Q:Which brand of converter is better?: Supporting the use of Sinopec group, double coin group and other national key projects, the quality of product quality and good customer service service won the praise of users!

Q:What is the difference between frequency converter and servo driver?: The difference between servomotor and frequency conversion motor:Servo system is a closed-loop control system, the inverter usually works in open-loop control, so in terms of speed and accuracy, and can not be compared to the servo drive.The frequency conversion is only one part of the servo, and the servo controls the closed loop precisely on the basis of frequency conversion so as to achieve better results.

Q:How does the frequency converter fit the brake unit and the brake resistor?!: The kinetic energy of the motor shaft are much different. The load on the motor shaft, the kinetic energy is different, for example, motor used in cranes, in addition to the kinetic energy, potential energy and objects, should add up to the shaft of the motor, the energy will be consumed in the resistance.

Q:What are the contents of frequency converter maintenance?: Replacement of spare partsThe inverter consists of various components, some parts of the work for a long time after its performance will gradually decrease, aging, which is the main reason of inverter fault, in order to ensure the normal operation of equipment for a long time, the device should be replaced regularly:

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:What are the benefits of installing economizer in industrial enterprises?: The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.

Q:What's the difference between universal inverter and fan pump converter?: In practice, the production machinery is often divided into three types: constant torque load, constant power load and fan, pump load.Constant torque load:The load torque TL is independent of the speed n, and the TL remains constant or almost constant at any speed. For example, conveyor belts, mixers, extruders and other friction loads, as well as cranes, hoists and other potential loads are constant torque load.When the inverter drives the load with constant torque, the torque at low speed is large enough and has enough overload capacity. If it is necessary to operate at a low speed, the cooling capacity of the standard asynchronous motor should be taken into consideration, so as to avoid the excessive temperature rise of the motor.

Q:Frequency converter OC alarm, what's the matter?: The frequency at which the OC fault occurs in all faults of the inverter may be the highest and the most frequent. In the process of starting the alarm, in the process of stopping the alarm, alarm in operation, so that power on the alert, and even with other fault codes or currentIndirectly tell you that there is a OC fault in this inverter!

Q:What does "EPCU" mean in a frequency converter?: This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory

Q:What are the precautions for frequency converter wiring installation?: 1, between the power supply and inverter, access to low-voltage circuit breaker and contactor, protection of frequency converter and easy installation and maintenance;2, frequency converter and motor are generally not allowed to access contactor;3, frequency converter generally does not need to meet the thermal relay;4, the output side of the inverter is not allowed to connect capacitors and capacitive single-phase motors.5, the surrounding pay attention to ventilation, dust-proof6, the power input line has sufficient area, the screws tighten as far as possible, but do not slip, you can refer to the specifications torque.7, connect the motor cable as short as possible, there are computer occasions, as far as possible shielded cable8, the control signal line should not parallel to the power line. If parallel must be used, the shielding line and one end of the earth will be used.9, use 485 or 232 communication to wear a magnetic ring, and use twisted pair.
