The Bosch Rexroth Indramat DKR03.1-W200N-BT49-01-FW is a digital intelligent AC drive controller from the DKR Drive Controllers series. It has a continuous current of 92 Amps at 4 kHz, a peak current of 141 Amps, and a continuous power output of about 35 kW. The controller uses air cooling with a built-in blower, weighs approximately 49 kilograms, and features a SERCOS command interface along with digital servo and resolver motor feedback.
Internal Product Review
The DKR03.1-W200N-BT49-01-FW is a digital intelligent AC drive controller with a SERCOS command interface and built-in blower cooling. Continuous output at 4 kHz reaches about 35 kW with 92 A continuous current, giving the unit strong capacity for demanding servo applications. Digital servo and resolver feedback support precise motor integration, and 141 A peak current stands out as a key performance advantage.

Product Description:
The DKR03.1-W200N-BT49-01-FW is a digital intelligent AC drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It is intended for large synchronous and induction motors used in automated presses, metal-cutting machines, and multi-axis transfer lines. As a pulse-width-modulated inverter, it supplies precisely timed current and voltage commands so the connected motor can follow demanding speed and torque requirements in coordinated motion systems.
The drive exchanges setpoints and diagnostic data through a SERCOS interface, so real-time motion tasks can be coordinated across the control network. At a 4 kHz switching frequency, it provides a continuous output of 92 A, while transient loads can be covered by a peak capability of 141 A. This output corresponds to about 35 kW of continuous mechanical power for connected axes. The power section accepts a three-phase supply of 3 x AC 400 to 480 V with a tolerance of ±10 percent, which supports installation on common industrial mains. The DC bus is specified without a bleeder, so regenerative energy must be returned to the line or absorbed by external hardware. The unit is in current rating class 200, line series 03, design version 1, and function module version 01. Dual-channel digital servo and resolver feedback are supported for position and speed control with sub-millisecond update times.
Thermal management relies on air cooling with a built-in blower, so the controller uses cabinet airflow rather than an external heat exchanger. Low-power electronics are supplied by a separate AC 230 V control voltage, which allows parameter memory and fieldbus communication to remain active during main-power isolation. During full-load operation, the unit releases 1200 W of heat, so the enclosure must remove that heat to keep internal components within their operating range. A shipping mass of 49 kg requires reinforced panel mounting and suitable handling equipment during installation. Cabinet layout should leave clear airflow paths around the power section to support steady cooling during continuous-duty operation.
