Product Description:

The HDC01.1-A040N-CN01-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDC DuraDrive Controllers series. The unit converts and regulates DC-bus energy so that induction or synchronous servo motors follow speed and torque commands in automated cells, conveyors, or packaging machines. By integrating bleeder circuitry and fieldbus communication, the controller streamlines panel layouts and simplifies setup in distributed machinery.

It supplies a rated phase current of 40 A, allowing sizable motors to accelerate without current foldback. During normal regenerative braking, the internal resistor can continuously absorb 0.075 kW, while 10 A and 5 A continuous armature currents are available when the switching frequency is set to 4 kHz or 8 kHz, respectively. A 26 W control power input keeps logic and sensors active independently of the power stage. The DC link is stabilized by 0.585 mF of capacitance, reducing voltage ripple when load cycles are uneven, and output pulses can be modulated up to 400 Hz to support high-speed spindles. Heat is removed through natural convection, so no forced-air fans are required, and the enclosure meets the IP20 protection class for mounting inside closed switchgear. A 60 Ω soft-start resistor limits inrush current and extends capacitor life.

For brief decelerations, the bleeder accepts energy surges up to 11.5 kW, and the DC bus can store 5 kWs before external dissipation is necessary. Motion commands and diagnostics travel over the CANopen protocol through a D-Sub 9 connector, letting the drive share status with PLCs on a deterministic fieldbus. Motor leads may reach 25 m without exceeding the allowed voltage drop, which is useful when cabinets are separated from moving axes. The controller weighs 12 kg, which should be considered when planning rail strength or swing-panel hinges, yet its footprint remains compact enough for multi-axis stacks.
