Converter is the use of power semiconductor devices will be the role of on-off frequency power conversion to another frequency power control device can realize the AC asynchronous motor soft start and frequency conversion, improve operation accuracy, change the power factor, current / voltage / overload protection function. The utility model is mainly used in the application of the fan and the water pump. In order to ensure the reliability of production, all kinds of production machinery in the design with power drive, there is a certain amount of surplus. When the motor can not run under full load, in addition to achieve the power driven requirements, the excess torque increases the active power consumption, resulting in the waste of electricity. Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water supply, its high input power, and a large amount of energy consumption in the process of the baffle and valve closure. When using variable frequency speed regulation, if the flow rate is reduced, by reducing the speed of the pump or fan can meet the requirements. The following talk about the basic methods of the general inverter debugging. The basic methods and steps of the frequency converter debugging are as follows: first, the no-load test of the inverter is 1. 2, the inverter power input terminal through the leakage protection switch to the power supply. 3, check the display window of the inverter display is normal, if not correct, should be reset, otherwise request return. 4, familiar with the inverter operation keys. The inverter has run in general (RUN) and stop (STOP), programming (PROG), P (DATAPENTER), the data confirm the increased (UP, 3), reduce (DOWN, 6) and other key definitions of different inverter operation keys are basically the same. In addition to some of the inverter as well as monitoring (MONITORPDISPLAY), reset (RESET), inch (JOG), shift (SHIFT) and other functional keys. Two, inverter with motor no-load operation 1, set the power of the motor, pole number, to take into account the converter working current. 2, set the maximum output frequency of the inverter, the fundamental frequency, setting torque characteristics. General inverter are equipped with a number of VPf curves for the user to choose, the user should be used in accordance with the nature of the load to select the appropriate VPf curve. If the fan and pump load, the torque converter to run the code set into a variable torque and torque characteristics. In order to improve the low speed performance of the inverter, so that the output torque of the motor can meet the requirements of the production load start, the starting torque should be adjusted. In the induction motor variable frequency speed regulation system, the torque control is more complex. In low frequency, the effect of resistance and leakage reactance can not be ignored. If the VPf is constant, the flux will be reduced, and the output torque of the motor will be reduced. To do this, the voltage should be compensated in the low frequency to improve the torque. General inverter by the user manually set compensation. 3, will be set to the inverter keyboard operation mode, press the operation button, stop button, observe whether the motor can start, stop. 4, familiar with the operation of the inverter failure protection code, observe the thermal protection relay factory value, observe the overload protection set value, need to be modified. The use of the inverter can be used in accordance with the instructions of the inverter on the electronic thermal relay function settings. When the output current exceeds the allowable current, the over current protection of the inverter will cut off the output of the inverter. Therefore, the maximum threshold of the electronic thermal relay of the frequency converter does not exceed the maximum allowable output current of the inverter. Three, with the test run 1, manual operation of the inverter panel stop button, observe the operation of the motor to stop the process and the frequency converter display window to see if there is abnormal. 2, if the start of P to stop the process of motor inverter over-current protection action, should be re set to accelerate the P deceleration time. The acceleration of the motor in the acceleration and deceleration depends on the acceleration torque. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set the acceleration and deceleration time according to the motor inertia and load, so that the frequency rate of the frequency converter can be coordinated with the motor speed.
