Performance Automation: New Linear Motor Stages for High Load / Precision Industrial Applications and New EtherCat Motion Controllers

PI introduces a new motion controller and precision linear stage family geared towards precision industrial automation applications. The V-817 linear stages, engineered for highly dynamic and precise motion, boast a load capacity of 600 N, travel ranges from 8” (204 mm) to 32” (813 mm), and velocities to 3000 mm/sec.

Driven by 3-phase linear motors and guided by robust recirculating ball bearing guides, the low-profile design of only 63 mm minimizes moving mass and tilting errors. An integrated linear encoder provides <1 nm resolution and when operated with PI’s industrial motion controllers, the stages achieve 10 nm minimum incremental motion, 1 µm bidirectional repeatability, and 2.5 µm accuracy.

XY Stage Configurations

Stages can be combined for XY motion thanks to an available platform with a triple M6 hole pattern. The V-817 is only 63 mm high (without the platform), making it easy to integrate into compact machine assemblies.

EtherCat Compatible Motion Controller Family

The stages are compatible with the new G-901 industrial motion controller family. These controllers are based on ACS hardware with EtherCat connectivity, providing up to 1500 W output per axis. Many advanced control features, such as Servoboost, NanoPWM and special algorithms for Gantry Control, laser triggering and high speed contouring, are available and improve the throughput and performance in applications from Laser Machining to 3D Printing.
