E-870.10: Single-channel driver for PIShift piezo inertia drives (to be plugged in or soldered)

With the E-870 series for the piezo-based PIShift inertia drives, PI (Physik Instrumente) offers a series of drive electronics at various integration levels. Whether as OEM board, as a variant for 4-channel serial control, or as bench-top device in a case: The E-870 combines low costs with an extraordinary ease of operation. The driver can be configured and operated via a USB interface. Software drivers for Windows and LabVIEW facilitate the integration in system environments.

The device can also be configured and operated using hardware settings. Various operating modes allow the flexible use of the drive electronics, e.g., by means of an analog input for velocity control or TTL inputs for triggered operation. Digital outputs can be used to monitor the operating status or the temperature. PI offers the drive electronics also on a separate carrier board with easily accessible electrical contacts using sockets and terminal strips. Two push buttons on the board for forward and backward motion allow a quick start-up of the driver. With the current version, serial operation of up to 4 channels is possible through demultiplexing.

In the future, PI will also offer a driver in a desktop case as well as a motion controller for position-controlled operation of the PIShift drives.
The PIShift uses the stick-slip effect with a holding force of 10 N and a typical feed of approximately 300 nanometers per motion cycle in full step mode. With an operating frequency above 20 kHz, PIShift drives reach velocities of more than 5 mm/s. At this frequency the operation of the drive is inaudible to the human ear.

Well-known for the high quality of its products, PI has been one of the leading players in the global market for precision positioning technology for many years. PI has been developing and manufacturing standard and OEM products with piezo or motor drives for 40 years now. With four German factories and ten subsidiaries and sales offices abroad, the PI group is represented internationally.

New piezo nanopositioning system: versatile, fast and compact with large clear a …
Large clear aperture, high control dynamics, fast settling times and compact dimensions: PI launches a new product line of linear nanopositioning systems for a broad range of applications. The P-630 stages are perfectly suited, e.g. for use in sensor heads or precision motion of objects in optical and tactile metrology as well as for microstructuring. With travel ranges up to 80 µm and a direct piezo actuator drive, the compact positioning
2 mm Travel Range - 20 Milliseconds Settling Time: New Objective Scanner with Pi …
New microscopy methods, such as two-photon microscopy, make it possible to record 3D stacks with up to 1 mm depth in biological samples. For this they require high-performance drives for positioning the objectives. PI (Physik Instrumente) now developed the new N-725 PIFOC® objective scanner with piezo stepping drives especially for position-ing microscopy objectives. The N-725 provides travel ranges of up to 2 mm along the optical axis. At the same time
New Version of M-663 Micropositioning Stage: Benefits of PILine® Drive Technolo …
Cost-effective with 2 µm step size. PI (Physik Instrumente) completes its product line of high-velocity M-663 micropositioning stages. The new linear stage version M-663.5U is especially suited for positioning tasks in automation where a resolution of 0.6 µm and a step size of 2 µm are sufficient. The integrated PILine® linear motor provides push forces to 5 N and a maximum velocity of up to 250 mm/s over a 18 mm
Small Size and High Resolution: New Miniature Stage is Only 24 mm Wide at a Reso …
Physik Instrumente (PI) has introduced the new LPS-24 series. At only 24 × 33 × 20 mm³, these new miniature positioning stages provide a travel range of 15 mm with nanometer-precision resolution. The LPS-24 stages fulfil important requirements for the positioning of optical or mechanical components or for the adjustment and manipulation of samples in application environments with a confined space. For the LPS-24 series, PI uses NEXACT® piezo stepping drives. These
