Product Description:

The HDC01.1-A040N-PB01-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDC DuraDrive Controllers series. In an automated line, it forms the power and communication hub between the mains supply and a synchronous or induction motor, regulating speed, torque, and dynamic braking without extra relay logic. By integrating command, bus, and energy-handling circuits in one 12 kg enclosure, it simplifies cabinet layouts and reduces wiring in material-handling cells, packaging machines, and similar motion-focused equipment.

The controller exchanges setpoint and status data through a Profibus-DP interface, allowing direct connection to PLCs that manage coordinated axes. Its output stage is rated for 40 A, which is the continuous motor phase current the unit can sustain without thermal derating. When connected to a 400 V DC link, it can return or supply up to 0.65 kW of bus power, while surplus energy is dissipated continuously at 0.075 kW to keep the link voltage within limits. Heat from these functions is removed by natural convection, eliminating fans and supporting use in dusty areas. The internal logic draws only 26 W of control power, and the charging circuit limits inrush with a 6.0 A maximum current applied for a 12 ms pulse.

Transient events are handled by a peak bleeder channel rated at 11.5 kW, backed by storage that can absorb 5 kWs of mechanical braking energy before external dumping is required. A soft-start resistor rated at 60 Ohm moderates capacitor charging, protecting the supply fuses and the link components. The DC bus filter uses 0.585 mF of nominal capacitance, and an overvoltage threshold of 40 V across the control electronics helps protect low-level circuits. For motor brakes, the integrated contact can switch up to 4 A at 40 V DC, providing fail-safe holding without an external relay.
