the profit is not high enough to make enterprises more reluctant to invest in R & D, so its product quality, grade can only be worse, and this leads to its lower price. Voltage vector control is based on the INVERTER torque current and stator impedance, automatic correction of voltage-frequency characteristics, to compensate for the stator resistance voltage drop. Generally, the compensation value of small capacity inverter is calculated according to stator impedance and exciting current, while the compensation value of large and medium capacity inverter is calculated according to stator impedance and power factor. These parameters can be manually input settings, can also be set for automatic measurement of the converter. In the field, it is recommended to use frequency converter to measure automatically. Since the temperature rise of the motor has an effect on the stator resistance, the measurement is made at startup. With voltage vector control, the motor can output 150% rated torque at 1Hz. The acceleration time of the converter is the time when the output frequency rises from zero to the working frequency, that is, the time when the motor starts and accelerates to the set speed. It can be calculated from the following formula: TQG GD2NG375 FORMULA: MD is the acceleration torque Me of the motor, me For rated Torque, MJ for load static resistance Torque tqg converted to zero to rated speed ned time. Tqetqe NDNGTQG inverter start-up time should be set,
