
Potential Saving Number is given basically 10 times a day, but remained Potential Saving Number is
carried over next day. (Maximum 30)
CNC information is remained eight or more days in CNC memory. (Refer to Example.1 to 3)
Potential Saving Number is displayed on diagnosis data No. 4500.
If number of histories that can be saved per day are exceeded, the history at that time will not be saved
even if the machine state history saving condition is satisfied.
The number of history records that were not saved will be recorded in the history that will be saved next
time as the number of unsaved histories.
Non-Save Number
Non-Save Number is the number that CNC information was not saved because of restriction of saving
even if save request condition is fulfilled(signal MSUREQ<G0534.6> changing into “1”, detecting
unexpected abnormal torque, spindle alarm or servo alarm)
Non-Save Number is included in CNC information that will be saved next time.
The maximum value of Non-Save Number is 65535.
Non-Save Number is displayed on Machine state history screen. (Refer to the below figure.)
If “*” displayed at the right of detect time, it means the value of Non-Save Number is 1 or more.
If Non-Save Number is 0, “*” is not displayed.
In details, refer to 22.1.8 Machine state history screen.
