Product Description:
The HCS04.2E-W0420-N-04-DNBN drive controller is produced by Bosch Rexroth Indramat and belongs to the HCS IndraDrive Controllers series. It serves as the power conversion and regulation stage for industrial servo and induction motors, linking plant mains to the machine axis. By executing closed-loop commands and supervising protective thresholds, the unit stabilizes torque and speed in material-handling lines, packaging equipment, and other motion platforms that require coordinated multi-axis control.
Key electrical limits outline safe integration with the supply network. A branch fuse of 400 A pairs with upstream breakers to clear line faults, while the logic section draws only 72 W of auxiliary power. The inverter can deliver up to 300 A of continuous motor current, and the converter side accepts a rated input of 271 A from the feeder conductors. For high-capacity installations, the power stage carries a short-circuit withstand rating of 42000 A rms, allowing the controller to sit on reinforced busbars without extra isolation hardware. These values set the electrical envelope used when selecting cables, contactors, and thermal sensors for the drive panel.
Thermal management and mounting clearances help maintain reliable operation once the system is energized. The power modules dissipate 3710 W, so the internal blower moves 600 m³/h of air in IP23 cabinets or 165 m³/h behind IP54 covers. To keep pressure low, at least 7 dm² of free inlet and outlet area is needed, and 200 mm of top or bottom clearance must be respected. Air flows from front to rear, matching the M12 DC-bus jumper layout. Physical dimensions of 782 × 330 × 380 mm and a mass of 80 kg affect panel reinforcement and lifting requirements, while the infeeding/feeded arrangement supports common-bus operation at a rated control voltage of DC 24 V.
