NEMA 4X Washdown Drive


This module enables the drive system designer to solve more complex applications by providing additional inputs and outputs that the Commander SX can access locally. These connections on 12-pin and 3-pin removable terminal strips are programmable using SXSoft or the drive’s keypad. Their assignments are stored within the drive’s memory.
