Q:How to learn the inverter debugging and design parameters
Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
Motor current when the current 10A this has no effect on you, the rated current is 31.4A, your inverter is selected how many W, is the fan pump type or universal? Now the motor operating current reached 34-35A, more than the rated current, then the motor may have two problems, one is the motor leakage powerful, and in a motor is overload, resulting in increased current
Q:30 kW 6 pole frequency motor torque is how much
Look at the motor sample or nameplate, above some Different manufacturers of the motor may be different I have a sample on hand, 90KW, six pole, frame number 315M1, rated current 168A, rated torque 859.4 And then look at your inverter performance and motor performance, and can generally be overloaded to the rated torque of 150%
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:Siemens g120 inverter torque limit what is the meaning
Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
Q:Laptop power adapter in the ring is how is it?
Inductance and capacitive shock sound In fact, any inductance and capacitance work will be shocked, but some shocks are large, and some shocks are small, the frequency is not the same, and some sounds harsh, some not harsh, and some ears can not hear the range Inside. Of course, this noise also has a certain standard, in fact, listen carefully, a lot of more power consumption of electronic equipment (tens of watts or more) have a voice. So, as you said to hear the sound is very small, sharp degree is not the same. This do not control, as long as they can endure, the general sound is not great, rest assured that good use of the performance and stability of no effect.
Q:How do I select a drive? Which brand is better
  8, drive explosion-proof motor, the inverter is not explosion-proof structure, the inverter should be set in a dangerous place outside.     9, the use of inverter drive gear motor, the use of the gear by the part of the lubrication part of the lubrication control. When lubricating oil is lubricated, there is no limit in the low speed range. If there is a high speed range above the rated speed, there is a risk that the lubricating oil may be used. Therefore, do not exceed the maximum speed allowable value.     10, the inverter drive winding rotor asynchronous motor, most of the use of existing motor. Winding motor and ordinary squirrel-cage motor compared to the winding motor winding impedance is small. Therefore, it is prone to overcurrent trip due to ripple current, so a frequency converter larger than the normal capacity should be selected. General winding motor for flywheel torque more occasions, in the set acceleration and deceleration time should pay more attention.
Q:Inverter alarm a043, how is it
When a signal failure occurs, use the DTI board, if necessary, change P215. With P806 (Follow the parameter description) during operation can be converted to no encoder operation A043 is: n-actjump exceeds the allowable change speed of the speed encoder signal (P215) In addition, for the synchronous motor (P095 = 12): The motor speed is 2% higher than the inverter release time point. The inverter in the ready state can not exit. Check processing: Check if the cable is disconnected Check the tachometer to shield the ground Not only on the motor side but also on the inverter side The encoder cable does not allow disconnection Use only recommended encoders The encoder cable is not allowed to be laid with the power cable
Q:The inverter is running independently
Frequency conversion regulator is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power supply according to the breaking of the internal IGBT, and provide the required power supply voltage according to the actual needs of the motor, so as to achieve the goal of saving energy and speeding.
