ac drives Frequency converter four quadrant (Frequency Inverter )

HPVFQ inverter is specifically designed for accurate speed adjustment, with excellent performance, stable and reliable. The goal is high-power output, convenient use, high security. This inverter possesses auto tuning. PID control, multi-speed control and multi-functional input/output control etc.

Main characters

HPVFV inverter, using high-performance digital signal processor and optimizing control algorithm, provides fans and pumps etc with high speed, flexible, safety control.Including V/F control, field orientation vector control, Sensorless Vector control (this control can effectively improve the problem speed along with the change of load). PID function and auto tuning function are more suitable for fans and pumps to realize better energy saving.System startup or reaching set value, through the S-Curve function, can realize smooth change of speed, so as to improve the large inertia load control functions.

Main features

Perfect protection function

Over voltage, over current, low voltage, over temperature, over load,Zero-sequence current, out of control.

Torque controlQuick torque response for the changable load(low speed with high torque)Starting output torque 150%1) Reversing deceleration control2) Stop torque controlNo feedback device, correct torque controlSynchronous run control

Double speed run controlPID control founctionPID control buile_in, is mainly applied in process control to control flow rate, temperature, pressure etc. Use proportion, integral, differential realize variable closed-loop control. To add the PID processing controller out side the speed control loop. So the inverter, without PID controller and PLC, can realize many kind of function. PID compensation function can be used in control of the scroll tension.

Communication proceduresProfibus,Modbus,RS485/232C,CAN-Monitoring function-Provide communication program (option)-Fault Trace

Fault TracePreservation current, voltage, frequency, torque, etc. in l second before trip.Flying startRestart for deceleration load and instant power failure.Auto tuning Automatic measurement motor parameters with simple operation, reflect the best control function.
