Product Description:

The HDC01.1-A100N-PB01-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HDC DuraDrive Controllers series. This unit interfaces between the DC bus and multiple servo axes, regulating current and dissipating regenerated energy so motion systems remain within electrical limits. Its housing weighs 35 kg, so it is typically installed in a floor-standing cabinet. In automated cells, it supervises acceleration, deceleration, and safe power removal, making it a central component for conveyor lines, pick-and-place gantries, and packaging machinery.

During steady operation, the integrated bleeder network can continuously absorb 0.5 kW of regenerated power, while the output stage supplies up to 40 A at a 4 kHz switching frequency, or 32 A when the carrier is raised to 8 kHz for long duty cycles. A separate charge circuit injects 7.0 A for 17 ms to precharge the DC link, minimizing inrush when the cabinet is energized. The power section draws 26 W for its control electronics and buffers energy with 2.35 mF of bus capacitance, providing low-ripple voltage to downstream inverters. At a 400 V DC link, the module can deliver 6.0 kW to connected axes, or 7.2 kW at 480 V, and its current headroom peaks at 100 A for short bursts such as rapid indexing or shock-load recovery.

During regenerative peaks, the bleeder path accepts 57.4 kW for fractions of a second, shunting energy through the internal 12 Ohm resistor until the capacitors settle. Total absorption is limited to 31 kWs per event, and each braking window must respect the 0.54 s load-cycle on-time so downstream devices are not overstressed. When acting as the DC supply for inverter stages, the controller supports modulation frequencies up to 400 Hz, allowing high-speed servo loops to receive stable power from the link.
