The new 2-axis C-867 piezo motor controller is especially designed for closed-loop micropositioning systems equipped with piezo linear motor drives. It can be operated from a host PC either via a USB port or an RS-232 interface. Alternatively, stand-alone operation is possible by joystick or via preprogrammed macro commands.
Why Ultrasonic Ceramic Motors?
Ultrasonic ceramic motors are non-magnetic and self locking by nature. They provide significantly better position stability than conventional motor / leadscrew drives or magnetic linear motors. A paper documenting long term stability of different positioning stage principles is available here: http://www.bentham.org/cpb/sample/cpb10-5/0008G%5B1%5D.pdf
Faster Settling with Dynamic Control Parameter Adaption
The C-867’s highly specialized DSP handles all of the motion properties typical for ultrasonic piezomotors, such as dynamic control parameter adaption. Optimized settling behavior of the mechanics within 10s of milliseconds is achieved by automatically switching between gainsets for dynamic and static operation.
Highest Stability by Automatic Frequency Control
Changes in the mechanical properties of the ceramic motor due to temperature or load changes are automatically compensated for by a control loop which adjusts the operating frequency of the driving voltage. This leads to the highest constancy in motor force, velocity and closed-loop stability.
