Product Description:

The HDC01.1-A040N-IB01-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied as part of the HDC DuraDrive Controllers series. The unit conditions DC-bus energy and modulates switching devices to command servo or induction motors mounted elsewhere in the machine. It also houses protective bleeder circuitry and a fieldbus interface so that axis feedback, diagnostics, and motion commands can be exchanged with the main control system. Typical roles include coordinating pick-and-place axes, feeders, and other precision motion stages in automated production cells.

For continuous operation, the power section is dimensioned for a rated motor current of 40 A, while the logic board draws only 27 W of separate control power. A DC-bus capacitance of 0.585 mF stores charge so the drive can supply short bursts of acceleration current; the reservoir can be charged at up to 6.0 A and withstand transient excursions up to 40 V for 1 ms. Velocity regulation bandwidth is supported by an output frequency ceiling of 400 Hz. Command and status data are exchanged via the InterBus protocol through matched 9-pin D-Sub male and female connectors, allowing plug-through wiring between successive drives. Heat is removed solely by natural convection, and the electronics survive shocks of 15 g for 11 ms without performance loss.

Regenerative energy that returns to the DC link is routed to an internal bleeder stage. Under steady loads, this resistor dissipates 0.075 kW, yet it can absorb peaks up to 11.5 kW and a total of 5 kWs to protect the capacitors from overvoltage. The chassis carries an IP20 protection rating, is designed for control cabinets where no direct dust or fluid jets are present, and continues to function at ambient humidity levels as high as 95%. With a mass of 12 kg, the controller can be mounted on standard rail hardware without additional reinforcement.
