Description:Main technical feature: 1) Output frequency range: 0.00 ~ 600.00Hz 2) Speed control mode: sensor-less vector control (SVC), V/F control 3) Command channel mode: operator panel, terminal and remote communication 4) Frequency setting mode: digital keypad, analog input (current / voltage signals), remote communications, multi-step speed, PID closed loop 5) Starting torque: 150% / 0.5Hz (SVC) 6) Carrier frequency range: 1.0K ~ 16.0kHz 7) Speed control accuracy: ±0.5% max. speed (SVC) 8) Automatic voltage regulation (AVR): if the voltage of the power grid changes, the system can automatically maintain a constant output voltage 9) Torque limitation: the max. torque can be limited to protect the inverter reliably 10) Common DC bus: multiple inverters share the same DC bus and can implement automatic energy balance 11) Wobble frequency control: multiple triangular wave curves, meeting the personalized requirements of the textile industry 12) Multi-functional Quick / Jog key: can serve as a multi-functional key to meet the requirements of users for multiple applications 13) All input and output terminals are programable, for the convenience of users Reliable design: 1) Full series independent duct design: the heat sink supports installation inside or outside a cabinet (optional). The fans are convenient to replace and the inverter is simple to maintain, which greatly improves the reliability of the inverter during long-term operation in such different application environment as textile, printing and dyeing, chemical fiber, paper making, wire-drawing, and cement manufacturing 2) Wide power grid voltage design: when the input voltage of the power grid ranges from -15% to 15%, the inverter can run safely, and users does not need other handling 3) CHE series inverters above 7.5kW are configured with built-in DC reactors which improve output power factor and the efficiency and thermal stability of the integrated equipment, effectively eliminate the influence of the higher-order harmonic on the input side upon the inverter and reduce external interferences 4) Self safety test: upon power-on of the inverter, the system will conduct complete safety self-test of the software and hardware. The system implements safe clamping of the modification and setting of functional parameters, to prevent error settings of the functional parameters 5) Powerful protection: a) Provides users with more than 30 kinds of fault protection functions, and capable of all-around protection of inverters, motors and peripherals b) Provides the function of automatic reset upon a fault, to facilitate automatic removal of conventional faults c) With built-in lightening over-current protection unit, to efficiently improve protection from lightening induction
