Daikin servo driver maintenance
Model: Daikin SUT00D12818
Fault reason: on cable E16 alarm
Fault analysis: the customer is E16 alarm in normal use, according to the working principle of servo daikin. Servo pump is driven by the servo motor, the upcoming test of the servo pump is driven by AC servo motor. Servo motor control motor belongs to the category, its main function is to transfer and conversion signal, such as servo motor converts voltage signals to the torque and rotational speed, main requirements for motor control: action sensitive and accurate and reliable operation, low power consumption etc.. According to the instructions to find the fault reason Daikin servo code for over voltage alarm, static measurement module and a detection circuit element, power check voltage detection circuit A7840 detected the damage of components, after the replacement of the fault still, in the power supply voltage is normal test. According to the following circuit diagram A7840 circuit detection found TL084 amplifier IC no voltage change, after the replacement of the failure to remove.
Hong Jia Wei Daikin servo drive without maintenance display, lack of phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, display output, module damage, fault code can repair report.
