Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Analog input signal is particularly vulnerable to external interference, so the general use of twisted shield as a signal line; and wiring as short as possible, generally not more than 20 meters; if some use conditions are vulnerable to external serious interference, the analog signal Side need to add a filter capacitor or ferrite core.
Q:What is the frequency of `30 points
frequency conversion By changing the AC frequency of the way to achieve AC power control technology is called frequency conversion technology
Q:The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Motor speed formula: N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (s); F - power frequency (hz); P - pole pairs of motor rotating magnetic fields.
Q:Yaskawa inverter reported base blockade what is the reason?
For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
Q:Which machines are used for the frequency converter
Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply, air conditioning and other fields.
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
If you buy the inverter and the motor can match, it is certainly the quality of the inverter.
Q:65w adapter and 90w laptop power adapter What is the difference?
According to ibm specification T6 x6 r6 series power supply is compatible The difference is x6 this thin model with 65 The official explanation is (original English), in the 90w models using 65w machine may be in high power consumption, can not meet the system requirements. That is, while the side of the charge side of the use, it is possible that the computer can not run at full speed. In fact, the use of and there is no problem, but also little, at least the machine is no harm. For psychological factors, you can buy a 90w, Taobao fake a lot, you are not professional or to Jingdong to buy, about 250 yuan, although it is more expensive, really is the original.
Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
Power will drop, down to the original one-tenth
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
