Product Description:

The DKR02.1-W300Z-BA03-01-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 installed between the power supply and a synchronous or induction motor to regulate torque, speed, and dynamic response in automated machinery. By converting motion commands into regulated three-phase output, the unit serves as the actuator interface in multi-axis industrial systems. This operating role makes it suitable for applications that start and stop frequently or must maintain stable motion under changing load conditions.

The command layer uses an analog interface that accepts ±10 V reference signals for torque or velocity setpoints. This arrangement lets the controller follow external command signals from compatible motion hardware without requiring a digital command channel. At a current control frequency of 4 kHz, the drive delivers a continuous phase current of 141 A, which supports mechanical output close to 55 kW during continuous operation. Support electronics operate from a control supply of AC 230 V ±10 %. Heat is removed by air cooling with a built-in blower, which directs airflow across the power section and helps maintain stable operating temperature during long duty cycles.

During rapid acceleration, the unit can supply a peak phase current of 212 A when short-term motor demand increases. Power is drawn from a mains supply of 3×AC 400–480 V ±10 %, and the controller has internal losses of 1800 W. Current modulation uses digital servo and resolver feedback from the connected motor so the control loop can respond to load changes with stable regulation. The unit has a mass of 104 kg, which is an important consideration for panel support and lifting during installation. The installed BA03 function module is version 01, and the product is assigned to line 02 with design version 1.
