Product Description:

The DKR02.1-W300 drive controller is manufactured by Bosch Rexroth Indramat within the DKR Drive Controllers series. Intended for high-power motion tasks, the unit converts incoming three-phase supply energy into regulated drive current for large servo and spindle motors used in automated machining cells, material-handling lines, and similar equipment. By providing closed-loop current regulation, it keeps dynamic axes under consistent electronic control while its cabinet-mount design fits standard industrial enclosures.

Bosch Rexroth Indramat assigns the unit a continuous output capability of 300 A current rating, meaning the power section can deliver that amplitude of phase current without surpassing thermal limits. The controller removes heat through air cooling, an internal flow path that draws ambient cabinet air across the power electronics. A factory designation of version 1 marks the first hardware revision, defining component layout and diagnostic features that match the family’s initial firmware set. As part of the DKR Drive Controllers, it shares a common interface scheme, allowing straightforward pairing with Indramat supply modules and motor feedback networks.

Thermal management is further supported by a built-in blower, eliminating the need for external ducting and ensuring stable heatsink temperatures during extended duty cycles. The product belongs to line 02, a coding element that groups controllers with identical connector positions and bus interface geometry for consistent cabinet wiring. A nominal current of ≈ 300 A aligns with the published rating, indicating that continuous process loads can be handled at the same magnitude as the absolute limit specified above. Within the broader DKR series, this model therefore combines high current capacity and self-contained cooling to support demanding motion axes that must sustain heavy torque without intermittent pauses for temperature recovery.
