Product Description:

Bosch Rexroth Indramat manufactures the HDC01.1-A100N-CN01-01-FW, a drive controller positioned within the HDC DuraDrive Controllers series. The unit manages power conversion and feedback tasks for servo axes, and its CANopen fieldbus link places it directly on distributed automation networks for coordinated motion and diagnostic data exchange. It is intended for automated systems that need one controller to handle both axis regulation and network communication within the same cabinet layout.

The controller transmits process data over CANopen through a D-Sub 9-pin connector, enabling direct connection to other nodes on the network. At an 8 kHz switching frequency, it can deliver a continuous phase current of 21 A, and when the pulse frequency is reduced to 4 kHz, the sustained current rises to 40 A. Applications that demand brief surges, such as rapid indexing, can draw up to 100 A for short intervals with 17 ms pulse windows. Motor speed is regulated by a pulse-width-modulated output that can reach 400 Hz, permitting use with high-speed spindle or blower motors. A 26 W supply at terminal X1 powers the logic section, while capacitors totaling 1.2 mF absorb line disturbances and stabilize the DC link during rapid load changes.

The internal bleeder circuit dissipates regenerative energy continuously at 0.5 kW and tolerates spikes up to 57.4 kW, while a 12 Ω soft-start resistor helps limit inrush current and clamp bus voltage during deceleration. Thermal modeling allows 31 kWs of energy to be absorbed before protective shutdown is triggered, which helps protect the semiconductors during heavy braking events. The housing has an IP20 protection class, indicating finger-safe access while still requiring cabinet installation with forced airflow. Total mass is 35 kg, so the mounting surface must support that static load and still provide clearance for heat sinks and field wiring.
