Program editor software extends CAD support
Active Editor Pro dramatically increases the number of users who can benefit from its simple programming style, by adding support for CAD models from a large variety of CAD formats.
The focus for position feedback systems will be a robust, high accuracy linear encoder, a range of high-performance high-vacuum encoders, plus demonstrations of improvements in speed, resolution and reliability to the firm's standard optical encoder lines of industrialised RG2 and RG4 linear encoders.
Renishaw will exhibit optical and magnetic technologies for precision positioning.
The optical encoders were created to bring high precision, speed and reliability to demanding environments and tough industrial applications.

Magnetic encoders boost dragster speed
Two RM22 compact high-speed rotary magnetic encoders clutch speed and monitor the position of the engine's crankshaft, helping to take the bike reach extremely high speeds.
Metal scales avoid the fragility of glass encoders, while non-contact read heads and filtering optics avoid the bulkiness, hysteresis and wear of traditional industrial encoders.
The Signum rotary and linear encoders apply that same formula of ruggedness and precision to fine-pitch systems too delicate for many industrial roles.
The Signum encoder range offers high accuracy, resolution and repeatability with high speed, high operating temperatures, low cyclic error and In-Trac optical reference mark, which remains phased over the entire speed and temperature specification.
The system uses intelligent signal processing and the cyclic error is typically less than +/-40nm.
Signum software enables set-up and real-time system diagnostics via a PC's USB port.
The Signum RESM annular encoder is a one-piece stainless steel ring with 20um scale marked directly on the periphery.
It has the In-Trac optical reference mark, which repeats, regardless of direction, at operational speeds of over 4500rev/min (52mm diameter) and up to 85C.
The Sifnum RELM linear encoder comprises the SR read head, Si interface and 20um RELM scale, which is offered in defined lengths.
Initially available in Invar, which provides a thermal expansion of 1.4um/m/C, the RELM scale comes with a choice of In-Trac reference mark positions and dual optical limits.
With the 20um spars, the RELM provides accuracy to +/-1um and resolution to 20nm.
Show visitors will see that the magnetic encoders are available in component, modular and packaged shaft-style models.
The RM magnetic encoders offer up to 4096-count positioning resolution, accuracy to 0.4um, and operating speeds to over 9000rev/min.
The non-contact magnetic design eliminates seals, bearings and moving parts for lifetime reliability. Request free introductory details about products from Renishaw ...
