Q:What are the parameters of the frequency converter? Thank you: This function is to protect the motor overheating and set up, it is the frequency converter CPU, according to the operation current value and frequency to calculate the temperature rise of the motor, so as to overheat protection. This function is only suitable for "one on one" occasion, and when the "one is more than one", hot relays should be installed on each motor.Electronic thermal protection settings (%) n (A) / motor rated current rated inverter output current (A)] x 100%.

Q:What is frequency conversion? What is the function of frequency converter?: Theoretically, the inverter can be used in all mechanical equipment with electric motor, the motor starts, 5-6 times higher than the rated current, will not only affect the motor service life and consume more power. In the design of the system in the motor selection will leave some margin, the speed of the motor is fixed the same, but in actual use, sometimes running at low or high speed, so the frequency transformation is very necessary. Transducer can realize soft starting and compensating power factor of motor

Q:What's the frequency converter for? What does it look like?: The inverter is mainly used in industrial equipment, such as power plants, water plants, water supply equipment, large pumping station, it is basically a cuboid, a digital display control panel; and in the English show types into the universal type, fan pump type, vector control, different types should be used in different working conditions, voltage grade from 220V-10 million volts, currently has the localization.

Q:How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: You refer to the type and parameters of the frequency changer to select.

Q:A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?: Isolation of interference: the so-called interference isolation is the separation of the source of interference from the susceptible part from the circuit so that they do not generate electrical contact. Usually in the power supply and controller and transmitter amplifier circuit, in the power line using isolation transformer, so as to avoid conduction interference, power isolation transformer can use noise isolation transformer.

Q:I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: No PG vector control (motor with encoder), set the motor parameters self-learning, rated voltage, rated current, fundamental frequency (50, 33.3, 20 HZ motor should pay attention to what kind of), pole number, frequency speed, rated power, the maximum output frequency, etc., set the end after the rotation form self-learning (motor without load), or stop shape self-learning. Even the self-learning control model parameter to the external terminal control, analog voltage is changed to external control, can be CNC, PLC or PC to control its operation.

Q:The difference between soft starter and converter: Soft start only in low voltage system, so called, high voltage motor is currently using more liquid resistance starter (cabinet), commonly known as "water resistance."". The function is almost the same, but the principle is different. The former is activated by thyristor controlled current limiting, and the latter is started by resistance voltage regulation and current limit.

Q:If you don't plug in the PG card, do you use PLC's PID control?Plug in the PG card and the PLC PID control, which is reliable and precise?: There are several kinds of closed loop, speed closed loop, temperature / pressure / flow closed loop.Since you're talking about PG cards, then obviously you have to control speed.Generally speaking, the control precision is related to the hardware, and the PLC can also output pulses.If you are small system, simple control, it is recommended that you use PG card + encoder to save the cost, you can inverter internal PID, and control accuracy is also ok.My feeling, as if the speed control precision is high, is PG card.

Q:Frequency converter, fault, contact action: The frequency converter has 1-2 relay outputs, that is, digital output. By default, most of the output of the fault is the relay. The general definition of the 2 relays is defined as a running output and a fault output.This contact output and inverter circuit inside the electrical isolation, can use 24V, you can use 220V, you can use any lower than the voltage level of 500V to use this contact, according to the actual needs of love then why.

Q:Ask, what is the ratio of frequency converter?: Connect the air switch, the power supply, check the wiring is correct, close the air switch, turn on the frequency converter, and the digital tube shows 0.Turn off the power, the power indicator light is extinguished, then connect the motor, on-off switch, tone potentiometer, trimmer potentiometer, inching button, frequency meter (0 ~ 10V voltage meter), three sets of inverter and motor proportion of joint operation, the inverter and the motor grounding terminal reliable grounding, and carefully check.
