Product Description:

Bosch Rexroth Indramat produces the HCS02.1E-W0070-A-03-NNNV-AA as part of the HCS IndraDrive Controllers series. The unit interfaces between the plant power network and motor windings, converting line energy into regulated output for precise speed and torque control. It is installed in industrial automation cells where coordinated motion, quick acceleration, and dynamic braking are required on conveyor, packaging, and handling axes. In this role, it supports repeatable motion profiles during changing loads and frequent start-stop operation.

The controller uses internal air cooling through an integrated blower to move cabinet air across its heat sink. This keeps semiconductor temperatures within limits without external ducting, and the airflow path should remain unobstructed inside the cabinet. It handles a device peak current of 70 A, allowing short acceleration demands before current folds back to continuous ratings. Supported mains input spans 3 × AC 200...500 V ±10%, so the same model can be connected to common low- or mid-voltage three-phase supply systems. Within that range, it covers a continuous mechanical power window of 1.5 to 11 kW, which suits small indexing drives as well as medium-power spindle duties. The housing is rated IP20, and the control electronics plus the brake transistor receive auxiliary energy as DC 24 V from the DC bus.

Energy flow is managed by an integrated supply concept described as infeeding and regenerative operation. This means the module can return regenerative energy to the line or accept DC bus power from an upstream infeed, which supports modular cabinet layouts in multi-axis systems. The unit is built in design version 1, and its parameter structure matches other first-generation IndraDrive components. Parameter sets, safety contacts, and fieldbus terminals follow the electrical format used by the HCS02 line, which helps maintain consistent panel integration and shared DC bus arrangement across related controller setups.
