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: What are the modes of operation of a frequency converter?: Frequency converter with motor no-load operation, 11 set motor power and pole number, to consider the work current of the converter. 21 set the maximum output frequency, frequency and torque characteristics of the inverter. VPf types include items such as maximum frequency, basic frequency and torque type. The highest frequency is the highest frequency that the inverter motor system can operate, because the highest frequency of the inverter itself may be higher, when the highest frequency allowed by the motor is lower than the frequency conversion

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?: 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 function of a frequency converter on an electric motor?: Through the frequency converter, the motor can be adjusted speed, so as to obtain the speed required by itself, and also can reduce the motor running current and save energy and reduce consumption.

Q: What does the RUN key on the inverter mean? How do you use it?: In general, when selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button. Press it, the converter will run, turn or reverse

Q: What is the difference between SIEMENS inverter and built-in filter?: SIEMENS built-in filter optional three. Class a EMC filter. B class EMC filter. LC/ sine filter.Power 110KW to 250KW converter, optional external or built-in level a filter,The power 7.5KW to 15Kw converter, in addition to additional B class EMC filter, can be equipped with a class EMC filter.The LC/ sinusoidal filter can effectively suppress the rise of voltage and capacitance charge / discharge current in the variable frequency drive. But there are many restrictions: only V/F is allowed. FCC control mode. To comply with the 15% drop capacity, the output frequency limit is 150HZ, and only allowed to operate at the 4KHZ pulse frequency. In operation and debugging, the LC sinusoidal filter must be connected to the motor.

Q: What is the TTK converter produced?: Characteristic：Compact structure design, flexible installation, advanced control algorithm: space voltage vector control technology, power failure restart, automatic voltage adjustment, dead time compensation, energy saving operation,The main and auxiliary setting, built-in PID, simple PLC, oscillating frequency and zero frequency difference, length control, precision control requirements; design and test in accordance with international standards, to ensure the reliability of the product; choose rich accessories.

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: How do you set the frequency with panels?. What are the specific steps?: Concrete steps are:1, the parameter 700 is the starting signal, the 1 is the panel button starting, and the 2 is the external signal starting;2, the parameter 1000 is the frequency setting value, and the 1 is the panel lifting mark key to change the frequency, and 2 is the external analog signal change.3, the starting signal is set automatically, then the parameter 1000 is 1, the panel is set frequency, and the parameter 1031 is set to 1 so that the frequency value after the change is saved automatically.

Q: I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: The general frequency converter adopting vector control mode can not only match the DC motor in the speed regulation range, but also can control the torque generated by the asynchronous motor. The vector control method is based on the parameter of controlled asynchronous motor accurately, some general inverter needs accurate input parameters of asynchronous motor when in use, some general inverter needs to use the speed sensor and the encoder. In view of the motor parameters may change, will affect the performance of inverter for motor, the model of vector control of induction motor parameter automatic detection, automatic identification, adaptive function has the general inverter, can automatically to motor parameter identification before with the function of the general inverter for normal operation in the asynchronous motor, and adjust the control related parameters in the algorithm according to the identification results, thus effectively to ordinary asynchronous motor vector control.
