Product Description:

The HDC01.1-A100N-IB01-01-FW drive controller is produced by Bosch Rexroth Indramat within the HDC DuraDrive Controllers series. It regulates three-phase AC motors by converting incoming line power into a controlled DC bus and modulated output stages suited for automated machinery. Installed in centralized cabinets, the unit manages braking energy through an internal bleeder circuit and stabilizes the shared DC link feeding multiple motion axes in assembly, packaging, and material-handling cells.

The controller communicates over the InterBus command interface through an incoming D-SUB 9 male connector and an outgoing D-SUB 9 female connector that supports line topology. Its power stage is rated for 100 A, while a secondary channel supplies 40 A continuously at a 4 kHz switching frequency. When connected to a 400 V DC link, the unit handles 6.0 kW of motoring or regenerative power, buffered by 2.35 mF of internal capacitance. Pulse-width modulation extends output frequency to 400 Hz, allowing high-speed spindle or servo operation. These current limits help keep the IGBT stage within its thermal range and support predictable torque during cyclic loading. This frequency ceiling suits induction, synchronous, and linear motors used in high-throughput conveyor lanes.

At power-up, the control electronics draw 7.0 A for 17 ms, after which normal logic consumption stabilizes at 27 W. Excess mechanical energy returned from the motor is routed to the bleeder resistor, and the circuit dissipates 0.5 kW continuously and withstands peaks of 57.4 kW, with a thermal absorption limit of 31 kWs. When the common bus is maintained at 480 V, the converter supplies 7.2 kW to the load, extending the usable speed range without external transformers. The 35 kg chassis mounts vertically in standard cabinets, and the communication pass-through keeps control wiring minimal.
