Programming Servo Motors

[gpetilli]

Assuming you are using the Jaguar speed controller in servo mode, I have seen this happen if it senses an over current condition. Over current can easily happen if you start the servo in the wrong direction and you hit a hard stop. I highly recommend adding limit switches to help prevent this condition (and prevent damage to your hardware).

We found hardware debug using the BDC-Comm-92 PC application extremely useful. Lots of information at the bottom as to the condition of the servo. Also, we found that some of the KOP motors just have too much power for use as servos. There is a parameter on the second tab for max percent voltage. We found setting the max voltage to 60% (7.2V) help to dampen the servo loop.
