Q:What is the frequency converter AVR?
When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.
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:Frequency converter OC alarm, what's the matter?
I guess the original intention of the inverter circuit designer is this: when the power test module has broken down, or the operation of the module endangering the safety of the module, even the module has been damaged, it will promptly report the OC fault. The cause is generally a load side, a short circuit or a heavy loadThe load causes excessive overcurrent, or over current or even short circuit due to bad drive or damage of the module itself.
Q:What is the difference between inverters and inverters?!!
Inverter inside the circuit is inverterIt is a control of communication -- direct current -- CommunicationDC alternating current is called inverter
Q:The difference between soft starter and converter
The soft starter is just a thyristor pressure regulating device is simple to start the motor, the motor speed can not be normal, low price; inverter is the AC power supply voltage and frequency, can IGBT chopper can be used to start the motor, can also be normal speed, the price is relatively expensive
Q:How can the interference caused by frequency converter be solved?
Shielded interference source: shielded interference source is an effective way to suppress interference. Usually the inverter itself with iron shielding, can not let the leaked electromagnetic interference, but the output line frequency converter is best to use steel shielding, in particular to an external signal (4~20mA signal output from the controller) control of inverter, the control signal line is as short as possible (usually less than 20m), and must use the shielded twisted pair and the main power line and the control line (AC380) and (AC220V) completely separated. In addition, the circuit of electronic sensitive equipment in the system also adopts shielded twisted pair, especially the pressure signal. All signal lines in the system must not be placed in the same pipe or slot as the main electrical line and control line. To make the shield effective, the shield must be grounded reliably.
Q:What is the difference between inverter energy consumption braking and motor energy consumption braking?
The reverse brake has one of the biggest disadvantages: when the motor speed is 0, if the power supply is not removed in time, the motor will reverse. There are two methods to solve this problem: 1, in the control loop of the motor power supply phase, adding a time relay, when the brake after a period of time, disconnect the power after inversion, so as to avoid motor reversal. But the braking time is difficult to estimate because of this method, so the braking effect is not accurate. 2. A speed relay is added to the control circuit of the motor's inverting power supply. When the sensor detects the speed of the motor is 0, the inverter power of the motor is cut off in time. Because of this method, the speed relay monitors the motor speed in real time, so the braking effect is much better than the last one. It is precisely because reverse braking has this characteristic, therefore, it is not allowed to reverse the machinery, such as some lathes, etc., the brake method can not use reverse braking, and can only use energy consumption braking or mechanical brake.
Q:What are the possible causes of frequency hopping overload?
If the motor and inverter adapter, because the motor overload in inverter, this time is called the overload overload of the transducer, the current inverter rated current is compared; if the motor rated current is less than the rated current of inverter, the correct input motor nameplate and protection, the overload protection is often referred to as motor overload protection. Therefore, we must distinguish the specific circumstances of the current protection. Because of the overload point of the converter and the overcurrent point of the converter, the two protection alternates frequently.
Q:How to solve the interference problem of frequency converter?
If only the temperature measurement fluctuations, as the temperature is slow change, the filter is more effective way, the filter can use a passive RC low-pass filter, and then connected to the patrol instrument on the terminal can.
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,
