Glorious Guiding Precision – Geometric Efficiency
|
|
Geared up with high-precision crossed-roller bearings put in in a proprietary course of, these levels obtain glorious geometric efficiency: the 130mm variant, for instance, options 1.2µm straightness and flatness over the complete journey vary, together with pitch and yaw of solely 45 and 40µrad, respectively.
|
Excessive Velocity – Excessive Responsibility Cycle – 3 Journey Ranges
|
|
The V-574 linear motor levels are supplied with 60mm, 130mm, and 230mm journey vary.
|
|
Three-phase ironless, cog-free linear motors switch their pressure immediately and friction-free to the movement platform eliminating backlash and play that may happen with screw-driven levels. The V-574 levels obtain velocities as much as 1m/sec and 1g acceleration, whereas the brushless motors are maintenance-free, guaranteeing longevity in demanding 24/7 operations.
|
Alternative of Three Optical Encoders for Incremental and Absolute Measuring
|
|
Three encoder selections can be found, two sine/cosine encoders for conventional movement controllers and an absolute encoder with BiSS-C switch protocol. Absolutely the encoder achieves 1nm decision and transmits the present stage place to the controller instantly after energy up – no referencing required and no risk to lose encoder counts in electrically noisy environments.

What is the Advantage of Linear Motors?
|
|
Mechanically, the V-574 sequence options ironless non-cogging linear motors which permit for very clean movement, and a excessive dynamic velocity vary together with fast acceleration. They are perfect for functions the place excessive or extraordinarily fixed velocity is required, akin to in optics inspection, metrology, photonics, interferometry, and semiconductor take a look at tools. The frictionless, zero-wear motor drives are additionally well-liked in quick automation functions, the place reliability and most uptime are essential.

Controllers / Software program
|
|
A number of forms of controllers, together with a plethora of software program instruments, drivers and instance packages can be found from PI and its subsidiary ACS movement management.
