Controller for 6-axis parallel kinematics
High-performance controller for controlling hexapods (6-axis parallel kinematics). Supports a wide range of drive types as the controller only provides the control signals, whereas the motor drivers are located in the hexapod or in a separate driver box. The controller supports all currently available standard hexapods from PI and, in addition, customized parallel kinematics. In addition, the motor drivers for two further single axes can be controlled.
Functions
The position is entered in Cartesian coordinates from which the controller calculates the control of the kinematics. To simplify integration of the hexapod, the coordinate systems (Work, Tool) can be changed. The center of rotation can be freely defined in space. A data recorder can record operating data, e.g., motor control, velocity, position, or position error. The execution of macros and Python scripts on the controller enables standalone operation. An external switch, e.g., a motion stop button, can be used to enable/disable the 24 V output for the hexapod.
Interfaces
For use with the GCS 2.0 command set for PI positioning systems:
- TCP/IP for network-based control and maintenance
- RS-232 for serial connection to a PC
- Connector for optional manual control unit
Depending on version:
- High-resolution and extremely fast analog inputs that are ideal for Fast Alignment routines
- EtherCAT interface for connecting to a PLC device; requires an EtherCAT master with CoE protocol to be provided by the customer.
Extensive software support
For controlling via GCS-based interfaces. For example, PIMikroMove user software enables Fast Alignment routines to be depicted graphically. Extensive set of drivers, e.g., for use with C, C++, C#, NI LabVIEW, MATLAB and Python. PIHexapodEmulator for virtual startup and operation without hardware.
Scope of delivery
The scope of delivery includes the controller, a software package, and a power adapter for the power supply. It is recommended to order the hexapod mechanics and a suitable cable set together with the controller so that the components can be adapted to each other. A PLC master controller is not included in the scope of delivery.

Technology

Active Alignment
The need to align devices down to nanoscale accuracy is arising in many fields. Optical components such as the lenses or lens assemblies in small cameras, or even the CCD chip itself, need to be positioned with ever more precision.

Digital Motion Controllers
Digital technology opens up possibilities for improving performance in control engineering which do not exist with conventional analog technology.

Digital & Analog Interfaces
Fast USB or TCP/IP interfaces as well as RS-232 are the standard interfaces supported by modern digital controllers from PI. Furthermore, PI also provides digital or analog real-time capable interfaces.
