Product Description:

The DKR02.1-W300N-BA06-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It is a digital intelligent AC drive controller that links plant power networks to high-torque servo and spindle motors, converting incoming energy into regulated three-phase output for coordinated motion. This hardware is commonly installed in machining centers, gantry systems, and packaging lines where rapid current control supports accurate position and speed loops. Because it manages current regulation and motor control in one package, it supports responsive starts, steady running speed, and repeatable axis behavior during cyclic operation.

The controller’s logic and gate arrays are energized by AC 230 V ±10 %, while the power section is fed from 400–480 V AC ±10 % three-phase mains. At a switching frequency of 4 kHz, the inverter can supply a continuous armature current of 141 A, and its thermal design allows the attached motor to deliver about 55 kW of mechanical output without derating. Short acceleration bursts are covered by a peak output of 212 A, which helps the drive handle temporary load increases during ramping and rapid motion changes. An analog interface supports installations that do not use fieldbus communication, and dual-channel motor feedback combining digital servo signals with resolver tracks closes the control loop for both precision axes and high-speed spindles.

Cooling is provided by a built-in air blower, and the airflow removes up to 1800 W of heat from the heat sink. The unit belongs to current class 300. It is built in design version 1, carries function module version 01, and is part of line series 02. A rigid DC link operates without a brake chopper, so regenerated energy is returned to the mains or routed to an external resistor bank used by the machine. Despite its capacity, the assembly weighs 104 kg, which helps cabinet layouts account for mounting support and panel loading.
