Breakdown of FANUC 0i system calls the police information (below)

3) undertakes detecting, inside the range that permits in the machine tool when pressure when (0.

4-0.

6MPa) , the contact of pressure switch closes, condition is " Value="1" HasSpace="False" Negative="False" NumberType="1" TCSC="0" W:sT="on">1 " ; When pressure under 0.

When 4MPa, the contact of pressure switch disconnects, condition is " 0 " , after this condition input undertakes deciding logically handling in PMC, think to cannot satisfy a machine tool to move normally, report a mistake in screen code and call the police information. So far, can press the breakdown restoration button on next machine tool face plate, carry out intermediate program to start next, proceed treatment, be opposite at any time the compression that enters a machine tool air pressure undertakes check and be adjustmented, prevent similar breakdown to happen again. 2) system calls the police, 351, 350, 414, 749 call the police machining center of a horizontal, in the course that runs treatment automatically, balk movement, entered park position urgently. Of barrier of the following hereat decide and eliminate a process. Appear at a draught of so much call the police, get the person really muddleheaded, change below numerous for brief, ground of one by one tries to explain and explain. 350, 351, 414, 749 call the police belong to a system to call the police, FANUC wrote relevant maintenance manual correspondingly for numerical control system. Accordingly, can consult BEIJING-FANUC 0i-A maintains a manual (number is B Value="63505" HasSpace="False" Negative="True" NumberType="1" TCSC="0" W:sT="on">-63505C/O1) master those who call the police define and countermeasure. The content that according to calling the police information screen shows, contrast BEIJING-FANUC 0i-A maintains a manual: 1) information: 350 SPC alarm signal: Alarm signal of X axis PLUSE CODER350 SPC: Content of Y axis PLUSE CODER: This is serial pulse coder (of SPC) call the police. The breakdown of serial pulse coder of X Y axis. The following reason can cause this to call the police, the hardware of serial coder appears the unusual, tension that is used at carrying battery of absolutely position coordinate crosses low, feedback cable to appear the contact of the electromagnetism contactor of amplifier of unusual, servo dissolves electric current of servo of the number when unusual, A/D is changed adhesion. 2) alarm signal of information 351 SPC: Alarm signal of 351 SPC of X axis traffic: Alarm signal of 351 SPC of Y axis traffic: Alarm signal of 351 SPC of Z axis traffic: Content of B axis traffic: This also is serial pulse coder (of SPC) call the police. The communication of serial pulse coder of axis of X Y Z B is wrong. The following reason can cause this to call the police, the communication of serial pulse coder unusual, communication has without respondent, deferent data by accident, set of parameter of digital servo side is incorrect. 3) information: Content of 749 S-SPINDLE LSI ERROR: This is about serial main shaft call the police. After receiving electrify source, start in the system medium or in running a course, when main shaft produced serial communication mistake call the police. The following reason can cause this to call the police: Cable contact is undesirable, fall off or break a string, advocate CPU board is undesirable, printed circuit of main shaft amplifier board undesirable. According to above call the police information and call the police content analysis, it is serial pulse coder (the communication respect of SPC) and serial main shaft appeared at the same time problem, such looking also too coincidence? A bit unlikely, the serial pulse coder of 4 servo axis and module of servo of serial main shaft appeared at the same time breakdown. Then, open control report ark to examine numerical control system the circumstance of each module, the power source module that discovers numerical control system, main shaft module, servo axis module does not have power source directive. Be the tripping operation of an air switch that controls them so. So far, bring about this second call the police because place of tripping operation of this air switch is caused,the account that produce is, accordingly, want to remove this trouble, be about to find out the reason of air switch tripping operation. Again detailed ground studied circuit pursues, if plan institute is shown. In the graph, can see, part of servo model block control and electromotor of main shaft cooling fan make overload, short circuit protect this air switch. Whether does the electric return circuit after use avometer checks air switch have the breakdown of overload, short circuit to exist, the electrical wiring that the examination discovers to electromotor of main shaft cooling fan has one look is right ground short circuit, check electromotor of main shaft cooling fan to whether have a problem to the join electrical wiring between electric ark seriously, a termination that discovers jacket is in charge of at this moment becomes loose, and this termination wears away the insulation layer of electrical wiring, machining the concussion that the sudden shift of each servo axis in the process brings, make the fixed termination that protects bushing each becomes loose slowly, caused the happening of this second breakdown. Then, to electrical wiring insulation tatty place did insulation processing afresh, reliable ground has originallied closely to protect the termination of bushing, the fixed termination that is in charge of to other jacket and among them electrical wiring undertook checking, join this examination in the regular examination watch of equipment, put an end to those who be the same as type breakdown to happen again thoroughly. After making above handle, after undertaking trying moving do not have a problem, threw treatment production afresh, so far, trouble removal. Sum up this second breakdown, although what show on screen of alarm signal information is a system,call the police, the first sense that gives a person is occurrence issue of numerical control system, but either it is absolutely such, this breakdown is an exception, this is breakdown of a periphery essentially. Accordingly, when undertaking breakdown decides, the problem that should appear to the likelihood makes the consideration of an overall, eliminate the false and retain the true, ability raises the maintenance level of oneself truly.
