Product Description:

The HCS02.1E-W0012-A-03-NNNV is a drive controller built by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. As a closed-loop power module, it interfaces between a plant’s three-phase mains and the DC bus that feeds IndraDyn servo motors. In automated cells, the unit provides current-regulated power conversion so axes can accelerate, position, and brake with repeatable accuracy. This arrangement also lets the drive regulate motor current precisely while responding to motion commands from the higher-level control system.

The enclosure is rated IP20, so the controller is intended for installation inside a cabinet where the housing remains protected from dust and incidental contact. A peak output of 12 A allows short bursts of current during rapid acceleration or transient load changes. The input accepts 3 × AC 200 to 500 V ±10%, which lets the same unit operate on a wide range of industrial mains supplies. Thermal management uses internal air cooling through an integrated blower, which moves cabinet air across the heat sink without external ducting. Supported motor groups fall within the 1.5 to 11 kW range, allowing the controller to serve both smaller servo axes and higher-power motion applications on the same DC link.

Energy exchange with the common bus is classified as infeeding and regenerative feedback, meaning the controller can both supply power and return braking energy to the DC link during deceleration. This operating mode supports applications with frequent braking, where recovered energy can be shared on the common bus instead of being dissipated locally as heat. Logic and gate-drive circuits receive power from DC 24 V from the DC bus, which keeps the control electronics supplied from a dedicated internal source. The unit is Design Version 1, so it matches the corresponding revision within this product line. It also belongs to the HCS02 platform, which uses the connector arrangement and diagnostic structure associated with the 02 family of IndraDrive controllers.
