Product Brief Description

The Rexroth Indramat DKR02.1-W200N-B is a single-axis digital spindle drive controller from the DKR02 series, rated for 200A continuous output current. It operates on 3×400–480V three-phase mains power and is engineered to drive Indramat spindle motors, frameless motors and linear motors for high-power CNC machinery. This base unit comes without additional option cards, supporting regenerative energy feedback back to the power grid and integrated emergency stop function, widely used as replacement spare part for legacy machine tool automation systems.

Product Features & Functions
