Second, the application note
In the petroleum, chemical, metallurgy, mining, building materials, paper, textile, printing and dyeing, cement plants, power plants, water companies, plastic machinery plants and boiler drums, induced draft fans, central air conditioning systems and other industries and equipment, replacing backward pressure regulation Speed regulation, rectification speed regulation, DC speed regulation, slip speed regulation and mechanical manual control, regulating liquid, gas flow, flow rate, pressure and other fields, the power saving rate is as high as 20~70%; at the same time improving equipment operating conditions and production process The process, improving product output, reducing non-production delay time, reducing equipment operation and maintenance costs, etc., has significant benefits and is well received by users.
Third, the Ken cabinet high performance vector inverter features:
A power conversion scheme that uses a non-inductive vector technique to control the output voltage and frequency to change the operating speed of an AC asynchronous motor. Only the current sensor can accurately detect the change of the three-phase output AC signal and the phase angle, and automatically correct the frequency in the non-inductive vector calculation mode to achieve the effect of fixing the motor speed when the load changes.
1. Built-in parameter self-learning automatic reconciliation function, which can automatically detect the motor characteristics and automatically set its related parameters to ensure that the inverter can continue to optimize the motor running characteristics and obtain the maximum when the motor operating parameters change with time. Torque output.
2, the entire field of protection functions: low voltage, over voltage, over current, to prevent motor stall, overload, overheating and other protection.
3. Standard V/F mode, non-inductive vector mode, output power (torque) control mode.
4. Control functions designed for industrial machinery: six multi-function programmable digital input functions (99 functions are optional), three multi-function programmable digital output functions (94 functions are optional), timer/ Counter, speed tracking function, flip-flop function, automatic running function, built-in standard RS485 communication interface, can make single or multiple inverters be dynamically controlled by the main computer at the same time, and can control up to 99 inverters at the same time (super 31 units must be equipped with a relay amplifier), built-in rich PID function, an output frequency of 0.00-3200.00Hz. The technology is advanced, the structure is compact, and the product looks beautiful and generous.
5. At zero speed, it can output 0-100% adjustable torque, with zero-speed brake function, which can be applied to freight elevators, cranes and other high-end applications that replace foreign inverters.
