Product Details Supplier Info More products

LG Motion is now offering motion control technology from Precision Microdynamics (PMDI), a machinery manufacturer specialising in high-speed distributed motion control, data transfer and acquisition.

PMDI’s newly released Polaris is a complete motion and machine control system than runs on the company’s own real-time Gbit/s Mercury network.

With multi-axis motion controllers, servo amplifiers for brushed and brushless motors and high-bandwidth galvanometers and voice coil actuators, plus digital and analogue I/O modules, Polaris is said to complement LG Motion’s range of positioning mechanics to enable customised automated sub-systems for applications across industry and research.

The Polaris is also targeted at system integrators and original equipment manufacturers (OEMs) who require the flexibility of a distributed motion and machine control platform for their own automated machinery.

The Gbps Ethernet-based Mercury communication (patent pending) is a high-speed real-time network offering the synchronisation of data acquisition and control in all amplifier and I/O modules to within 10ns and motion capability to 124 axes.

For even faster timing co-ordination, the optional Pulsar module further reduces the sampling jitter to achieve sub-nanosecond synchronisation.

With the servo loop performed in the amplifier, enabling rates of up to 200kHz, advanced system performance features include advanced motion path planning, cubic splines, PVT profiles and jerk limitation.

Both the motion controller and the amplifier feature full 64-bit double-floating-point calculations for high levels of positioning accuracy, fast servo feedback rates and submicron resolution for improved form and finish combined with high speed and acceleration controls that enable faster production throughput.

PMDI’s Polaris motion control system includes multi-threaded customisable software that allows users to create their own scripts and user-defined G-Codes.

A powerful graphical user interface is included that runs on Windows systems.

The range is fully supported with setup, status, tuning, tutorials and help wizards that are designed to enable fast and straightforward system commissioning and programming.

LG Motion

LG Motion is one of the UK’s leading designers and manufacturers of drive and control systems.
The product range is extensive and often an amalgam of motion control components. In simple terms however LG Motion design and develop systems that make things go in and out, up and down and round and round!
