Q:How can I control the frequency converter with a computer?: Variable frequency speed control has been applied in the industrial field as the main means of AC motor speed control is very extensive, it has a wide speed range, steady speed and high precision fast dynamic response for a wide range of technical performance and reliable operation, has gradually replaced the DC motor speed control system. There are three main control modes of inverter: 1. through inverter panel operation, that is through the operation panel to change the output frequency and other operating parameters; 2. in the frequency converter analog input 0 ~ 10V or 4 ~ 20mA signal, by changing the size of input analog control of inverter output frequency converter; 3. through communication port (for RS485 control). The first method is generally used for manual adjustment and parameter setting on the spot, and the latter two are mostly used for automatic adjustment and remote control.

Q:What does the RUN key on the inverter mean? How do you use it?: According to the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are many inverter protection functions, such as over-current, overvoltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q:Can the motor with frequency converter directly wave the insulation?: Is not possible because of the use of the insulating shake shake table while the output is DC but after conversion voltage value will exceed the rated voltage of the motor, the only way to test the motor winding phase to ground and insulation. But if the use of motor inverter drive, measurement of motor and inverter will not disconnect it, shake table issued a "high voltage" will be through the introduction of inverter winding inside, will lead to some components breakdown within the inverter a damaged, because although some internal components can be through the large current but the degree of pressure will be very limited so, in the insulating shake measure motor using frequency converter to the inverter and the motor is disconnected after, can make sure not to damage the transducer.

Q:Schneider 303 4KW frequency converter F 013 trouble shooting method: According to the ATV303 user manual,The F013 is a motor overload fault and is triggered by excessive motor current.Suggest:1. monitor the running condition of the converter with the panel (whether the actual running current exceeds the limit)2. check the motor thermal protection settings and motor load (such as motor drive chain bearings, reducer, etc.).

Q:What is the over-current of the inverter?: External cause:?1, the motor load mutation caused by excessive impact, resulting in excessive flow.?2, the motor and motor cable phase or insulation damage to each other, resulting in short circuit turns to the ground, resulting in over-current.?3, over-current fault and motor leakage reactance, motor cable coupling reactance, so choose motor cable must be selected according to requirements.?4. Power factor correction capacitor or surge absorption device on the output side of inverter.?5. When the speed feedback signal is lost or abnormal, it will cause excessive flow, and check the encoder and its cable.

Q:What is called vector converter?: The vector converter technology is based on the DQ axis theory. Its basic idea is to decompose the current of the motor into D axis current and Q axis current, among which DVector converter

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:Can a power converter be used in a motor with small power? Will it burn the motor?: Large power converter can be used in small power motors, as long as the motor nameplate parameters, in the inverter motor parameters can be set, so that the inverter can provide the right protection.And。 Selection of frequency converter capacity, generally greater than the power of the motor more than one file.

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?: Reasonable wiring: the concrete method has:The power line and signal line of the equipment shall be as far as possible from the input and output lines of the converter.Other equipment power lines and signal lines should be avoided parallel with the input and output lines of the inverter.If the above measures are not successful, then continue the following measures:

Q:Delta inverter fault output which parameter is set?: Overload overload fault include frequency overload and overload. The electric machine may be accelerated in short time, the DC brake is too large, the grid voltage is too low, the heavy load causes. Usually by extending the acceleration time and prolong the braking time, check the power voltage. The heavy load, the motor and inverter can not drag this may be due to mechanical load, lubrication is not good. The former must replace high power motor and inverter; if the latter want to overhaul production machinery.
