Schedule program start |
When the machine was linked with a robot/loader through the
interface type C and the schedule program operation mode was
selected, the cycle start command was issued. Or else, the
schedule program was started when the machine is linked with
a robot/loader through the interface type C.
[Probable Faulty Locations]
1)With the machine linked with a robot/loader in the schedule
program operation mode, the cycle start command was issued.
2)The schedule program operation was attempted with the
machine
linked with a robot/loader.
[Measures to Take]
1)Select a main program instead of a schedule program.
2)Set off the link switch.

not
same in cycle start
2->After tool change and measurement, main program start was
attempted without check button.
3->Main program start was attempted by external start switch,
when machine was not cycle start position.
4->Main program start was attempted without door sensor.
5->Main program start was attempted by NC starat button,
when machine was not cycle start position.

[Probable Faulty Locations]
Worn or broken tool
[Measures to Take]
1)The alarm state is cleared by resetting the NC.
2)Change the cutting tool.

[Measures to Take]
Data transmission from the CEJ matic is abnormal;make
necessary
adjustments referring to the instruction manual for CEJ matic.

cooling or M-spindle cooling.
[Code]
none->In an oil pressure unit actuating signal output, the 1st
Spindle head oil cooler level error signal (or, 2nd Spindle
head oil cooler level error signal)turned more than 1[s] it
off.
1->In an oil pressure unit actuating signal output, M-spindle
head oil cooler level error signal turned more than 1[s] it
off.
2->Spindle oil cooler level low switch(I.0247) remained OFF
longer than 2[S].
[Probable Faulty Locations]
1)Level error of Spindle head oil cooling unit
I/O check NO.24 INPUT bit 7 iOCL/ (1st Main spindle)
I/O check NO.32 INPUT bit F i2OCL/ (2nd Main spindle)
2)Level error of M-spindle oil cooling unit
I/O check NO.34 INPUT bit 9 iMOCLAL/

Both upper limit float switch and lower limit float switch
signals are OFF or coolant alarm signal is OFF.
mounted types> The centrifugal separator alarm (contact B) input signal turned OFF. The clogged thickener separator signal turned ON. [Code] 1->In the cace of concentrated coolant specification, both upper limit float switch and lower limit float switch signals are OFF. 2->In the cace of concentrated coolant specification, coolant alarm signal is OFF. 3->The centrifugal separator alarm input signal turned OFF. 4->The clogged thickener separator signal turned ON. 5->The centralized coolant unit was faulty or saving energy when a coolant supply command was issued or coolant was being supplied (for centralized coolant types). 6->High-pressure coolant unit warning (B-type contact) input signal is OFF in high-pressure coolant system, which is made by chip blaster. 7->In the case of concentrated coolant specification, coolant pressure 1 signal is OFF. 8->In the case of concentrated coolant specification, coolant pressure 2 signal is OFF. 9->The coolant level of the high pressure coolant unit is low. 10->The filter of the high pressure coolant unit is clogged. 11->The pump illegal when high-pressure coolant supply. 12->In the case of concentrated coolant specification,the pressure of coolant is low. 3730 Coolant flow Coolant flow was suspended longer than the monitor time. [Code] None->The coolant flow sensor did not turn ON within the coolant flow monitor time(for coolant supply sensor types). 1->When a flow of coolant1 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant1 or 2nd coolant1 did not flow. 2->When a flow of coolant2 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant2 or 2nd coolant2 did not flow. 3->When a flow of coolant3 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant3 or 2nd coolant3 did not flow. 4->Coolant flow 4 did not flow beyond fixed time at the time of coolant 4 output ON.

[Object] None [Code] XXXXXXXX:The limit switch status for each component of the ATC upon the occurrence of alarm [Probable Faulty Locations] Failure of a limit or proximity switch for ATC sequence check, a cut wire in the input signal circuit, failure of a hydraulic or air solenoid switch for ATC operation, a cut wire in the solenoid operation signal circuit, or faulty hydraulic or air circuit. The faulty ATC sequence limit switch is indicated on the 'ATC CONDITION' screen in AUTO, MDI, and MANUAL OPERATION mode when this alarm occurs due to machine interference. Find the faulty switch and take corrective action.
