Maintenance of Japanese big gold servo drive
Model: Dajin SUT00D12818
Cause of failure: telegraph E16 alarm
Fault analysis: this customer is in the normal use of E16 alarm, according to the Japanese great gold servo principle. The servo pump is driven by a servo motor. The servo oil pump that is to be tried is driven by an AC servo motor. Servo motor belongs to the category of control motor. Its main function is to transfer and transform signals, such as servomotor, converting voltage signal to torque and speed. The main requirements for motor control are sensitive, accurate, reliable operation and less power consumption. According to Dajin servo manual, the trouble code is found. The reason is overvoltage alarm. The static measurement module and detection circuit element are normal. The circuit of voltage detection circuit is found to be damaged by the power check and check voltage detection circuit. After the replacement, the fault remains unchanged, and the power supply voltage is normal on the A7840. According to the following circuit diagram A7840 circuit detection, it is found that the TL084 magnified IC has no voltage change, and the fault is relieved after the replacement.
Jiahong Wei repair Japan Daikin servo drive, no display, lack of phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, display and output, module damage, failure code and so on can be maintained.
