!l1ARdYY I2DX'R Precision motion over several millimeters with high position resolution places great demands on drive hardware. Not only do dynamic performance and generated force requirements have to be considered for each application, but also available space.

Three Systems: One Solution for Every Application PI has been providing two types of piezo linear motors for many years. The new and cost-effective NEXACT piezo linear drives now fill the niche between the fast, flat PILine® drives (50 nm resolution, up to 800 mm/sec) and the heavy-duty, ultra-precise NEXLINE drives (up to 600 N, sub-nanometer resolution). The outstanding features of the NEXACT OEM stepping drives include virtually unlimited travel range, very high positioning resolution in the sub-nanometer range and highly compact design—the N-310 is only 25 x 25 x 8 mm (1" x 1" x 5/16")— not to mention the vacuum-compatible and non-magnetic operating principle.

j0B;\e(G NEXACT technology uses the PiezoWalk drive principle that combines two operating modes: step motion for unlimited travel range and a highly-dynamic linear (analog) mode for sub-nanometer resolution within a step. The runner of the linear drive is moved forward or backward by piezoelectric actuators, which alternately clamp and drive it. In the ultra-high-resolution linear mode, all the piezo actuators clamp and drive the runner together, without stepping. NEXACT differs from NEXLINE in its smaller size, lower force generation and lower operating voltage of less than 40 V.

Micro or Nano: The Electronics Make the Difference For ultra-precision nanopositioning applications, the highly sophisticated E-860-series NEXACT driver/controller series supports both stepping and linear modes in open- and closed-loop operation.Ntt.[2`$o%qWy W,M
