Product Description
QD800 series inverter is a versatile high-performance current vector inverter, mainly used to control and regulate the speed of three-phase AC induction motor. QD800 high-performance vector control technology, low speed high torque output, good dynamic characteristics, superior overload capacity, increase the user-programmable function and background monitoring software, communication bus, support for multiple PG card, combinations feature-rich, powerful, stable performance.
Product Advantages:
1.It supports communication via Modbus-RTU,PROFIBUS-DP, CANlink and CNAopen
2.it support three control modes,namely,sensorless flux vector control(SVC),closed-loop vector control(FVC) and V/F control.
3.The background monitoring software helps to achieve function of parameter upload&download and a real-time oscilloscope.
4.The QD80pc1 programmable card enables you to write programs in ladder diagram
Its programming environment is compatible with that of the QD series PLC
5.we care about not only your investment income,but also the running cost and maintenance expenses. We will always engage in making you obtain the most return with the lowest investment to realize your profit maximization.

Fast current limiting functionMinimizing flow failures, protect the normal operation of the inverter
Torque limit and control"Excavator" characteristics, the torque limit automatically during running, prevent frequent over-current trip; The torque control closed-loop vector model is achieved
Individualized
function
Outstanding featuresBased on current vector control technology of asynchronous motor control
Instantaneous stop constantlyInstantaneous power failure through load feedback energy compensation voltage is reduced, maintain frequency converter in a short period of time to continue running
Virtual IOsFive groups of virtual DIDO, suggested that logic control can be realized
Timing controlTiming control function: set time range 0.0 Min to 6500.0 Min
Motor switchTwo groups click parameters, which can realize two motor switch control
Support multithreading busSupport: four kinds of fieldbus Modbus, profibus-dp, CANlink, CANopen
Motor overheating protectionOptional IO expansion card 1, click on the temperature sensor input analog input AI3 acceptable (PT100, PT1000)
Support more encoderSupport the difference, open collector, the sale, rotating transformer, such as is cosine encoder
