Product Description:

The HDC01.1-A040N-SE01-01-FW drive controller belongs to the HDC DuraDrive Controllers series from Bosch Rexroth Indramat. It forms the central regulating element between an industrial power supply and the servo motor, commanding torque, velocity, and position while managing regenerated energy on the DC link. Installed inside electrical cabinets, the unit contributes to automated assembly cells, gantry axes, and packaging equipment by supplying controlled three-phase power and real-time communication to each connected drive module.

During operation, the bleeder dissipates 0.075 kW of regenerative energy to hold the DC bus voltage steady during deceleration. For brief braking events, it tolerates up to 11.5 kW, giving headroom for emergency stops. The power stage delivers a continuous current of 40 A, so motors with similar demand can be driven without derating. Only 25 W of auxiliary power is needed to run the control electronics, minimizing standby draw. A capacitor bank of 0.585 mF smooths the DC link and supports transient loads. Natural convection cools the heat sink, and a 60-ohm soft-start resistor limits inrush when the bus is charged.

The power stage can modulate carrier frequencies up to 400 Hz, supporting high-speed spindles and finely stepped servo profiles. Command and feedback data travel over the SERCOS interface, ensuring synchronized positioning across multi-axis networks. The enclosure has an IP20 protection category, so it is finger-safe but not sealed and must be kept in a closed cabinet where ambient humidity does not exceed 95% non-condensing. At 12 kg, the controller is intended for cabinet mounting, and its 420 mm height, 105 mm width, and 250 mm depth fit common drive bays. The design can absorb a cumulative 5 kWs of braking energy without exceeding component limits.
