Common troubleshooting methods for Siemens servo motor maintenance company: Firstly. The common causes of such faults caused by mechanical oscillation (during acceleration/deceleration) when the motor is powered on are: ① Malfunction of the pulse encoder. At this point, it is necessary to check whether the servo system is stable, whether the circuit board maintenance checks whether the current is stable, and whether the voltage on the feedback line terminal of the speed detection unit drops at certain points. If there is a drop, it indicates that the pulse encoder is faulty and needs to be replaced; ② The cross coupling of the pulse encoder may be damaged, causing the shaft speed to be out of sync with the detected speed. Replace the coupling; ③ The speed generator has malfunctioned. Repair and replace the speedometer. In maintenance practice, there are many faults such as wear and blockage of the speed measuring machine brush. At this time, the speed measuring machine brush should be removed, polished several times with sandpaper, and the dirt on the commutator should be cleaned before reinstalling. Secondly, when the motor is powered on and the mechanical motion is abnormally fast (runaway), if this servo system failure occurs, it should be checked not only for the position control unit and speed control unit, but also for: ① whether the pulse encoder wiring is incorrect; ② Is the coupling of the pulse encoder damaged; ③ Check if the terminals of the speed generator are reversed and if the excitation signal line is connected incorrectly. Generally, such phenomena should be handled by professional circuit board maintenance technicians, otherwise it may cause more serious consequences. Thirdly, in the event of a servo system malfunction where the spindle cannot move in a directional manner or does not move properly, it is necessary to check the settings and adjustments of the directional control circuit, the directional board, and the spindle control printed circuit board. At the same time, the output waveform of the position detector (encoder) should also be checked to determine the quality of the encoder (attention should be paid to recording the normal output waveform of the encoder when the equipment is normal, in order to check for faults). Fourthly, when feeding the coordinate axis, the vibration should be checked by checking the connection between the motor coil, mechanical feed screw and motor, servo system, pulse encoder, coupling, and speedometer. Fifth, the occurrence of NC error alarms is caused by program errors or operational errors in NC alarms. If the Nc of FANUC6ME system shows an alarm of 090.091, the possible reasons may be: ① main circuit failure and low feed rate; ② Poor pulse encoder; ③ The power supply voltage of the pulse encoder is too low (adjust the power supply voltage to 15V at this time, so that the voltage value on the+5V terminal of the main circuit board is within 4.95-5.10V); ④ The reference point return cannot be executed normally without inputting the one revolution signal of the pulse encoder. Sixth. Servo system alarm

Servo system faults often result in the following alarm numbers, such as 416, 426, 436, 446, 456 servo alarms in FANUC6ME system; 1364 servo alarm of STEMEN880 system; The servo alarms of 114, 104, etc. in the STEEMENS8 system should be checked at this time: ① If the feedback signal of the shaft pulse encoder is disconnected, short circuited, or lost, use a crossover device to measure the A and B phase rotation signals to see if they are normal; ② Internal faults in the encoder result in incorrect signal reception. Check for contamination, dirt, deformation, etc. Service process of Siemens servo motor repair company: Step 1: First, inquire about the fault phenomenon and on-site situation of the damaged electrical equipment from the user. Step 2: Analyze the causes of such faults based on the user's fault description. Step 3: Thoroughly clean the machine, identify damaged components, and analyze the feasibility of repair and restoration. Step 4: Based on the location of the damaged component, identify the cause of the damage to avoid similar malfunctions in the future. Step 5: Provide a detailed inspection report and repair quotation, and after Party A confirms the quotation, carry out the repair. Step 6: Conduct a load test on the device after repair, notify Party A of normal operation, and ship upon payment
