Product Description:
The DKR03.1-W200N-BA37-01-FW is manufactured by Bosch Rexroth Indramat and belongs to the DKR Drive Controllers series. It is a digital intelligent AC drive controller that supplies regulated power to large servo axes used in transfer lines, presses, and machining centers. This type of controller is intended for applications that require stable torque and speed control during repeated production cycles. The housing uses a built-in air blower, so heat is removed by forced air to keep internal components within their thermal limits during continuous operation.
A continuous current of 92 A can be delivered when the switching frequency is 4 kHz, providing sustained current to the connected motor windings. At the same frequency, mechanical output reaches approximately 35 kW, which is the power available to the connected motor without derating. The control electronics use an auxiliary supply of AC 230 V, while the main power section accepts three-phase input from 3xAC 400–480 V. Transient demand is supported by a peak capability of 141 A, which provides headroom for short acceleration bursts. The drive uses an analog command interface, and position data returns through digital servo or resolver feedback. The DC bus is rigid because the unit does not include a bleeder or brake chopper, and the nominal current rating is 200 to match the W200 identifier in the type code.
The controller is part of line 03 and uses the design release Version 1 with function module Version 01. Under full load, the electronics dissipate 1200 W, and this heat loss value is used when planning cabinet ventilation and estimating ambient temperature rise. The shipping mass is approximately 49 kg, which affects mounting support and handling during installation. These identifiers place the unit within the third design line of the product range.
