Specifications

  • 160/260/360 mm travel
  • 1 nm absolute encoder resolution
  • 80 nm bidirectional repeatability
  • Straightness/flatness to 1 µm
  • 500 mm/sec max. velocity
  • 1 g acceleration
  • 140 N push/pull force

With 80 nm bidirectional repeatability, 1 g acceleration and 500 mm/s velocity, the V-573 family combines precision and speed for demanding production environments. Designed for XY configurations, the stages integrate seamlessly with PI’s ACS-based EtherCAT motion controllers, leveraging advanced algorithms for optimal system performance.

The advanced stage design provides for excellent straightness and flatness values as low as 1 µm. Crossed roller bearings ensure high stiffness, smooth running and extended lifetime. Their line-contact design minimizes friction, improves accuracy and supports higher loads, with an anti-creep mechanism for enhanced reliability.

Driven by non-cogging, three- phase direct-drive linear motors, the stages deliver maintenance-free performance with smooth motion at high velocities and accelerations. Direct force transmission together with direct-measuring linear encoders eliminates backlash and play, while improving accuracy and bidirectional repeatability.

The V-573 is available with incremental or absolute encoders. Absolute encoder models offer 1 nm resolution and immediate position feedback on power-up, eliminating referencing moves for efficient, safe startup.
