The C-865 controller was specially designed for the newest generation of PILine® piezo linear motors and stages. This compact unit contains not only servo-control and communications circuitry, but also the drive electronics for the piezoceramic motors.
Specialized PID Servo-Controller
The C-865 uses a highly specialized DSP (Digital Signal Processor) to handle the PID servo-control algorithm, which has a wide range of options for controlling and programming acceleration, velocity or settling as well as other system functions.
Because of the static friction which is typical for piezomotors, the controller has a number of special features, including dynamic parameter switching for an optimized high-speed motion and settling behavior. The high-bandwidth encoder input with a limit frequency of 35 MHz has ample reserves for the high speeds characteristic of piezo linear motors.
Integrated Drive Electronics, Optimized for PILine® Stages and Motors
To assure the best possible system performance, the integrated drive electronics is fine-tuned to the connected stage at the factory. M-663 miniature-stages can then, for example, achieve speeds up to 500 mm/s and more with a resolution of 0.1 µm and settling times of less than 10 ms.
Easy-to-Use Software / General Command Set (GCS)
For ease of operation, the C-865 is compatible with the PI General Command Set, designed to allow flexible combinations with other PI motion controllers (fiber aligners, stepper-motor controllers and piezo controllers for ultra-fast, sub-nanometer motion control). For more information on GCS, see p. see link.
Communication/Programming
Programming the C-865 is simplified by comprehensive software support, including LabView™ drivers and DLLs. All units are equipped with both USB and RS-232 Interfaces for communication with the host PC. In addition to the easy programming with GCS commands, direct DSP register access with low-level commands is also possible.
Advantages of PILine® Micropositioning Systems
The piezoceramic drives used in PILine® devices have a number of advantages over classical drives:
- Higher accelerations, up to 20 g
- Speeds to 500 mm/s and more
- Small form factor
- Self-locking at rest
- No shafts, gears or other rotating parts

Notes
To reduce the number of components in the system, the piezomotor drive electronics has been integrated in the C-865 controller. Models C-865.161 and C-865.165 are optimized for positioners with P-661 motors and M-665 stages, respectively.
