Q: What is the difference between a frequency converter and a servo controller?: The speed of an asynchronous motor is =60f/p.f, the frequency of alternating current, P is the pole, and the logarithm.60 is the number of seconds in a minute. As can be seen from the form, the number of poles has been fixed. The speed of the asynchronous motor is proportional to the frequency of the power supply. The frequency of the asynchronous motor is changed by changing the frequency of the power supply. This is the principle of variable frequency speed regulation

Q: How does the frequency converter fit the brake unit and the brake resistor?!: To calculate how much energy consumption, can be converted into electric current, to select the brake unit. You can also choose the braking resistance (to consider resistance temperature characteristics to choose), then select the brake unit with matching (see manufacturer manual).

Q: When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: However, when the frequency is raised, the current will decrease if the load is not large, especially when the motor is idle. The magnitude of the current is determined by the load. If you can add some load, you will see the current rise. Speaking of principles, can be understood as the motor is a big inductance, when the power frequency increases, the motor impedance Z will become larger, the impedance is large, the voltage is constant, the flow of the current will naturally be small,

Q: Can the frequency converter 7.5KW take the motor with 11KW?: No, in general, the selection of frequency converter is larger than that of motor, that is 11W frequency converter with 7.5KW motor.A motor with variable torque with a constant torque converter, which is permissible. But the load and the motor are constant torque, and the frequency converter is also constant torque, so doing is the small horse cart. Because the actual click can work continuously load is only 5.5kW, and then big, frequency converter can not stand.

Q: What is the function of a frequency converter on an electric motor?: Through the frequency converter, the motor can be adjusted speed, so as to obtain the speed required by itself, and also can reduce the motor running current and save energy and reduce consumption.

Q: Today, I was asked the question, and I also brought it to you to share the following Oh!: The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.

Q: What does Ro1c mean on a converter?: Relay output converter dry contact signal, RO1C is the common end and RO1A is closed, RO1B is normally open, this set of contacts is prepared to run the factory setting output signal, power on self-test is completed can run the relay output signal. It can be modified to the output point of the signal such as fault and operation in the twenty-fourth set of parameters.

Q: How to deal with the fault Yaskawa inverter GF: Inverter display "GF" fault information for ground fault (i.e. the output current exceeds the rated current of the inverter 50%), a power module is reported for G5 damage, may also be a driving circuit, running the report "GF" (the external load is a good case), G5 is PC929 damage. With current detection circuit,

Q: Can 220V use frequency converter to drive three-phase motor with 380V?: Can not. The inverter (frequency transformer) is the use of power semiconductor devices will be the role of on-off frequency to another frequency power conversion power control device, can not boost, out of the single-phase 220V AC inlet is three-phase 220V AC frequency converter.

Q: Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?: Inverter is to realize the speed adjustment of AC asynchronous motor by changing the motor power supply frequency, speed adjustment and balance, load property of the motor does not change with changes in speed, suitable for load adjustment and torque adjustment. Good performance, but high cost.
