SMC03A Position Set

I have an application where I need to set the position of a motor that has a 2K ohm pot attached. Does anyone have any example code on using the SMC03A to set motor position? The manual does a good job at describing how to set speed, but not position. Thanks!


Just set the feedback jumper to analog feedback mode, and all of your speed commands will now be position commands. Full speed reverse will correspond to one extreme, with smaller speeds going to the middle of the range, and full speed forward is the other extreme.

To make sure your mechanism doesn’t get torn apart if the feedback polarity is wrong, begin with everything in the middle of the range and be ready to cut power if the polarity is wrong. You can generally flip the motor or pot leads to get the direction correct.
