1, initialization reset method: In general, due to transient failure caused by the system alarm, available hardware reset or switch the system power supply in turn to clear the fault, if the system work storage area due to power failure, unplug the circuit board or battery undervoltage caused by confusion, the system must be initialized and cleared, cleared before attention should be paid to make a good copy of data records, if the initialization of the fault still can not be eliminated, the

then carry out hardware diagnosis, then carry out hardware diagnosis.

2, parameter change, program correction method: CNC lathe system parameters are the basis for determining the system function, and the wrong parameter setting may cause system failure or invalidation of a function. Sometimes the user program error can also cause fault stoppage, for which the block search function of the system can be used to check and correct all errors to ensure its normal operation.

3、Adjustment, optimization adjustment method: Adjustment is a simple and easy way. Through the adjustment of the potentiometer, correct the system failure. Such as in a factory maintenance, its system monitor screen confusion, after adjustment is normal. Such as in a factory, its spindle in the start and brake belt slippage, the reason is its spindle load torque is large, and the drive device ramp up time is set too small, after adjustment is normal.

4, spare parts replacement method: replace the bad circuit board diagnosed with good spare parts and do the corresponding initialization to start, the CNC lathe is quickly put into normal operation, and then the bad board is repaired or repaired.
