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 can be fulfilled with built-in braking units for the inverter below 15kw and external braking resistors for that above 15kw

Hi-efficiency Energy-saving control
Wonderful energy-saving function beyond imagination, the hi-efficiency energy-saving control reaches the maximum effect in theory

Low Noise Operation
High carrier frequency SPWM modulation type may greatly suppress the noise, which is especially suitable for the place with limitation for noise.

Perfect Power Ultraharmonics 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 ultraharmonics of power.
