What are the electrical faults in the CNC woodworking lathe?
High speed stepper motor lost stepIt is possible that the driving power supply voltage is reduced, so that the output torque of the stepping motor is reduced. Should focus on inspection of the drive power part, when the high voltage switch transistor damage, the high voltage power supply approach, high-speed stepper motor output torque reduction and lost step. It may be somewhere in mechanical failure, so we should also check the screw, nut, slide board, stepper motor reducer, when bending, deformation, component or a foreign body will make the running resistance increases, low speed is not obvious, but it cannot completely overcome the high speed running resistance.
Running back stepping motor does not turn jitterThis phenomenon is usually caused by the phase failure of the stepper motor or its control system. It is possible that the stepper motor itself is defective, or it may be a fault in its drive circuit. First check that the connecting plug of the stepper motor is in good contact. If the contact is good, the motor without fault will be replaced to verify that the motor is good. If the replacement of the motor still can not work properly, it shows that the control part is not normal, you can focus on inspection of the drive board on the high power triode and its protective element to release the diode, in general, these two components
The workbench stopped suddenly during the program operationThis phenomenon is usually caused by mechanical failure, but it may be caused by the failure of the control system. At this time, you can return the workbench to the origin and restart the processing program. If the work station is always running to a certain position, it should be a part of the transmission system damaged, deformed or stuck by a foreign object. First off, then check the nut and screw clearance or slide strip is too tight, the ball ball screw guide groove, there is no foreign body, there is no screw bending deformation, stepper motor reducer flexible gear is loose or foreign bodies stuck, if manual turning without exception, is the fault of control system, should be carried out according to the fault check 1.
