How does Delta inverter adjust the frequency?

Delta frequency converter, frequency adjustment is mainly operated in the control panel, process:

1. Press the Menu button to enter the parameter programming menu.

2, P0.01=1, input this parameter to complete the panel button correction frequency,;

3, P0.01=0, input this parameter can complete the panel to imitate the potentiometer correction frequency;

4. After correcting parameters, press ENTER button to acknowledge, and then press MENU button to exit to 0.00 frequency display condition.

5, use the panel button to correct the frequency, press the upward triangle button to increase the frequency.

** Low operating frequency: that is, the minimum speed of the motor operation. When the motor works at a low speed, its heat dissipation function is very poor. If the motor works at a low speed for a long time, the motor will be burned. And at low speeds, the current in the cable will increase, which will also lead to cable heating.

** High operating frequency: general frequency converter ** high frequency to 60Hz, and some even to 400 Hz, high frequency will make the motor high-speed operation, which for general motors, the bearing can not exceed the external speed operation for a long time, whether the rotor of the motor can accept such centrifugal force.

Carrier frequency: The higher the carrier frequency is set, the greater the weight of the higher harmonics, which is closely related to the length of the cable, motor heating, cable heating, frequency converter heating and other factors.
