High-Speed,Closed-Loop Controller/Driver for PILine

Ultrasonic Piezo Linear motors

Ordering Information C-865.161 Piezomotor Controller with Drive Electronics, 1 Channel, for PILine ® Systems with P-661 Motors ® C-865.165 Stagesand Motors
Piezomotor Controller with Drive Electronics, 1 Channel, for PILine ® Easy-to-Use Software /General Command Set (GCS) To assure the best possiblesystem performance, the inte- grated drive electronics is fine-tuned to the connected stageat 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.
M-665 Translation Stages For ease of operation, the C-865 is compatible with the PIGeneral Command Set, de- signed to allow flexible combi- nations with other PI motion controllers (fiber aligners, step- per-motor controllers andpiezo controllers for ultra-fast,sub-nanometer motion con- trol). For more information on GCS, see p. 9-28. Communication/Programming Advantages of PILine Speeds to 500 mm/s and more Programming the C-865 is sim-plified by comprehensive soft- ware support, including Lab- View™ drivers and DLLs. Allunits are equipped with bothUSB and RS-232 Interfaces for communication with the host PC. In addition to the easy pro- gramming with GCS com- mands, direct INDUSTRIAL DSP register access with low-level com-mands is also possible.

C-865 with a PILine ® M-663 miniature translation stage. Notes To reduce the number of com-ponents in the system, the pie- zomotor drive electronics has been integrated in the C-865 controller. Models C-865.161 and C-865.165 are optimized forpositioners with P-661 motorsand M-665 stages, respec- tively. Optimized for PILine
® Piezo Linear Motors High-Speed Encoder Input: 35 MHz PID Servo Algorithm with Dynamic Parameter Switching Integrated Piezomotor Drive Electronics S-Curve Profile Generator Industrial limit switch Control 3 TTL Inputs, 3 TTL Outputs Analog Input Specialized PID Servo controller Comprehensive High-Level Language Command Set Extensive Software Support, GCS Compatible (see p. 9-28) The C-865 uses a highly spe-cialized DSP (Digital SignalProcessor) to handle the PID servo control algorithm, which has a wide range of options for controlling and programming acceleration, velocity or set-tling as well as other systemfunctions. Because of the static frictionwhich is typical for piezomo- tors, the controller has a num- ber of special features, in-cluding dynamic parameterswitching for an optimized high-speed motion and settling behavior. The high-bandwidth encoder input with a limit fre- quency of 35 MHz has amplereserves for the high speeds characteristic of piezo linear motors. 1 Mbit RAM for Real-Time Tracing The C-865 controller was spe-cially designed for the newestgeneration of PILine
® piezo lin-ear motors and stages. Thiscompact unit contains not onlyservo-control and communica- tions circuitry, but also the drive electronics for the piezo ceramic motors.
