Perfect Power Output Section

The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:

1. No need for the additional output filter

2. Directly driving general synchronous or asynchronous motor

3. No de-rating operation on the motor

4. No dV/dt stress on the insulation of motor and cables

5. No torque ripple, extending service life of motors and mechanism

6. No cable length restriction within the acceptable voltage drop.

The general MV VFD has the following protection functions and features:

Overload and over-current

Phase loss and grounding

Over voltage

Overheat

Current limit

Redundant control power supply

Cell Bypass (optional)

Cabinet door alarm

Phase-Lock function

Synchronous Switching between VFD and Grid system

Soft start of motor

High efficiency >98% (VFD at full-load)

Electrical Isolation by the optic fiber

Built-in PID regulator

RS485 communication with the protocol, Modbus as standard, optional Profibus-DP, Ethernet,etc

Accurate fault records, easy to check fault history

Compact structure and layout, customized design is available

Q: How do I protect the inverter when the three-phase two-pole motor is running?: A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.

Q: Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power: The original you are the ordinary motor ah, this ordinary motor can not afford too high frequency. Often at high frequencies or low frequency work will burn the motor. The higher the speed, the current will increase, the lower the speed, the current will be reduced. Its power is not much change. You still with a special frequency control motor it. Frequency conversion motor is a special design, the use of frequency converter for the drive power, the motor and inverter electromechanical integrated frequency control system, so as to achieve low frequency constant torque operation and high frequency constant torque operation. This motor has good speed performance and significant energy saving effect

Q: Asus notebook power adapter how to open: Hi respectful ASUS users The power adapter can not be disassembled, and if your machine's power adapter is faulty, you can go to the local service center for testing.

Q: Laptop power adapter bad what is the phenomenon?: If you unplug the power adapter is good, then your adapter has a problem, you are the original adapter, I encountered the imitation of the adapter has this problem,

Q: Laptop power adapter problem: First, that is called the transformer, not called the charger, not with you bite the word, but you according to the charger to Taobao search, basically one hundred percent are not found.

Q: How to lift Yaskawa inverter base blockade?: Note: the base blockade is to deal with ul or ce such a special application of security agencies, meaning that when the parking limit action after the base blockade even if the program can not malfunction, relative to the emergency stop loop more harsh, they will directly cut off the power power supply. In fact, it is a white protection function, if we are not difficult to find the analysis, when over-voltage or undercurrent, the panel will show BB alarm, BB is the base block, is the base blockade.

Q: My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter: VACON frequency converter (Finland wholly owned) Model: NXL 0006 2 C1N1 Parameters: Low overload Continuous current: 6.6A 110% Overload current: 7.2A 110% Overload power: 1.5kw (ambient 40 ℃) High Overload Continuous Current: 4.8A 150% Overload Current: 7.2A 150% Overload Power: 1.1kw (Ambient 50 ℃) Maximum current: 9.6A Weight: 2.0kg Mechanical specifications: 84 x 220 x 172 Please consult the pre-sale technical support department

Q: What is the frequency of `30 points: AC are frequency, China is 50 Hz, is in a second amplitude of 50 times. To change this frequency, it is necessary to use some electronic components to change the current frequency. General frequency conversion for the tributary motor speed more. So that some equipment can be stepless. Principle, see the first floor just fine, copy the more detailed.
