needs.

  

Features of EDS1000  frequency inverter:

   • Sensorless Vector Control develops high torque over a wide speed range and adapts to individual 

      motor characteristics.

   • 150% overload for 60 seconds or 200% overload for 0.5 seconds provides robust ovrload protection.

   •Timer, Counter, Basic Logic functions can reduce hardware design costs and simplify control schemes.

   •Two analog input channels, including PID capability,offer enhanced application flexibility.

   • Variable PWM allows the drive to output more current at low Frequencies(1Hz).

   •An integral keypad provides out of the box operation using the local potentiometer and control keys.

   • A relay pre-charge limits inrush current.

   • Integral RS485 communications let the drives be used in a multidrop network configuration.

Q:Laptop power adapter aging
This is not much relationship with the adapter, is your laptop internal hardware overheating, leading to self-protection open and shut down.
Q:Speed of 3000 r / min three-phase motor how to change its speed
The key lies in two points: 1, you ask the variable range is how much? 2, your motor had a few qualifying? If your motor is 6 outlet, and you only need to speed, plus your motor is also an asynchronous motor, and you do not have the requirements of the load; then congratulations, you can achieve "speed" You just put the motor wiring way to do a △ - Y or Y - △ conversion can be achieved. If the above conditions you have one or two can not meet, then your best way is to buy a drive to achieve the variable speed. Of course, you can also make some changes to the winding to achieve the so-called single-winding multi-speed operation (this change, but the need for a certain technical content).
Q:The emitter E of the inverter inverter module and the AC output U are not directly connected together
Corresponding to a phase of the branch of the IGBT inverter module generally appear in pairs
Q:Laptop power adapter repair how much money
Different notebook power adapter models are different, the price gap is large.   Maintenance costs to see the specific model and damage level position. Generally do not recommend maintenance, it is recommended to replace the more appropriate. If you are not covered by the warranty period, you can repair free of charge. Hands-on ability to recommend self-repair, pay maintenance department recommended. After all, once again a greater chance of damage.
Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
The belt rotation is calculated by the speed ratio. The current transferred to the motor by the inverter is approximately equal to the rated current of the motor, ie the motor's power is maximized.
Q:Does the teacher know the working principle of the inverter?
Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.
Q:Can the notebook's power adapter be mixed?
In general, the same brand of notebook power adapter, as long as the same wattage, the same interface, can be mixed with. But do not recommend different brands or different wattage power adapter mix. Because the output wattage is different, there may be damage to the notebook, such as voltage instability and so on.
Q:How does the variable frequency motor output torque at very low frequencies?
1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.
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%
