The new C-843 PCI motion controller card drives up to 4 axes of micropositioning equipment. Because there is no need for external servo- amplifiers, this new card is a very cost-effective, easy-to-set-up solution.
On-Board Servo Amplifiers
Unlike other PCI controller cards, the new C-843 comes with on-board, low-noise linear amplifiers for the small DC motors used in most compact micropositioning stages and actuators.
In addition, PWM outputs are available to drive more powerful equipment (all direct-drive translation and rotation stages from PI feature the integrated ActiveDrive™ PWM amplifiers, and also connect to the C-843 with no external power amplifiers).
The PWM mode and linear amplifier mode can be programmed individually for each of the 4 (or 2) channels.
High-Performance PID Control
The C-843 employs a fast DSP (digital signal processor) providing high-performance PID motion control with many options for trajectory generation and filter settings for superior positioning and tracking accuracy. Position, velocity, acceleration and several other motion parameters can be programmed individually for each axis on-the-fly. High-bandwidth counters (5 MHz) support differential encoder feedback (incremental rotary encoders or linear scales) for fast and accurate positioning.
I/O for Flexible Automation
In addition to 3 TTL inputs per channel for limit and reference signals, 16 more I/O lines are available for flexible automation tasks (trigger functions, etc.). The C-843 also features motor-brake output lines (e.g. for M-531.DDB stages).
High-Speed Tracing
The integrated 64 kiloword trace memory allows online tracing of up to four independent system variables (positions, velocities, internal register contents, etc.) at integer multiples of the servo-loop time.
Easy-to-Use Software / Programming
For ease of operation, the C-843 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).
Communications to/from the board consist of packet-based messages passed via memory access. An interrupt line is provided so that the chipset can signal the PC when special conditions arise, such as reception of an encoder index pulse.
In addition to an ample array of software tools, such as LabVIEW™ drivers and DLL libraries, the C-843 comes with the PISmartMove operating software providing all functions for single command execution as well as macro command facilities.
To facilitate setup, any supported PI MicroPositioning system just needs to be selected from a PISmartMove menu and all default control parameters will be set.
For system integration, the C-843 offers full access to the motion DSP via a PCI bridge.
C-843.21P and C-841.41P for Ultrasonic Piezomotors
Ultrasonic piezomotors as used in PIline™ closed-loop MicroPositioning stages exhibit different behavoir from classical DC motors. C-843.21P, C-843.41P and the C-843.PM upgrade thus contain additional software tools to optimize the operation of PIline™ piezo motor stages such as the compact M-663 (see link) with the C-843 controller boards. The C-843.21P / C-843.41 allow both the operation of PIline™ stages and MicroPositioners with DC-motor.

C-843.40 DC-motor controller board with M-110.DG linear stage, M-235.5DG heavy duty linear actuator, M-511.DD direct drive translation stage and M-501.1DG vertical stage. No external amplifier is required to drive any of these or other PI stages. Small motors are driven through the C-843's onboard linear amplifiers, direct-drive PI stages (e.g. M-511.DD) employ ActiveDrive™ controlled off the C-843's PWM outputs.
PI General Command Set permits consistent programming of a wide variety of PI motion systems.
PISmartMove software is easy to use.
To facilitate setup, any supported PI MicroPositioning stage just needs to be selected from a PISmartMove menu and all default control parameters will be set.
