I need a better understanding of limit swtiches and servo motors than I'm getting from Wikipedia :)
Any website/textbook recommendations? (My background is physics.)

TIA!

Another approach is dig through the websites of major servo manufacturers such as Yaskawa, Siemens, Indramat (now, Rexroth-Bosch), etc. on the lookout for application manuals.

For Yaskawa, page through the Sigma II Servo System User Manual

Limit switches are often used as over-travel limits to disable the servo amp when something goes haywire with the motion controller, position feedback, and so on,.

With a simple DC servo system, a diode in parallel with the limit switch will prevent current and so motor torque once the limit is reached, while still permitting the motor to reverse back into the safe range.
