For the Vic, I believe the answer is "yes" (and perhaps significantly) but I have no data to confirm that.

If I am right (that the variation of the Vic's "effective % of full scale output vs input command" curve varies significantly with working load), then it wouldn't make much sense to worry too much about getting the "linearization function" exactly right when the load varies greatly.

Does anyone have such data¹ they'd be willing to share?


¹ e.g. with a motor connected to the Vic: no-load motor speed vs input command to the Vic, and stalled motor torque vs input command to the Vic. Of course the data for the "stalled motor" curve would have to be limited to small inputs.
