Product Description:

Bosch Rexroth Indramat builds the HCS04.2E-W0640-N-04-NNNN as part of the HCS IndraDrive Controllers series. This HCS drive controller regulates high-power induction or synchronous motors in automated presses, plastic machines, and heavy conveyor axes by converting DC-link energy from an infeeding module into a precisely modulated three-phase output. This operating role makes it suitable for industrial motion systems that need stable torque and speed control under changing load conditions. The communication interface is not specified by this code, so bus couplers or Ethernet modules must be selected separately for cabinet integration.

Thermal management relies on air drawn through an integrated blower. In open IP23 cabinets, the controller moves 1200 m³/h of cooling air, while in sealed IP54 enclosures the flow requirement drops to 270 m³/h. At IP23, the cabinet openings must provide 10 dm² for inlet and outlet airflow. During full-load operation, the electronics dissipate 490 W internally and 4 440 W externally under the first power rating, while the second rating raises total loss to 5 890 W. The device uses an infeeding or fed supply arrangement, allowing it to draw DC-link energy or pass it downstream. At 400 V, continuous output reaches 387 A or 459 A, and the 60-second limit rises to 581 A. Under the first power class, the drive supports motors up to 200 kW and apparent power of 268 kVA.

Under the second power class, the controller can sustain a 60-second peak of 551 A and is sized for motors up to 250 kW. When operated at 400 V, its apparent output reaches 333 kVA, which supports rapid acceleration on heavy axes. The unit weighs 140 kg, so it requires a rigid panel mount and mechanical lifting during installation. Its size and blower-based cooling should be considered when planning enclosure spacing for high-power machinery.
