Second-ranking low-frequency great torque, overload ability strong, quick dynamic response: it is widely used in plastic injection machine, hoist, machine tool, cutting machine, steel metallurgical industry, etc. Second-ranking carrier frequency automatic adjustment: according to temperature and load characteristics, ensure the carrier frequency automatic adjustment quiet operation. Second-ranking rapid acceleration and deceleration time (0.1 s the acceleration/deceleration) : satisfy fast brake, accurate location requirements, applicable to bag making machine, a high-speed vacuum forming equipment, etc. Second-ranking dc bus scheme: the system by a public rectifier unit (or rectifier/feedback unit) after rectifying dc bus can drive through some Taiwan inverter. Electrical braking energy produced after dc bus can automatic equilibrium, supply electromotion state of motor used in from the electric energy can reduce power absorption, compared to traditional inverter system further energy-saving. Suitable for papermaking, chemical fiber production line, cranes, etc. Second-ranking closed-loop torque control: by adding a PG card (option) testing the motor speed realizing closed-loop torque control, makes the output torque converter with load changes can instantly adjustment. Second-ranking fixed-length control: length through switch quantity or high speed pulse input terminals input pulse signal calculation, when the actual length reach a set length output switch quantity signal, which can be used for cutting length setting. Second-ranking prolapse control: when multiple frequency converter drive the same load, because at different speeds cause load distribution imbalance, make speed larger inverter inherit a re-load. Droop load control characteristic as the increasing speed droop changes. Can make balanced load distribution. Second-ranking introduction LCD panel: not only can display 4 do Chinese, convenient operation, but also Chinese users with parameter copy function, what can realize rapid group frequency inverter parameter copies, greatly saves the commissioning of the time, ensure the consistency of the group inverter function. Second-ranking unique shortcut menu button: provide a more rapid view and modification methods of function parameters. Users can general function parameters on the shortcut menu, convenient at any time, accelerate users to examine equipment control or malfunction reaction. Second-ranking constant tension control: by tension curly card (option) built-in coil diameter computing functions can realize rewinder and rewind control, direct/indirect tension control, can be widely used in wire drawing machine, papermaking, printing, plastic packaging, textile sizing woven shaft winding and roll dyeing machine fabric reel roller, etc. Second-ranking constant pressure water supply control: the water supply control card (option) can realize supply pressure closed loop, multiple pump automatically switch, first at first stop, dormancy of timing, water supply and other functions, guarantee of pumps running time average, prolong service life, widely used in waterworks, residential water supply, heating, central air-conditioning. CHV series of high-performance vector inverter adopts industry-leading modular design, double CPU control, 16-bit DSP chip complete current vector core algorithm, including motor parameter self-learning, 32 bit low power consumption MCU chip adopt RISC instruction set, speed up 25ns/commands, responsible for complete function of high speed computing, and software DSP chip of data exchange, etc. Two hearts "heart" each, the coordination, combine to make CHV vector frequency converter performance of the standings, outstanding. CHV another breakthrough innovations is according to the different characteristics of industrial application design different functional expansion card, will industry applications solutions placed inside expansion card, users only a piece of expansion will get industry inverter function, accomplish truly low-cost realize user customization system. Meanwhile expansion card can also realize function combination, and gives users the secondary development platform, users of complex control to cope.
