Product Description:
The HCS03.1E-W0350-A-05-NNNV is a drive controller produced by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. It interfaces between three-phase plant power and the DC bus that feeds multiple servo inverters, managing both infeed and braking energy. By coordinating power distribution and protective monitoring, this controller serves as a core component in automated machining cells, packaging lines, and material-handling stations. In multi-axis systems, it supports a shared power path for connected drives during acceleration, steady operation, and deceleration.
For compatibility with plant power grids, the controller accepts a mains connection of 3 x AC 400–500 V with a tolerance of +10%/-15%. This input range suits common industrial distribution systems where line conditions can vary during operation. When paired with suitable inverters, it can deliver continuous output across 15 to 75 kW, which covers medium-size pump, press, and conveyor applications. Internal auxiliaries, digital I/O, and the braking transistor are energized through a DC 24 V supply derived from the shared DC bus, so a separate control transformer is not required. Thermal regulation is handled by internal air cooling through an integrated blower that draws air through the heat sink. The housing has an IP20 rating, so it must be mounted inside a cabinet to prevent contact with live parts.
Energy flow to and from the common DC rail is bidirectional because of the infeeding and regenerative power section, which allows line regeneration during motor braking. The device belongs to line code HCS03, which corresponds to its physical size and connector layout within the IndraDrive platform. The controller is Version 1, indicating the current release of this model. Parameter sets linked to Voltage code 05 match the rated mains window used by the protective circuitry, fuses, and pre-charge components. This layout allows the unit to operate in multi-drive systems without additional cooling ducts or external regenerative modules.
