ALPHA6000S Series Open Loop Vector Control AC Drive

ALPHA6000S series AC drive is a high-performance product under open loop vector control mode. Adoption of the international leading technology of current vector control and torque control allows this product to really achieve the decoupling of AC motor and control manner of DC motor. The superior control attributes of our product can fully satisfy the motion drive requirements of our customers.

Technical Characteristics

Input voltage fluctuation range is ±20%.

Built-in RS485 communication supports MODBUS-RTU protocol.

Flexible frequency mix-given function

Multiple programmable I/O terminals

Abundant fault-protection and running-monitor functions

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

Three control modes including V/F control, Non-PG vector control, and V/F separation control.

V/F Control
It features superior control performance of vector control. Also, it is insensitive to motor parameters.
Start Torque
0.5Hz/ 150% rated torque
Speed Range
1:100
Steady-State Precision
±0.5%
It can control the motor to run stably with 150% rated torque at 0.5Hz.
Non-PG Vector Control (Open Loop Vector Control)
Independent current loop control guarantees the real torque control. It supports the immediate switching between torque control mode and speed control mode.
Start Torque
0.5Hz/ 180% rated torque
Speed Range
1:200
Steady-State Precision
±0.5%
Torque Precision
±5%
Torque Response
﹤20ms
It can control the motor to run smoothly with 150% rated torque at 0.5Hz.

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.
