LS700/ LS700H Series High-performance Direct Torque Control Drive
【General-purpose Drive/Basic General-purpose Servo Drive】
LS700 series is a high-performance general-purpose drive that adopts real high-end magnetic flux vector control and direct torque control technology. It is mainly used to control and adjust the speed and torque of three-phase AC asynchronous motors and three-phase AC permanent magnet synchronous motors. It can easily achieve low-speed and high-torque output, with good torque response, precise speed control, and ultra-fast acceleration and deceleration. The product has rich and powerful functions, stable and reliable performance. It can be used to drive machine tools, cranes, ceramics, woodworking, glass, stone, food and other mechanical equipment, compressors, centrifuges, water treatment, heating fans, wire drawing, textile equipment and various automated production equipment.
1. Higher safety level design, compliant with CE, UL, CUL certification, RoHS instructions, and high-end users' equipments export certification requirements.Wide voltage input range according with the international standards, including three-phase 380to 480 V power grid demand, covering Europe,North America, India, etc.
2. Higher EMC designed, compliant with EU C3, C2 and other requirements. Automatical DPWM selection, effectively reduce harmonics.
3. Fast and accurate self-identification of motor parameters, and online self-adaptive adjustment of motor parameters. Industry-leading direct torque control (DTC) technology, open loop can achieve high-precision torque control, and closed loop can achieve position control.
4. Magnetic flux optimization technology (asynchronous motor), always adjust the magnetic flux in the best state, minimize motor loss, in order to achieve higher energy-saving effects, and reduce motor noise.
5. Stably and efficiently drive permanent magnet synchronous motors, including synchronous motors without speed sensors, which can realize direct drive on low-speed control industrial equipment.
6. The torque response is fast, the torque linearity is high, the dynamic response is fast, the speed control accuracy is high, no sensor is needed in 95% of the applications.
7. Low-frequency and high-torque output, ultra-smooth operation, speed sensorless control zero-speed 2 times of the torque, no mechanical brakes, smooth switching between driving and braking, help the equipment to operate safer and faster.
8. Integrate a variety of industry-specific parameters, built-in special parameter groups for hoisting machinery and curling control, which can easily cope with application industries such as lifting, drawing, rewinding, unwinding and constant tension.
9. Able to accelerate, decelerate and switch between forward and reverse running in the shortest time without mechanical constraints.
10. Automatic tracking start function, can quickly and intelligently identify the arbitrary speed and direction of the motor, and the start direction of the synchronous machine is locked and never reversed.
11. Abundant extended functions, supporting main communication bus functions and a variety of PG cards, standard built-in 485, CANOPEN communication, optional PROFIBUS-DP, ProfiNET, EtherCAT communication.
12. Standared powerful and easy-to-use assistant-type LCD keyboard with Chinese and English display, canidentify the drive information and control the drive more intuitively, conveniently and comprehensively. Support batch upload, download and save the parameters.
13. Long life design, independent air duct design, resisting a variety of harsh pollution, thermal reliability, whole machine temperature rise test, three anti-paint automatic spraying process, big amount of defective design, multi-protection function, to ensure high reliability of the inverter, long life.
