Product Description:

The HCS03.1E-W0100-A-05-NNNV-AA is a drive controller manufactured by Bosch Rexroth Indramat as part of the HCS IndraDrive Controllers series. The unit acts as the central power stage between the plant's three-phase mains and connected servo or induction motors, providing regulated DC-bus energy and dynamic braking in automated machinery. As an HCS drive controller, it coordinates axis torque, speed, and positioning signals from higher-level motion logic, thereby supporting multi-axis packaging lines, material-handling systems, and general industrial equipment.

The controller accepts a mains supply of 3 × AC 400…500 V +10 % / −15 %, allowing installation on common factory power networks without a step-down transformer. Within this range, the integrated power electronics can deliver a device peak output of 100 A, a rating used for short acceleration bursts or rapid braking events. Continuous airflow is provided by an internal blower, and this cooling method is specified as internal air cooling, which removes heat directly from the heat sink so no external ducting is needed. The enclosure is rated IP20, so the unit must be mounted inside a closed electrical cabinet. Drive variants in this housing cover a power range of 15 to 75 kW while retaining the same mechanical footprint.

The control electronics are supplied with 24 V DC from the DC bus, and the integrated brake transistor diverts excess energy during regeneration. The power stage supports infeeding and fed operation, meaning it can both return energy to the supply grid and receive power from upstream rectifiers, which simplifies common-bus topologies. This unit is design version 1 in the HCS03 line, and voltage code 05 indicates 500 V-class components. The unpowered control logic, diagnostic LEDs, and encoder interface remain standard across the HCS drive controller product type.
