The pot. (potentiometer) is connected to a 3 phase motor with a drive (inverter) to provide the input signal command Or frequency Reference .... the more the pot. is rotated the more the voltages generated by the drive & hence the more the speed of the motor till the pot. reaches to its max. position ....
 

The exact answer should be given in the manual. Usually, there will be minimum an possibly a maximum potentiometer value. The minimum value is considering the permitted load current of 10V reference output supplying the potentiometer, the maximum value the input resistance of the analog input and respective voltage drop in mid position of the potentiometer.

I expect that values up to 10k or even 100k will work well. At worst case, the speed in mid position drops slightly below 50 %, but you'll still get full speed in clockwise position.
