R911282747
The R911282747 (DKR02.1-W300B-BE37-01-FW) is a high-performance DKR type drive controller produced by Bosch Rexroth Indramat. Capable of controlling and monitoring a variety of motors such as linear, main spindle, and frameless spindle motors, this complex device offers broad speed ranges and superior control when paired with servo drives. Designed with an emergency stop-shutdown device (ESSD) and a mains contactor, the DKR02.1 drive controller can be customized with up to five different modules based on specific application requirements.
The supported servo motors, typically with an output power ranging from 10 kW to 93 kW, make the DKR02 drive controllers compatible with paper processing machines, printing equipment, and NC-controlled machine tools. The well-designed heat dissipation system incorporates an internal built-in blower and heatsink. The R911282747 (DKR02.1-W300B-BE37-01-FW) can discharge a maximum of 1800 Watts of heat at peak current. Additional features include a bleeder resistor and a digital servo motor feedback with a resolver. It utilizes the SERCOS interface for error diagnostics and communication commands. Its power voltage is rated at 3 x 400 – 480 AC, ± 10%, with an operating frequency of 50 – 60 Hz and a control voltage rating of 200 VA. The controller offers a continuous current of 141 Amperes at 4 kHz switching frequency and 110 Amperes at 8 kHz.
