I'm not directly familiar with the CT products but, generally, no scaling is needed for a 0-10V speed pot input signal. You do need to tell the drive what speed 0v represents and what speed 10v represents but that is all for the input.
Normally, drive analog outputs default to either 0-10V or 4-20ma with the minimum being zero speed and maximum on the range being maximum speed. No scaling needed here either unless you want something else (2-10V, 0-20ma, 0-5v, etc.)
Usually scaling adjusts the maximum end of the signal range and offsetting adjusts the minimum end. So, for example, a 2-10V signal has a 20% offset on the bottom and 100% scaling on the top. A 0-5v signal would have no bottom end offsetting and the scaling set at 50% on the top. A 1-6V signal would have 10% offset and 60% scaling.
Unfortunately, while what I've described to you is common, it may not apply to your specific drive. Quality time spend in the instruction manual is the only way I know of to determine with precision what you've got.
