(PresseBox) - From genome sequencing through multiphoton fluorescence microscopy, deep tissue inspection, laser materials processing, and wafer inspection to magnetic tweezers in research ? vertical positioning systems with large travel range, high dynamics and precision are required in numerous applications in microscopy and industry. With the new V?308 voice coil PIFOC, PI now offers a magnetic direct drive based solution that unites all these requirements.

The core element of the V-308 PIFOC is a single axis slider with high-precision lateral crossed roller guides placed on the base body. The slider is driven by a centered PIMag

The high-resolution optical PIOne linear encoder is used to achieve the high precision requested. A minimum incremental motion of 10

Magnetic Weight Force Compensation

A special feature of the new V-308 PIFOC is the magnetic weight force compensation. This ensures a levitation of the slider and mounted load without power supply and it so prevents an uncontrolled crash in case of a power failure or when switching off the controller. For a flexible use of the axis ? when switching the objective, for example ? the user can adjust the counteracting force and compensate an overall load (objective and holder) of up to 1 kg. Because of this, the axis acts as a horizontal axis even when being used vertically.

Easy Integration Thanks to a Compact Design and Versatile Accessories

With dimensions of 87 x 77 x 30 mm (H/W/D), the drive is very compact. An adapter plate ensures mounting on an optical bench or plate, with a metric or imperial hole pattern. Two different objective holders (for vertical or horizontal mounting) as well as a set of adapter rings for different diameter objectives, up to size M32 x 0.75, are available.

As a standard, the V-308 PIFOC is offered with the specially developed C-414 controller. Alternatively, the axis can be operated with ACS controllers with built-in EtherCAT functionality. Users can actively control servo control parameters ("gain scheduling"), which in addition with other ACS features such as ServoBoost, can further enhance the performance.
