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: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:Can the inverter be used to control the speed of the DC motor?
The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
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.
Q:Laptop power adapter (no power supply, but indicator light)
Notebook power adapter can not charge, but the indicator light does not light the common reasons are: 1, the power adapter is broken or the connector is broken. 2, the power adapter output problem, no output or output is too low, can not give the computer charge. 3, the notebook charging interface is broken, not into the electricity charge. 4, the notebook power management circuit out of the fault, resulting in can not charge.
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:Who knows how the inverter is calculated?
Quadrupole motor synchronous speed is: 1500 r / min, but the actual motor speed will be more than 14 turn.
Q:380V 2 pole motor can use the inverter?
Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
Q:Can the laptop 1.3a power adapter be used on a 1.5a device?
No, use a power adapter that is equal to or slightly larger than 1.5a.
Q:Fuji inverter motor set the number of poles will not have any effect?
The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
