New precision position control products from Physik Instrumente
12 April 2015
New from Physik Instrumente (PI) are a closed loop version of its N-4760 series linear actuators, plus a new voice coil drive controller that provides force, position and velocity control.
The N-472 is a new version of PI's PiezoMike linear actuator series that comes with integrated incremental encoder for closed-loop adjustment of mechanical and opto-mechanical components.
The N-472 keeps a position with long-term stability and is vibration-proof and shock-resistant. Like the N-470 open-loop version, the N 472 achieves its high holding force and resolution thanks to a piezomotor turning a fine pitch screw.
The incremental encoder measures the relative motion to a freely definable reference position. In combination with the E-871 motion controller the encoder resolution is up to <1 nm.
Even with an integrated position sensor, the N-472 PiezoMike linear actuator is a compact package and can be integrated in conventional mirror mounts or stages.
Meanwhile, the company's new digital motion controller for its V-273 and V-900KPIC industrial voice coil drives offer force, position and velocity control. The C-413 controllers also feature two motor channels and four sensor channels.
The servo update rate can be adjusted between 5 and 10kHz, and for control and configuration purposes, one real-time-capable SPI as well as a fast USB 2.0 interface are provided.
Digital inputs and outputs are standard features, while optional analogue inputs and outputs for sensors, commands or position feedback, can be provided.
