Q:What is the difference between SIEMENS inverter and built-in filter?
There is no built-in filter converter in the price slightly lower, mainly used in the equipment efficiency (power factor) requirements are not high, anti-interference ability requirements are not strict place;The frequency difference with built-in filter is mainly to the requirements of different electrical parameters in specially designed, can improve equipment (power factor), has the good anti-interference ability, prevent the transient surge of inverter module impact, has a good protective effect.
Q:What are the parameters of the frequency converter? Thank you
Inverter function parameters are many, generally have ten, or even hundreds of parameters for users to choose. In practical applications, it is not necessary to set and debug each parameter, most of which can only be used as factory settings. But some parameters have great relationship with the actual use, and some are related to each other, so they should be set and debugged according to the actual situation.Because of the type of converter function are different, but the same function parameter name is not consistent, but the type of converter is almost always some basic parameters, can be done completely by analogy. The following parameters are basically used:
Q:There is much dust and moisture in my workshop. Many brands are not durable.
You can't do anything like this! Dust will fall on the circuit board and cause short circuit of the component. The same humidity.Suggest to strengthen the protection level of cabinet. But heat must be taken into account. Or make an independent electrical room. Install air-conditioning. As God offered!
Q:What are the basis of the frequency converter to choose?
1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor
Q:What does a frequency converter do?
What is the starting current and starting torque of the motor when the inverter is in operation?Using frequency converter operation, with the acceleration of the motor, accordingly improve the frequency and voltage, the starting current is limited to 150% rated current (according to the type of machine is 125%~200%). The starting current is 6~7 times of direct starting with the mains frequency power supply, so the mechanical and electrical impact will be produced. It can start smoothly with frequency converter (longer starting time). The starting current is 1.2~1.5 times the rated current, the starting torque is 70%~120%, the rated torque; for the inverter with automatic torque enhancement, the starting torque is above 100%, and the full load can start.
Q:The difference between soft starter and converter
The soft starter is during the start-up of the equipment to take blood pressure or other ways to reduce the starting current of the inverter machine, the device is in operation according to the equipment load by changing the size of the power frequency and regulating equipment output.
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:First of all, I would like to achieve the frequency converter with motor static linear acceleration, high-speed linear deceleration stop processFirst question: I say kind of situation, three paragraph speed start, 0.1hz---> high 30hz-->0.1hzSecond problem: manual speed instruction 1, speed 2, speed 3 instruction instruction I want to use PLC to control three speed motor with three reverse contact dry. I understand speed instruction 1 is switched on (2, 3 connected) transmission section set the frequency with the frequency segment set 0HZ123 AssociationThird questions: manual section, speed command, main frequency and STEP1-STEP7 stage setting frequency, I use PLC analog to the frequency main frequency setting, plus and deceleration, STEP1-7 are set 0, can achieve what I wantInitial contact frequency converter, home pointing
Control the three section speed inversion section, the speed instruction setting surface needs three frequency (M series frequency converter P-17, P-18, P-19) beforehand, which frequency conduction section fast contact line is needed
Q:Surface grinder can add frequency converter, what are the advantages and disadvantages?
SAJ inverter in the industry's specific applicationZhejiang Kanmen machine tool factory mainly produces all kinds of economic type simple NC machine, due to the higher failure rate of electromagnetic clutch speed regulation, realize VVVF system has more advantages, so using VVVF inverter to achieve the three. The details are as follows:
Q:Why does the frequency change when the frequency converter regulates the frequency?
That's for sure. The curve of voltage and frequency should be set according to the load condition, but after the rated frequency of the motor, the voltage is kept at the rated voltage
