  • The 16 Most Commonly Used Parameters of Inverters (I)
    Aug 05, 2023
    There are many setting parameters of the inverters, and each parameter has a certain range of choices. During use, it is often encountered that the inverter cannot work normally due to improper setting of individual parameters. Therefore, it is necessary to set the relevant parameters correctly.   Allen-Bradley 22P-D045A103 AB400P 1. Control method: That is, speed control, torque control, PID control or other methods. After adopting the control method, it is generally necessary to carry out static or dynamic identification according to the control accuracy.   2. Minimum operating frequency: That is, the minimum speed at which the motor runs. When the motor runs at a low speed, its heat dissipation performance is very poor. If the motor runs at a low speed for a long time, it will cause the motor to burn out. And at low speed, the current in the cable will also increase, which will also cause the cable to heat up.   3. Maximum operating frequency: The maximum frequency of general inverters is 60Hz, and some even reach 400 Hz. The high frequency will make the motor run at high speed. For ordinary motors, the bearings cannot run at super-rated speed for a long time. Whether the rotor of the motor can withstand such a centrifugal force. CT Emerson SP1405 Inverter 4. Carrier frequency: The higher the carrier frequency is set, the greater the high-order harmonic component, which is closely related to the length of the cable, the heating of the motor, the heating of the cable, and the heating of the inverter.   5. Motor parameters: The inverter sets the power, current, voltage, speed, and maximum frequency of the motor in the parameters, and these parameters can be directly obtained from the motor nameplate. RELIANCE ELECTRIC UAZ3455UAZ3475 Inverter   6. Frequency hopping: At a certain frequency point, resonance may occur, especially when the whole device is relatively high; when controlling the compressor, the surge point of the compressor should be avoided.   7. Acceleration and deceleration time The acceleration time is the time required for the output frequency to rise from 0 to the maximum frequency, and the deceleration time is the time required for the output frequency to drop from the maximum frequency to 0. Usually, the acceleration and deceleration time is determined by the rise and fall of the frequency setting signal. When the motor is accelerating, the rate of increase of the frequency setting must be limited to prevent overcurrent, and when the motor is decelerating, the rate of decrease must be limited to prevent overvoltage. Acceleration time setting requirements: limit the acceleration current below the over-current capacity of the inverter, so as not to cause the inverter to trip due to overcurrent stall; the main points of deceleration time setting are: to prevent the smoothing circuit trip the inverter. The acceleration and deceleration time can be calculated according to the load, but in the debugging, it is often used to set a longer acceleration and deceleration time according to the load and experience, and observe whether there is an over-current or over-voltage alarm by starting and stopping the motor; then gradually increase the acceleration and deceleration setting time. Shorten, based on the principle that no alarm occurs during operation, repeat the operation several times to determine the best acceleration and deceleration time.   Allen-Bradley 25B-D4P0N114 Inverter   8. Torque boost Also called torque compensation, it is a method of increasing the low frequency range f/V to compensate for the torque reduction at low speed caused by the motor stator winding resistance. When it is set to auto, the voltage during acceleration can be automatically increased to compensate the starting torque, so that the motor can accelerate smoothly. If manual compensation is used, according to the load characteristics, especially the starting characteristics of the load, a better curve can be obtained through experiments. For variable torque loads, if the selection is improper, the output voltage at low speed will be too high, which will waste electric energy.   YASKAWA CIPR-GA70B4060ABBA-AAAAAA Inverter        Our team of experienced professionals is dedicated to delivering personalized services that exceed our customers' expectations.
