Product Description:
The HCS02.1E-W0028-A-03-LNNN-AA belongs to the HCS IndraDrive Controllers series manufactured by Bosch Rexroth Indramat. As an industrial drive controller, it converts three-phase supply power into regulated output for servo and induction motors used on production lines, handling units, and processing machines. Within an automation cell, it coordinates speed and torque commands from a higher-level PLC and forms the electrical interface between the mains supply and the mechanical axis under its control.
The controller draws power from a three-phase network rated at 200–500 V AC ±10%, letting one hardware model cover many regional grids. Its continuous output capability spans 1.5–11 kW, a range suited to small conveyors through mid-sized forming drives. During rapid acceleration, the current can rise to 28 A, which sets the peak load that connected fuses and busbars must withstand. Thermal energy created by the power electronics is removed by internal air cooling with an integrated blower, eliminating external ducting and simplifying cabinet layout. The housing carries an IP20 rating, so it requires installation inside an enclosure while still allowing direct access for wiring and diagnostics.
Additional parameters refine how the unit is integrated. The hardware corresponds to design version 1, indicating the first mechanical revision of this controller. It is part of the HCS02 line, which uses standardized dimensions and mounting rails across the 2 kW to 30 kW class. Power is exchanged over a common DC bus that can operate in an infeeding and fed topology, and this arrangement supports energy recovery from braking axes into the supply section. Although the communication interface is not specified, the base hardware is an HCS Drive Controller, so a suitable fieldbus module can be selected to match the plant network without changing the power stage.
