Links should be fixed now.

Here's an interesting visual. I wrote an awk script to read and convert the RPM vs Nm @ fixed IPW¹ raw data into a family of closely-spaced RPM vs IPW @ fixed Nm curves and plotted it with gnuplot. You can really see the change in linearity of the 884 as the load on the CIM increases.

Also, FWIW, here's a graphic of the 884 driving a 1500 ohm resistive load. You can see how linear it is. The non-linearity (when connected to a motor) comes from the interaction of the (slow) frequency the 884's output with the motor's inductance.
