Product Description:
The DKR 3.1-W200N-BE37-00 drive controller from Bosch Rexroth Indramat belongs to the DKR Drive Controllers series. Designed for cabinet installation, DKR 3.1-W200N-BE37-00 regulates torque and speed for high-power servo motors used in presses, printing lines, and heavy-axis positioning. It links a three-phase mains supply to the motor through a rigid DC bus and forms the central actuator in SERCOS-based motion systems.
During continuous operation at a 4 kHz switching frequency the controller supplies 92 A of drive current, while short acceleration commands can draw up to 141 A without exceeding its semiconductor limits. Motor speed modulation is handled through a maximum output frequency of 800 Hz, allowing finely stepped velocity profiles for large synchronous machines. Control electronics are powered from a 230 V AC auxiliary line that may vary by ±10%, and an integrated air blower forces cooling air across critical components to maintain thermal stability.
The logic section consumes 200 VA of control power and communicates over the SERCOS interface, accepting digital servo or resolver feedback from the connected motor. Without a brake chopper, excess energy is returned to the rigid DC bus, which means thermal removal is essential; the blower channel carries away 800 W, and overall continuous losses reach 1200 W. An enclosure rating of IP20 confines usage to protected cabinets, where ambient temperatures up to 55 °C and elevations to 1000 m are permitted before derating.
