How to set the running settings of the inverter

There are many setting parameters of Delta inverter, and each parameter has a certain range of choice. In use, it is often encountered that the improper setting of individual parameters causes the Dongguan Delta inverter to not work properly.

Control mode: speed control, torque control, PID control or other means. After taking the control method, it is generally necessary to perform static or dynamic identification according to the control accuracy.

Very low running frequency: the minimum running speed of the motor. When the motor runs at low speed, its heat dissipation performance is very poor. When the motor runs at low speed for a long time, the motor will burn out. At low speeds, the current in the cable also increases, which can also cause the cable to heat up.

Very high operating frequency: the general Delta inverter has a large frequency to 60Hz, and some even reach 400Hz. The high frequency will make the motor run at high speed. For ordinary motors, the bearings cannot run for a long time at super rated speed. Whether the rotor can withstand such centrifugal force.

Carrier frequency: The higher the carrier frequency setting, the higher the higher harmonic component, which is closely related to the length of the cable, the heating of the motor, and the heating of the cable heating inverter.

Motor parameters: Delta inverter Set the power, current, voltage, speed, and frequency of the motor in the parameters. These parameters can be directly obtained from the motor nameplate.

Frequency hopping: At a certain frequency point, resonance may occur, especially when the whole device is relatively high; when controlling the compressor, avoid the surge point of the compressor.

In summary, how to set up the running data of Delta inverter, if you want to know more Delta inverter, you can leave a message.
