Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
Communication can reach a longer and more stable, generally better of the city 485
Q:Inverter alarm a043, how is it
Check processing: Check if the cable is disconnected. Check the tachometer to shield the ground. The shield is not only on the motor side, but also on the inverter side The cable of the pulse encoder should not be disconnected. The pulse encoder cable can not be laid together with the power loop cable. Use only the recommended pulse encoder.
Q:With the inverter control fan 37Kw4 pole with what model inverter
Control the fan: select the fan pump with 37KW or 45KW inverter.
Q:What is the output voltage of the laptop power adapter?
16V to 20V, different brands may be different, 19V, 20V more.
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:What is the difference between variable frequency motor and variable speed motor?
The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,
Q:What is the common COM point of the PLC and the inverter? Is it positive?
Generally refers to the common, and most of the negative
Q:Short-term short-circuit converter DC link positive and negative will damage the inverter?
the switch signal Is the fan running up after the speed line is low, this can be shorted. Pulse is every turn a circle, send two pulses to the speed line
Q:400w 6-pole motor should be equipped with much of the inverter?
400w 6-pole motor with frequency converter, as long as 1kw inverter can be a.
Q:Why the number of motor poles increased, the inverter capacity will increase
The relationship between the motor current and the power is The power is equal to the current and voltage of the product again good with the power factor. (Simplex)
