ACH200 series products are the third generation of high-performance high-voltage vector-type AC drive made by VEICHI Electric on years of technical accumulation and in-depth market research and demand analysis, which adopts mature power unit series technology, DSP+FPGA dual core control, vector control algorithm, to deliver high control accuracy, fast dynamic response, large low frequency output torque etc. It is widely used in fans, pumps, compressors, belt machines, ball millscrushers and other load occasions, providing the drive core for energy saving and emission reduction to meet the diversified needs of industrial enterprises.
DSP+FPGA dual-chip control structure, control algorithms implemented by DSP, and external signals such as IO, bus and encoder processed by FPGA in parallel. High-speed and high-precision loop control ensures the excellent dynamic response capability and control accuracy.
>>> Start with high torque and low frequency
Open-loop vector control: 0.5Hz 150% starting torque.
Closed-loop vector control: 0Hz 200% starting torque.
200% rated torque output at 0Hz for IPM motors under open-loop control by highfrequency signal injection.
Current waveform is nearly sine wave at low frequency.
Motor resonance will not be caused at low frequency.
Track rotational speed accurately regardless of the motor speed states. (forward, reverse, still).
The whole process from starting to targeted state can be completed in shorter than 200ms with fast response.
Remanent voltage is larger at shundown of large inertia equipment, so its remanent and phase can be estimated after restart, and then enter rotary preexcitation and acceleration.
CAN or fiber optic communication are adopted to ensure real-time communication and output consistency among multiple machines regardless of mechanical load and fluid load.
Phase-locked technology enables motor to start and run without interfere between power frequency and variable frequency, so it's suitable for switching between multi-gear water pumps. The impact current of the switching process does not exceed 1.5 times of the rated motor current.
85%-110% full-load output.
65%-85% derated output.
110%-120% derated output.
Grid-side THD value smaller than 2%.
Motor-side THD value smaller than 2%.
