The C-866 motion controller was specially designed for closed-loop positioning systems with PILine® ultrasonic piezo linear drives. This compact unit contains not only servo-control and communications circuitry, but also the drive electronics.
Spezialized Servo Algorithms for Ultrasonic Motors
The C-866 uses a highly specialized DSP (Digital Signal Processor) to handle the PID servo-control algorithm as well as other system functions. Because of the motion properties typical for ultrasonic piezomotors, the contoller has a number of special features, including dynamic control parameter adaptation. The high-bandwidth encoder input with a limit frequency of 35 MHz supports the high velocities of ultrasonic piezomotor stages, even at high resolution.
Integrated Drivers for Piezomotors
To reduce the number of components in the PILine® positioning system, the piezomotor drive electronics has been integrated in the controller. Various versions of the controller are available, depending on the piezomotor used.
The C-866.161 version, for example, contains the drive electronics for the P-661 motor (page see link f) , which is used in the M-663 (page see link f) micro linear stage.
To assure the best possible system performance in terms of force, velocity up to several 100 mm/s and settling times of a few tens of milliseconds, the integrated drive electronics is fine-tuned to the connected actuator / stage at the factory.
Software / Programming
In addition to the user software for setup, system optimization and operation, comprehensive LabViewTM and DLL libraries are provided.
Communication with the C-866 is provided either through the RS-232 or the USB interface. For manual control, the unit can be operated with a joystick on the host PC.
The PIMikroMove® user software provides the PITuning-Tool for system performance optimization. Graphic displays show the system"s behaviour and facilitate parameter setting.
Optionally, the C-843.ATS Auto-Tuning software is available; it determines the ideal settings automatically.
PI General Command Set (GCS)
The comprehensive command structure is based on the PI General Command Set (GCS). With GCS the development of
custom application programs is simplified, because the commands for all supported devices are identical in syntax and function. PI controllers for nanopositioning systems, for piezomotors and servo or stepper motors can be commanded with GCS.
Advantages of PILine® Micropositioning Systems
The ultrasonic piezoceramic drives used in PILine® micropositioners have a number of advantages over classical drives:
- Higher Accelerations, up to 10 g
- Speeds up to 500 mm/s
- Small Form Factor
- Self-Locking When Powered Down
- No Shafts, Gears or Other Rotating Parts
- Non-Magnetic and Vacuum Compatible Drive Principle
