Stainless steel precision castingCNC lathe spindle selection point is not weighing debugging failure.

Failure status: A certain type of FSO exhausted CNC machining center, auxiliary equipment S system software spindle controller, during adjustment, the spindle selection point is unstable and invalid. Analyze and deal with methods; during maintenance, carry out continuous tests based on several precise positionings to determine the specific fault status of the fault; CNC lathes can accurately locate the spindle at any time, with the correct posture; after repositioning, the selected point will be selected every time Different, the main axis can be positioned on any map. Because the whole process of the precise positioning of the spindle is actually at the encoder zero pulse position, the spindle is terminated at the precise positioning, and closed-loop control adjustment is performed at that position. Based on the above conditions, it can be determined that the encoder zero pulse is not fixed and caused by the fault. This analysis is probably due to the following reasons: the upper part is faulty; the encoder is fixed, and the relative position of the encoder and the spindle is constantly changing during the entire rotation; the encoder is good, no; zero pulse; output or; zero pulse ; Affected; the encoder wiring is incorrect.Stainless steel precision castingAccording to the above possible reasons, check one by one to eliminate the reasons of poorly fixed encoder and poorly fixed encoder. Further check the wiring of the encoder and found that the ground wire of the zero pulse transformer in the encoder was connected wrongly. After re-wiring, the fault was rectified.
