Product Description:

The HDC01.1-A200N-DN01-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDC DuraDrive Controllers series. Within an automation cell, it supplies regulated power to AC motors, manages regenerative energy, and exchanges diagnostic data through its integrated DeviceNet fieldbus. By combining high-current output stages with internal bleeder circuitry, the unit simplifies cabinet wiring while providing motion control for conveyors, presses, and packaging axes. It mounts in multi-axis racks and interfaces with central PLCs through a dedicated bus connector. This arrangement lets the controller serve as both the power section and a communication node in distributed motion systems.

The controller delivers a rated output of 200 A, enabling it to run large induction or synchronous motors without current foldback. At the available carrier settings, it supplies continuous phase currents of 85 A at 4 kHz and 48 A at 8 kHz for sustained motor operation. These current values show the continuous output available at two switching frequencies commonly used to balance motor noise and thermal loading. Motor velocity resolution is supported by a maximum output frequency of 400 Hz. Energy returned during braking is buffered in a DC link with 4.7 mF of capacitance, and excess energy is converted to heat by an internal bleeder that dissipates 1.5 kW continuously. A 121 Ohm bus termination stabilizes the DeviceNet line when the X60 male 5-pin connector is the last node. A 24 Ohm soft-start resistor limits inrush current, and the unit can absorb up to 60 kWs of kinetic energy before thermal limits are reached.

During rapid deceleration or start-up, the bleeder stage tolerates a peak of 115 kW, helping keep the DC link within its working voltage range. Short bursts of current reach 100 A under the lower carrier setting and 68 A under the higher carrier setting, giving axis drives added headroom for jerk-limited motion profiles and changing load conditions. The control electronics require only 26 W, so auxiliary supplies can remain modest, and the combined housing and heat sink mass of 40 kg affects panel support and vibration isolation. The installed mass is important when the drive is mounted on back panels or rack structures with limited stiffness.
