Superior Control Properties
0.1s acceleration-deceleration under rated torque is attainable.
No sudden change or oscillation occurs in current phase when motor rotation reverses at zero speed.
Mains voltage is under stable control. Quick and reliable brake is available at deceleration even without dynamic brake.
Trip-Free Running
Advanced current and voltage control technology allows the AC drive to run stably without trip when alternatively accelerated and decelerated in 0.1s command.
Due to strong load capacity, the AC drive can work continuously for 20s with 180% rated load, and 1min with 150% rated load.
The AC drive offers smooth operation with large torque at low frequency under vector control mode.
Unique treatment to instantaneous power-failure
Extraordinary torque tracking function
Without special hardware detection circuit or function code setup, the AC drive can recognize motor speed, rotation, and phase angle in 0~60Hz within0.2s. It also provides smooth tracking start of freely rotating motor.
Industry Applications
The open loop vector control AC drive can be used in various industries including the wire drawing machine, film winding machine, coating machine, CNC machinery, knitting machine, jacquard machine, fan, water pump, chemical fiber, textile, synchronous linkage, injection molding machine, rolling mill, paper making line, etc.
