New from LG Motion – DC motor control by Polaris

21 July 2016

Polaris is an advanced off-the-shelf motion control platform that demonstrates speed, precision and programming flexibility.

Motion control applications can be realised by using Polaris hardware components which include the controller, drives, digital I/O, analogue I/O, other Polaris devices and extensive motion control software which includes function libraries, executables and graphical user interfaces.

The advanced motion control platform demonstrates speed, precision and programming flexibility. Polaris has the highest rates and widest dynamic range of most motion control system available. Polaris consists of the Polaris motion controller, Polaris amplifier drives and Mercury, the Gbit/s real-time network that provides communication between the controller and the drives.

Exacting application example

A leading UK research institute have been developing a state of the art instrument that required the very best control. The instrument does a step scan moving in 0.1 micron and then holding for a second to collect data, then repeating the process. The customer needed a controller with the least “jitter” at standstill.

A Polaris system consisting of an interpolator with integral encoder compensation and a 3 phase linear drive which can achieve sub-nanometre servo performance was recommended and the target performance was immediately achieved and exceeded.

Polaris is an advanced off-the-shelf platform for the control and synchronisation of servo motors, Galvos, lasers and other high performance devices. Polaris delivers uncompromised speed and precision and was designed for:

• Very high precision diamond tool machining
• Precision and ultra-precision grinding
• Laser micro machining
• Mills and Lathes with sub-micron tolerance requirements
• CNC machines with integrated tool and part measurement requirements

Using Polaris will offer you:

• Increased system precision 
• Higher throughput 
• Faster software development
• Access to develop custom features
