Motion Control & Drives
Ana-Digi Systems is offering a range of AC drives from LG Industrial Systems - a manufacturer specialising in AC drives and PLCs. The iS5 and the iH are two variable frequency drives from the Starvert range, which are intended for applications rated from 0,75 to 22 kW and 30 to 220 kW, respectively.
Starvert iH
The iS5 offers up to 22 kW when running off three-phase AC supplies of 200 to 230 V or 380 to 460 V. The enclosure is rated IP00 ~ IP20. The IGBT inverter makes use of pulse width modulation with sensorless vector control. An intelligent accelerate/decelerate function prevents unnecessary tripping. This model also features additional I/O boards that are easily mounted onto the connection terminal of the motherboard, with each I/O standardised for specific requirements. This makes the iS5 extendable when there is any need for additional I/O, etc.
Starvert iS5
The iH is designed for three-phase operation, producing 30 to 55 kW when running from 200 to 230 V, and 30 to 220 kW when operating from 380 to 460 V supply. The inverter, like the iS5, is an IGBT stage that is pulse-width modulated. Control is performed by a high-speed digital signal processor implementing a Volts/Hertz control method, with space vector PWM technology.
LG Industrials space vector PWM technology is being adopted in all LG drives. Said to feature outstanding performance in its control characteristics, it produces little total harmonic distortion, low current ripple low motor temperature rise and better voltage utilisation. Advantages for the end user include higher efficiencies, smoother and more stable operation and higher torque without instability. Options include Dynamic braking units and a communications board offering: RS485, F-Net, ModBus-RTU, DeviceNet and Profibus. The Driveview 2.0 operating software is Windows based.
Suitable applications include: Fan/blower, water/wastewater pump, conveyor, parking system, material handling, industrial washing machines and packaging machines.

Control system for deep antenna
Rockwell Automation
Motion Control & Drives
When a major university in South Korea set out to build a 21-metre deep space antenna, the researchers needed a control system that could track celestial objects with pinpoint accuracy, a level of precision they thought was out of reach. By partnering with Rockwell Automation, they discovered that the right technology and support could turn their vision into reality.
