Q:What is the main function of the frequency converter on the machine tools?
Where is the difference between soft starter and converter?
Q:Delta inverter fault output which parameter is set?
1 undervoltage show that the inverter power input part of the problem, you need to check before you can run.  5.2, the temperature is too high, such as motor temperature detection device, check the cooling situation of the motor; inverter temperature is too high, check the frequency converter ventilation.
Q:What are the key points of frequency converter maintenance?
(brief introduction of main circuit of frequency converter)The main circuit of the inverter is composed of four parts: input, rectification, filtering and inverting. The three-phase alternating current is converted into DC through rectification and filtering, and then is converted into three-phase alternating current with arbitrary frequency and voltage. Middle DC link capacitor, due to the large capacitance, DC voltage of the main circuit is relatively stable, the resistance is very small, with the characteristic of the voltage source, a voltage type inverter in the speed control system of asynchronous motor, because the motor is inductive, capacitive reactive power at the same time as a buffer storage component.
Q:At the base block Yaskawa inverter is what reason?
This is the base block command, when the external input block command signal, the frequency converter will appear this code, the emergence of this code, the motor will rotate freely, does not affect the use.
Q:Hello everyone, I was doing fine tuning, ask inverter carved machine always ranging from the time jump out ah?
It should be a frequency converter. Right now, look at the frequency converter output frequency settings, tune, and suggest the next election wide output frequency converter, or simply PLC
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: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:What is the difference between a converter and a transformer in Yu Na?
The frequency changer changes the frequency of alternating current. The transformer changes the voltage.Take a closer look at the materials on the electrician.
Q:What is the frequency converter through function?
The default power loss time is 5S.Using DSU's high-power inverters, you need to set the time delay in DSU software to activate this function.The power down function is unique across some converter functions. In the power plant, semiconductor, petrochemical and other industries has been widely used to solve the power problem recurring and electricity, the massive economic losses caused momentary loss of power equipment downtime caused by continuous production. To protect the user to the greatest extent.
Q:Does the number of inverter settings differ from the number of motor poles, and does it affect the use?
The influence of the inverter on the motor control model, in addition to the speed difference, basically does not affect much
