Motor Control

[draynor]

On an actuator i have an RVDT that provides a voltage of 0V at minimum stroke and 10V at maximum stroke. How do i use this voltage to shut off the 28V dc motor at either end of the stroke?? What should the circuit contain?

Please help! it'd be greatly appreciated.

Draynor,
Based on your last post, you may want to use the analog-digital route as this will offer the most flexibility. However, the comparators can also offer this flexibility but without all the possible features of a microcontroller or PLC based system (interfacing to displays, having user adjustments, etc).
For the comparators, if you wanted it to stop in the middle, I assume the voltage would be 10V. This would require the reference voltage to be changed to 10V, which can be done. There are adjustable voltage regulators that would simply require a variable resistor to be moved to change the output voltage. Now how you going to move the variable resistor? Could use a digital pot (variable resistor) and control this through some other software/hardware. Just some more thoughts to get your wheels a spinning, good luck.
