Advanced Control System for iBTF with Mitsubishi Servo Motors and Remote Software Interface

The iBTF system utilizes three independent Mitsubishi servo motors for precise control of grating positions and light path alignment. Each motor offers a high resolution of 262,144 pulses per revolution, equating to 7,281 pulses per degree. The user-friendly iBTF control software allows for seamless connection to a PLC and enables remote operation via TCP-IP, ensuring both accuracy and convenience. Safety measures are being developed to prevent collisions between gratings while maintaining an accurate light axis. Suggestions for further security enhancements are encouraged.

  1. iBTF Control For iBTF control, we have 3 independent motors. TheFirstmotorsrotatestheonegrating Andthethird motor (behindtheinstrument) makethe light beansparallel. Thesecond do thesame, makingbothparallel. Whatkindofmotors is this??? It’s a Mitsubishi servo motor with 1/20 reduction gear. These motors have 262,144 pulses/revolution giving 7,281pulses/degree!

  2. iBTF Software Control It’s a verysimple interface software, betweentheuser (orother software) andthemotors Makeconectionwiththe PLC Theotherway to use this software, is controlling it remotlyon TCP-IP connection.

  3. Risk of colisions between the grating Butweneed more securitystages, becausethemotorsdriverscanbroken (for exemple) orbecomeuncontrolled. This is a open questionyet. Wehaveoneidea: As a 1st level interlock, the software calculates the distance between both gratings to avoid collisions. This grating translates to keep the light-path on axis. There is a risk of collision between the gratings Put switch in the corners HINTS ARE WELCOME!!!
