Having trouble finding your model number? You may have an older version. Use the conversion tables on this page to find the current model.
All Micro-Speed® Smart-Move® drives now include version 2.2 updates, including I²T motor thermal protection and auxiliary Inputs. The I²T protection feature removes the need for separate motor overload relays in your control panel. Prior to version 2.2, the Smart-Move® MSM™series did not have model numbers ending with the letter “R”. The Smart-Move® version 2.2 is a direct replacement of previous Smart-Move® models (versions 2.1 and earlier).
Once you know the current model number, you can find more information about the units here.
