Product Description:

Medium Voltage Drive VFD 1250KW 6KV HIVERT-Y 06/154

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.

 

Features

Front access design for easy maintenance of power modules that can be replaced in just a few minutes.
∙ Single power cell design for all modules allows reduced spare parts inventory cost.
∙ 2-Quadrant and 4-Quadrant versions available.
∙ Fibre-optic interface for safe control and feedback communication with controller.

 

Monitoring(HMI)

Door-mounted easy-to-use 7-inch color LCD touch-screen Main panel
∙ User-friendly interface with operational data at your fingertips
∙ Virtual meters display main VFD parameters
∙ System and status monitoring and manual controls
∙ Power module status monitoring
∙ Data logging, trending displays, diagnostic information available
∙ Multiple languages available
∙ Parameter adjustment and operation records
∙ Dedicated multi-level menu to guide user with different access levels for service and commissioning engineers (Operator, Manager and Administrator)

Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
Is it right? The next manual to see do not understand
Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?
Such a high speed estimated motor can not reach, to increase the gearbox Specific algorithm: n = 60f / p P is the number of pole pairs, f is the frequency. The pole pair number of the 6 pole motor is 3. F = n * p / 60 = 8000 * 3/60 = 400 Hz.
Q:Can the inverter be used to control the speed of the DC motor?
For the brush commutation DC motor, the speed of the output torque in a certain circumstances and the input voltage related. For this type of motor, use the inverter to control the output of the rectifier device that supplies power to the motor, which can control the speed. For the brushless DC motor, the controller is in accordance with a certain law to change the form of stator winding power supply to produce a rotating magnetic field to drive the rotor rotation. That is, the DC motor controller outside the part of the AC motor and the structure and the principle has not much difference (see below. For such motors, with the inverter to replace the controller, and control the same as the AC motor Control the speed.
Q:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
The existing Taian inverter 380V3.7KW can bring 4.0KW 2 pole motor, 18000 to 300HZ can also see how you load, It is best to check your wiring tightness and whether the load is stuck. It is recommended to use the N310-4005-S3 this model, such as with the E510-405-H3 better.
Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
If it is normal V / F control, then do not need to modify too many parameters to limit the frequency limit of 50%
Q:What is the difference between the collector and the emitter mode?
This physical structure is intended to facilitate the need for positive enlargement.
Q:What are the AC motor speed control methods? What are the characteristics of each
1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
If you worry about the small, with 18.5KW is far enough.
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: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
