FANUC 0i system is common have call the police the trouble removal of information

System of FANUC 0i numerical control is had diagnose a function more by force oneself, to a few common breakdown, through calling the police information, correspondence maintains a manual, can solve a lot of problems. A few common newspapers introduce below alarm the processing technique of breakdown. 1, 500 good call the police (exceed the journey to call the police) the journey exceeds to call the police to often appear in eliminating the process that the method handles in numerical control machine tool, as a result of inertial reason, press switch of Cheng of be issued to lower levels when mobile axis when, need decelerate to stop, in the meantime, the system appears 500 call the police, show at the same time call the police the reference axis that information has reached the journey to cross the route. It is to remove below " 500 cross the route: ＋ X " the basic measure that call the police: 1) knob of feed axis choice is dialed " X " axial place; 2) knob of feed fold choice is dialed " × 1 " place; 3) pass on coming back shakes pulse generator makes X axial loses direction to move, leave ultimate position; 4) press on MDI clavier " RESET " key, call the police information disappears. 2, 90 call the police (return reference point position unusual) eliminate a method to call the police condition: Should return error of reference point position too big or CNC did not receive coder of servo electric machinery to turn signal, appear 90 call the police. Remove measure: 1) affirm DGN.

300 medium values (allow positional deviation to measure) be more than 128. Raise feed rate otherwise, change fold. 2) affirm whether electric machinery circumgyrate is more than 1 turn. Be less than 1 turn, explain returned position of rest is too close. Adjust a few further. 3) whether the tension that acknowledges coder is more than 4.

75V (the cover after tearing open next electric machinery, the ＋ that measures coder printed board 5 -- 0V) , if under 4.

75V, change batteries. 4) if not be afore-mentioned problems, it is hardware gave an issue certainly: Change coder. 3, 401 call the police (servo preparation signal calls the police) call the police condition: The preparative signal of servo amplifier (VRDY) did not put through, the signal when perhaps moving closes. Remove measure: 1) whether does PSM control power source put through; 2) stop urgently to whether remove; 3) whether is there terminal plug on final amplifier JX1B outlet; 4) whether does MCC put through, if besides PSM connective MCC, still have exterior MCC ordinal circuit, want to check likewise. 5) whether does the power source of drive MCC put through; 6) whether does breaker put through; 7) whether do PSM or SPM happen call the police. If the strong report circuit all round servo amplifier does not have a problem, change servo amplifier; If above measure is insoluble problem, change main shaft controls card. CNC Milling
