LG Motion to supply motion controls to Anorad

17 February 2012

LG Motion has been appointed by Anorad to provide motion controls for its wide range of high precision positioning stages and gantry systems. The arrangement will marry Anorad CHPS series direct drive linear stages, its Hercules series gantry stages and engineered to order positioning mechanics with LG Motion's range of motion controls and expertise – focussing on high speed distributed motion controls, advanced servo amplifiers, networked data transfer and acquisition controls from PMDi.

Anorad (a division of Rockwell Automation) has expertise in high speed linear servomotor based systems using both iron-cored and iron-less direct drive technologies.  The company is particularly well established in high end applications in semiconductor fabrication and packaging, flat panel manufacture, data storage and laser micromachining.

Typical specifications for high speed test and inspection positioning systems include velocity to 5 m/s, acceleration to 5 m/s2, and accuracy better than +/- 3 microns over travels of 25mm. Highly configurable CHPS series linear stages offer positioning resolution to 0.1 microns and travel range to 2 m, and are available with a wide choice of customisation options.

The PMDi range, exclusively represented in the UK by LG Motion, is centred on the Polaris motion and machine control system than runs on the company's own real-time Gbit/s Mercury network. Comprising multi-axis motion controllers, servo amplifiers plus digital and analogue I/O modules, Polaris is perfectly suited to high speed and high precision positioning with the fastest real-time network available on the market today. 

With a motion capability to 124 axes, the network can synchronise motion, I/O and data acquisition of all amplifier and other modules to within 10 nanoseconds - with the possibility of even faster timing coordination with the optional Pulsar module which reduces the sampling jitter to achieve sub-nanosecond synchronisation. Servo amplifier technologies are available for linear and rotary brushless servo, brushed motors, galvo and voice-coil actuators.

The combination of Anorad high precision positioning stages and PMDi motion and machine controls will enable high throughput motion sub systems for production, inspection and research based applications with LG Motion using its in-house design and manufacture capability to bring these products together as the enabling technology motion systems for its customers.
