AC80C Product Features Excellent Vector Control Performance Oscillation suppression Realizing AC motor decouple and motor vector control . In PG without vector torque control mode , torque control accuracy can up to 5% . Motor four - quadrant runs; torque , current , speed and DC bus voltage fast response , and the motor runs smoothly . when the motor can not run properly with significant oscillations , turn on this feature , the oscillation suppressing effect would be significantly improved.

Load Output current Output current Outputing large current at 2HZ, the motor does not stall VF open oscillation suppression Random function carrier Compared with the sharp fixed carrier motor noise , output voltage harmonic spectrum random carriers uniformly distributes over a wide frequency range , and the noise emitted by the motor is softer . Output current Output current FFT Current wave under oscillation Overvoltage stall function When large inertia load deceleration stop , the drive automatically limiting voltage to run. Random carrier OFF Output current Current Frequency FFT Voltage Random carrier ON

Speed tracking restart function Instantaneous stop non - stop function The drive can judge the motor speed and direction , and then start with the motor speed tracked corresponding frequency to start the motor which is in rotating state . Larger tracking frequency range speed tracking , traceability can reach the lowest speed of 1Hz . This function is momentary power failure will not stop the drive . In the case of a momentary power failure or a sudden drop in voltage,the drive to reduce the output speed and load feedback energy,reduce the offset voltage in order to maintain the drive to run a short time .

Running coefficient Output current Bus voltage Output current Output frequency Over - excitation function No need to increase peripheral resistance braking and other accessories , to achieve rapid braking effect and improve product usability . It can effectively inhibit the decelerating bus voltage rises , to avoid frequent reported overvoltage fault , while achieving rapid braking power to realize fast stop . Smart AVR function When the automatic voltage regulator function is invalid , the output voltage would change with the input voltage .

When the automatic voltage regulator function is valid , as long as the minimum input voltage fluctuation is greater than the programmed output voltage (motor rated voltage), the output voltage can be substantially maintained at the set value . Current Frequency Voltage Bus voltage The output voltage Overexcitation braking function effective Smart AVR function invalid Strong background software Support the drive parameters operation and virtual oscilloscope function ( virtual label can realize the internal state monitor of the inverter graphics ) . Bus voltage The output voltage Smart AVR function valid 03-04
