Starvert iH

Space vector PWM technology

The Space vector technology is being adopted in all LG drives. It features outstanding performance in its control characteristics. It has low total harmonic distortion, low current ripple, low torque ripple, low motor temperature rise, and better voltage utilization. It is a basic control platform of the iH. The advantages of Space vector PWM technology are being provided in many applications. Better Efficiency (Low Iron Loss in Motor)Low Motor Heat (Extended Motor)High Voltage Utilization (15.9%)Stable & Smooth OperationHigh and Stable Torque
Low Total Harmonic DistortionLow Torque RippleLow Current Ripple

Convenient and Various Communication InterfaceBuilt-in PI control

The iH can be operated with communication interface such as RS485, ModBus-RTU, DeviceNet, Profibus, and F-Net, in order to be operated in various circumstances. Driveview 2.0 software is a Window based tool that provides convenience of monitoring and controlling to user. The Driveview 2.0 features a graph monitor, keypad professional emulator, parameter editor, and text monitor, to help user`s monitoring and controlling of drive. It is applicable for all LG drives. It is valuable in process control. The built-in PI controller controls flow, temperature, pressure, etc. through the proportional and integral calculus between the feedback value and reference value in closed loop.

CT / VT Dual Ratings

The iH features dual ratings in order to be used in both of constant torque and variable torque load conditions. User can pick the most suitable drive through dual ratings for various load conditions. In that way, user can be prevented from using an overpowered drive. 03
