Description:Features and applications: 1) Power range: 2.2 ~ 315kW (3AC 380V, -15% ~ 15%) 2) Output frequency: 0 ~ 600Hz 3) Control mode: vector control without PG, vector control with PG, V/F control 4) Overload capacity: 150% rated current 60s; 180% rated current 10s 5) Speed control accuracy: ±0.5% of max. speed (SVC); ±0.1% of max. speed (VC) 6) Starting torque: 150% / 0.5Hz (SVC); 180% / 0Hz (VC) 7) High torque at low speed, powerful overload capability and fast dynamic response: wide application in such industries as injection molding machines, lift, crane, textile, pulp and paper and steel metallurgy 8) Automatic carrier frequency adjustment: automatic carrier frequency adjustment according to the temperature and load features to ensure mute operation 9) Fast acceleration (deceleration) time (minimum 0.1s): meets the requirement for fast brake and accurate positioning, applicable to bag-making machines and high-speed forming machines 10) Common DC bus solution: a common rectifier unit or rectifier feedback unit feed energy to several inverters through DC bus. The energy generated upon motor brake can implement automatic balance through the DC bus, and supply power for the motor. Thus, the electric energy absorbed from the power grid can be reduced. The system is energy-saving, which is applicable to such industries as paper-making, chemical fiber production line and cranes 11) Closed loop torque control: a PG card (optional) is used to detect the rotation speed of the motor to implement closed loop torque control so that the output torque of the inverter can be adjusted instantly in real time with the load change 12) Fixed length control: the length is calculated according to the digital input or the high speed pulse signal input 13) Frequency droop: if multiple inverters drive the same load, different speeds may cause unbalanced load allocation, so that the inverter with higher speed will bear heavier load 14) External LCD panel: the system can display four lines in Chinese to facilitate operations of Chinese users, and meanwhile it supports the parameter copy function 15) Unique shortcut menu button: provides fast functional parameter viewing and modification method 16) Constant tension control: the built-in roll diameter calculation of the tension control card (option) can implement winding (unwinding) control and direct (indirect) tension control 17) Constant pressure water supply control: a water supply control card (option) can implement such functions as closed loop of water supply pressure, circulated switching of pumps, dormancy and timing water supply to ensure average operation time of the water pumps and prolong the service life. The system has found wide application in waterworks, water supply in communities, heat supply stations and central air conditioning systems
