Product Description:

The HDC01.1-A200N-PB01-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDC DuraDrive Controllers series. It regulates DC bus energy and switches power devices to coordinate servo axes in industrial machinery. By offering fieldbus connectivity, it links higher-level PLCs with the motor power stage, letting the automation system execute coordinated motion sequences. It is suited for applications that require coordinated speed and torque control across servo-driven machine sections.

At the communication layer, the controller presents a Profibus-DP interface that transmits setpoints and diagnostic words in real time. The power section is sized for a rated motor current of 200 A. When the pulse-width-modulation carrier is set to 4 kHz, it can deliver a continuous secondary current of 100 A; at 8 kHz, the sustained value decreases to 68 A because of higher switching losses. Excess DC bus voltage is routed to an internal bleeder with a continuous dissipation capacity of 1.5 kW. A control pulse duration of 17 ms synchronizes the bleeder with drive regeneration. Cooling air is moved by a 45 W fan, and the logic section receives 26 W of supply through connector X1.

Transient braking events are handled by a peak bleeder rating of 115 kW, matched with a maximum energy absorption of 60 kWs so the bus voltage remains within permissible limits during deceleration. The capacitor bank stores charge in a 4.7 mF reservoir, while a charging circuit limits inrush to 7.0 A before the contactor closes. Installation weight is controlled at 40 kg, which supports panel mounting in cabinets sized for high-power drive hardware. The charging circuit helps reduce electrical stress on upstream components during power-up, and the stored energy supports the drive during rapid load changes.
