Precision motion control systems specialist, PI (Physik Instrumente), just launched the C-887.52, a hexapod controller for parallel kinematics precision positioners. With a real-time operating system, 6-D vector motion control, a high-level command set, and optional collision avoidance software, this compact bench-top solution is designed to extract the maximum performance and precision out of hexapod parallel positioning systems.
Hexapod control with 6+2 channels
The goal of the C-887.52 is to facilitate the control of the hexapod 6-axis parallel positioner. The user enters commands in Cartesian coordinates and the controller turns it into vectorized motion. Fast servo update rates (10kHz) and error compensation support path accuracy and dynamic performance. The user can also specify the center of rotation with one single command.
A data recorder captures valuable data, such as velocity, position, and position error. In addition to controlling the six parallel kinematics axes of the hexapod, outputs for two more servo motors are included.
Software/communication
The controller comes with software programs for test, configuration and simulation. Drivers and program examples for positioning and alignment are also included. Start up and operation is supported by the PIMikroMove user software, providing a powerful graphical user interface that also displays scan routines. Communication is via USB and TCP/IP, digital and analog I/O. The built-in macro command language simplifies programming of repetitive tasks and also makes standalone operation possible as does the optional manual control unit.
Custom designs
Custom controller designs are available, e.g., for use at high altitudes, for applications requiring increased safety using redundant systems and for closed-loop alignment application using optical feedback.
