Product Description:
The HCS04.2E-W0640-N-04-DNNN is a drive controller manufactured by Bosch Rexroth Indramat as part of the HCS IndraDrive Controllers series. The unit converts three-phase mains energy into regulated DC-bus power and inverter output, enabling precise speed and torque regulation for industrial servo and induction motors used in material-handling, packaging, and machining cells. No fixed communication interface is included, so application buses are added through option slots to match the control system used in the machine.
It mounts vertically inside a control cabinet and connects to the supply through an M12 terminal set, while a separate M10 pair handles the Bu+/Bu− link. The specified tightening torque on that link is 24 Nm, which helps keep the conductors secure under vibration. The controller’s PWM stage operates at a nominal switching frequency of 4 kHz, and internal cooling air is moved by an integrated blower; when the cabinet is open vented to IP23, the airflow requirement rises to 1,200 m³/h. Internal semiconductor losses can reach 490 W / 610 W, so the enclosure must provide at least 10 dm² of free inlet and outlet area to maintain adequate airflow.
In sealed IP54 service, the airflow demand drops to 270 m³/h because the air path is shorter and directed across the heat sink. External braking choppers and filters add 4,440 W or 5,770 W of power dissipation, and total losses at full rated current reach 4,560 W or 5,890 W. The controller weighs 140 kg, so the cabinet should be reinforced before vertical installation, and the power, earth, and DC-bus output connections all use M12 terminals. The Po/Pa+/Pc− conductors are tightened to 41 Nm, and the integrated power supply can operate in infeeding or fed mode, allowing the unit to return regenerated energy to the grid or accept power from an upstream rectifier.
