Product Description:
The DKR02.1-W200N-BE79-01-FW is a digital AC drive controller manufactured by Bosch Rexroth Indramat in the DKR Drive Controllers series. It supplies and regulates high-power servo and spindle motors in automated production lines, where stable current control and coordinated velocity regulation are required for machining, conveying, and positioning tasks. A SERCOS fiber-optic ring carries motion commands from the CNC or PLC, and the internal control section synchronizes the current and speed loops with the bus cycle. This arrangement supports deterministic communication in multi-axis systems without relying on separate analog command wiring.
The power section is designed for three-phase mains of 3xAC 400–480 V, allowing connection to common industrial supplies used in high-power automation cabinets. An auxiliary supply of AC 230 V ±10% keeps the logic, fans, and contactors energized even when the main link is de-energized, which helps maintain control readiness during startup and service states. At a switching frequency of 4 kHz, the controller delivers a continuous armature current of 120 A and a continuous mechanical output of 47 kW. For short acceleration demands, it can provide a peak current of 141 A, giving additional current headroom for transient load changes. Parameter data and status information also travel on the same optical channel, which reduces the need for additional field wiring.
Thermal management relies on a built-in air blower that moves cooling air across the heat sinks and removes up to 1600 W of loss power from the enclosure. Because the unit is supplied without a brake chopper and operates on a rigid DC bus, regenerative energy must be handled by external components during deceleration. Position and speed loops use digital servo and resolver feedback, allowing the controller to work with inductive or optical encoder systems. The drive has a weight of 104 kg, so mounting and handling provisions must account for the mass of the assembled module. The product belongs to line 02 with design version 1 and function module version 01.
