Variable Frequency Drives

 

 

V6-H-M1 VFD is with simple servo function, used in CNC machine tools, has the following advantages: 
Compact structure: volume equivalent to 70% of the same power inverter. 
Low speed precision machining: with excellent low frequency and large torque performance to meet the spindle processing .(it can output 180% rated torque under 0.25Hz at motoring condition).
Torque and speed indicators: excellent performance to meet the sudden load and sudden unload requirements when cutting , dynamic torque response time less than 20ms, Speed stabilization precision reach +- 0.2%.

Spindles and Variable Frequency Drives (VFD) are commonly seen on bigger budget CNC machines. However recently spindles and VFDs have become increasingly affordable. Spindles are finely tuned tools that have immense power, an impressive speed range and are very sturdy and precise.

Excellent performance under speed sensorless vector control 
Realize AC motor decoupling,enabling the DC motorization of operation control. 
the speed sensorless control of the motor four-quadrant running, torque, current, speed and DC bus voltage fast response, and the motor running stable.
Realizing 0.1s acceleration and deceleration with rated motor load. 
Upon the zero-crossing switching of the motor (forward/reverse switching), the current has no phase mutation or oscillation, and the rotating speed has no pulsation.
The bus voltage is under stable control. Quick and reliable braking can be realized when decelerating under the condition of braking without power consumption.
It is especially suitable for
The reciprocating equipment, such as numerical control machine, fountain control
machine, weaving machine and jacquard.

E5-H series high performance universal variable speed drive (VSD), is an universal inverter with simple vector control, can also realized constant pressure water supply (if proffessional function for constant pressure water supply is needed, E5-P series dedicated inverter should be selected ). E5-H series universal VSD (VFD) include following outstanding features: 
1. Sine wave PWM control with vector control; 
2. Built-in PID function; 
3. Wide voltage adaptability, AC260V~480V input, DC350V~750V input; 
4. Containing a variety of fan and water supply energy saving mode and energy saving rate selection; 
5. With sleep and wake up function. 
6. Vector control performance and insensitive to motor parameters.

commission and use, and provide many built-in features. VTdrive general purpose drives are widely available through our logistical and technical partners.

Applications
VTdrive general purpose drives can be used in a wide range of industries. Typical applications include pump, fan and constant torque use, such as conveyors. VTdrive standard drives are ideal in those situations where there is a need for simplicity to install, commission and use and where customizing or special product engineering is not required.
