Positional Controller


An embedded controller unit is used for each axis. The positioner’s axes are controlled via a single RS232 connection. The positioner can be controlled most simply by a computer terminal (not supplied) sending single commands for variable speed, sector scan, etc. Alternatively, we can provide a user-friendly generic graphical user interface and controller application based on a Windows 2000/XP environment for more convenient control. For other operating systems please contact us and we will be happy to discuss your requirements.
