Vector Control Frequency Inverter We offer to our clients Closelosop Vector Control Inverter Q9000 series. It is a kind of high performance vector control inverter used across on a global platform. The prevailing vector technology and advance modern control theory is used to provide maximum torque during operation at low speed and thus achieving high performance level. These are equipped with four control modes. Without PG vector control, it is capable of reaching high torque and failure free operation from a low speed at 1%. Moreover, it can easily obtain high torque operation speed at 0 speed, when equipped with PG control. These products serve as a ideal choice for improving quality & productivity.
Some of the pertinent features of our range of products are:
- Perfect Current Vector Control: By means of simultaneously controlling the primary current and its phase, the magnetic field current and torque current can be controlled respectively and individually to obtain a smooth run, a speed control and torque control with high torque and high precision at a very low speed
- Various Control Functions: PID control, slip compensation function, speed search, over/lower torque detection and energy-saving operation control function
- Excellent Torque Characteristics: Even if without PG, a high torque of 150%/0.5Hz can be reached
- Powerful Braking Function: Powerful braking function is performed by built-in braking units for the inverter below 15kw and external braking resistors for that above 15kw
- Hi-efficiency Energy-saving control: The hi-efficiency energy-saving control reaches the maximum effect on books. Offer wonderful energy-saving function beyond imagination
- Low Noise Operation: High carrier frequency SPWM modulation type greatly suppress the noise, hence, considerably reducing the noise pollution.
- Perfect Power Ultra harmonics Suppression Countermeasures: Built-in DC reactor for the purpose of improving power factors is equipped for all series of 55kw and above; DC reactor wiring terminal is reserved for the units below 55KW for your choice of DC reactor to reduce the interference of the ultra harmonics of power.
Apart from its primary functions, Q9000 also performs several other functions, thus satisfying various needs of distinct users. This machine is widely know for its mulch-utilities such as:
- Standard built-in PID feedback control may provide a precise closed loop control
- V/F separation and free V/F image function may fully meet any special requirements of various motors
- Powerful auto tuning function enables all kinds of motors to run effectively
- Whatever precise machinery or multi-motor operation, there are four control modes combined closely to fulfill best running
- High torque at low speed and smooth acceleration/deceleration in whole frequency domain
- Simple and flexible operation is suitable for various operating conditions
- Expanding function applies to stand-alone or network
