 There is little clear information on the topic since running them off inverters is an extreme minority position, but it appears that speed controls work best on PSW inverters.  They may run on MSW but seem unable to reduce power less effectively (see below) and may run hotter.  There is little clear information on the topic since running them off inverters is an extreme minority position, but it appears that speed controls work best on PSW inverters.  They may run on MSW but seem unable to reduce power less effectively (see below) and may run hotter. 
  
-While resistive loads don't care about MSW vs PSW, inductive loads like motors will run hotter and "notchier" on MSW.  So you might want to run the latter off PSW whether or not a controller is used. +While resistive loads don't care about MSW vs PSW, motors will run hotter and "notchier" on MSW.  So you might want to run the latter off PSW whether or not a controller is used.

 >> ...there is a hidden adjustment potentiometer inside for minimum power setting. Wall dimmer switches have these as well. I was able to adjust it, but I’m waiting for my tachometer to get it where it needs to be. By the sound of the motor, I can tell it will go down enough. They really should disclose this adjustment in the instructions… Note: The hidden adjustment is soldered onto the top side of the PCB inside but you need to use a small flathead screwdriver to adjust it from the back after removing the back cover. >> ...there is a hidden adjustment potentiometer inside for minimum power setting.
