Q: What is the difference between a frequency converter and a servo controller?: Servo system: 1 servo drives in the premise of the development of frequency conversion technology, the current loop in the internal drive, speed loop and position loop (inverter without the ring) of algorithm operation and control technology is more accurate than the general frequency, but also in the function than the traditional servo many powerful, the main point can accurate position control. To control the speed and position of the pulse sequence controller sends the (of course there are also some integrated servo control unit or by bus communication way directly to set the parameters of position and velocity in the drive), drive the internal algorithm and faster and more accurate calculation and better performance of electronic devices to be more superior to converter. 2, motor servo motor of the material, structure and machining process is much higher than that of the AC motor drive inverter (general AC motor or constant torque, constant power and other types of motor), that is to say when the power driver output current and voltage and frequency change quickly, the servo motor can generate action response according to the change power changes, response and anti overload capacity is much higher than that of AC motor inverter drive motor, fundamental serious differences is two different performance. That is to say, not the inverter can not change the power supply signal, but the motor itself can not respond, so in the frequency of the internal algorithm settings, in order to protect the motor to do the corresponding overload settings. Of course, even if the output power of the inverter is not limited, some high-performance inverters can directly drive the servo motor!

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: It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): Has the frequency converter been used for a long time? The inverter power placed on the two day, and then open, put the line inside the head plug again, and then boot general can solve the problem, new don't try

Q: Can the frequency converter 7.5KW take the motor with 11KW?: Inverter 7.5KW can not take 11KW motor, so that may cause overload inverter.Usually, the frequency converter 7.5KW can take about 5KW motors.

Q: Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: Mainly below the basic frequency of speed regulation,If higher than the basic frequency, that is constant power speed, that is, the higher the motor speed, the smaller the torque

Q: Today, I was asked the question, and I also brought it to you to share the following Oh!: The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.

Q: How can I control the frequency converter with a computer?: RS232 communication can be used to control the frequency converter and other equipment, but there are several problems to be solved:1, frequency converter is generally two wire communication (422/485), so there must be 485/232 or 485/USB conversion.2, software problems, you can use VB, C, and with any of their own familiar with the method of preparation of a control interface, and in accordance with the frequency converter communication protocol written.3, also can buy ready-made configuration software, that saves the trouble of programming and debugging program.4, with computer communication with PLC (currently popular), and then use PLC and frequency converter communication (program is more simple and practical than using VB).

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: Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.

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.
