Product Description:

The HCS04.2E-W0290-N-04-NNBN drive controller is manufactured by Bosch Rexroth Indramat and is part of the HCS IndraDrive Controllers series. Installed between an infeeding supply section and one or more servo axes, it converts DC bus energy into regulated three-phase output for precision motion tasks in automated cells, packaging machines, and material-handling equipment. Its integrated control electronics handle gating, current regulation, and communication so commanded torque and speed reach the connected motor without external sequencing hardware. This arrangement allows the controller to act as the cabinet-mounted power stage for demanding servo applications that require stable motion response during changing loads.

During transients, the power stage can deliver a peak current of 290 A, giving the axis short-term headroom for rapid acceleration. The IGBT bridge is modulated at a nominal clock frequency of 4 kHz, and the synthesized voltage supports motor operation up to 300 Hz. Cooling is provided by internal air cooling, so airflow is circulated through the chassis without external ducting. The controller is rated for Overvoltage Category III, so it can withstand switching surges found in distribution-level installations. A selectable power supply unit mode lets the device operate in either infeeding mode or fed mode.

Continuous output is maintained from -10 °C to +40 °C and up to 1000 m altitude, while derating begins above that height and remains acceptable up to 3000 m. Relative humidity may reach 95 % without condensation, and moisture buildup must be avoided to protect insulation and control circuits. The front and side panels meet an ingress rating of IP31, while the top is IP20 and the open bottom is IP00, so installation inside a closed cabinet is required. Storage conditions range from -25 °C to +70 °C. Air passages for the blower must stay clear to preserve cooling efficiency during standby periods and active operation.
