Powerful and Economical: High-Load Linear Stage Series for a Fast and Highly Repeatable Positioning in Industrial Precision Automation

PI (Physik Instrumente) expands its portfolio for industrial precision automation with the new V-855 und V-857 high-load linear stage series. With these, PI now offers cost-efficient positioning systems for processing and inspection tasks that require high speed and repeatability over long travel ranges. These series are suitable, among others, for applications in electronics manufacturing and micro assembly, for testing sensors, or for use in inkjet printing processes.

The linear stages are specifically designed for industrial applications with high operating cycles over long travel ranges: 3-phase linear motors with recirculating ball bearing guides make a constant load to 1000 N, accelerations to 5m/s², and velocities to 5000 mm/s possible.

High-resolution linear encoders also ensure a high tracking accuracy, minimum tracking errors, and short settling times. The calibrated bidirectional repeatability of the linear stages is ±0.5 µm.

A Variety of Possible Combinations and a Simple Machine Integration

For multi-axis applications, the linear stages can easily be combined to gantry setups. The axes can be assembled individually thanks to the optionally available motion platform and the triple M6 hole pattern. Because of the slim design of 132 mm maximum width, they can be integrated in a space-saving manner into compact machine assemblies.

In addition, the linear motor stages are designed in such a way that they can be configured, in combination with additional linear axes to become powerful gantry or split-bride systems.

Industry-Compliant Controls

For the control of the V-855 and V-857 linear stages, PI offers the G-901 19” rack electronics solution, which combines an ACS Motion Controller and drivers for up to four axes as well as an integrated "Safe-Torque-Off" (STO) module. Alternatively, modular ACS drivers, such as UDMpa, combined with the powerful ACS Motion Controller or third-party control solutions can be used.
