ALPHA6000V Series Close Loop Vector Control AC Drive

ALPHA6000V series AC drive is a highly effective product under close loop vector control. It truly realizes the decoupling of AC motor and control manner of DC motor, due to the adoption of the world’s leading technology of current vector control and torque control.

ALPHA6000V series AC drive takes advantage of PG vector control mode (close loop vector control). Thus, it offers more distinguished control performance to meet much higher requirements in industries.

Technical Characteristics

Wide input voltage fluctuation range reaches±20%.

Built-in RS485 communication is in favor of MODBUS-RTU protocol.

Flexible frequency mix-given function is provided.

Multiple programmable I/O terminals.

Support a range of extension cards including I/O, PG, communication card, and more.

Four control modes: V/F control, Non-PG vector control, With-PG vector control (Close-loop vector control) and V/F separation control.

Outstanding Control Performance

0.1s acceleration-deceleration under rated torque
No sudden change or oscillation occurs in current phase, while motor rotation reverses at zero speed.
Mains voltage is under stable control. Rapid and dependable brake is available at deceleration even without dynamic brake.

Trip-Free Running

State-of-the-arttechnology of current and voltage control allows the AC drive to run stably without trip when alternatively accelerated and decelerated in 0.1s command.
With strong load capacity, the AC drive can continue working for 20s with 180% rated load, and 1min with 150% rated load.
The AC drive runs stably 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 still recognize motor speed, rotation, and phase angle in 0~60Hz within 0.2s. Smooth tracking start of freely rotating motor is provided.

Industry Applications

The close loop vector control AC drive can be applied in the crane, film winding machine, coating machine, CNC machine tool, knitter, jacquard machine,hoisting equipment, rolling mill, paper making line, textile machine,chemical fiber, synchronous linkage, and more.
