The Bosch Rexroth Indramat HCS04.2E-W1540-N-04-NNNN is a drive controller from the HCS IndraDrive Controllers series, with a typical motor power of 630 kW and continuous brake power of 400 kW. It can provide a continuous current of 1126 Amps and has a maximum current of 1520 Amps for 2 seconds. The controller is cooled using an integrated blower with an air volume of 2400 cubic meters per hour and produces a sound pressure level of 75 decibels.

Product Description:
Bosch Rexroth Indramat manufactures the HCS04.2E-W1540-N-04-NNNN as part of the HCS IndraDrive Controllers series. This drive controller regulates high-power induction or synchronous motors in large conveyors, presses, or test benches by coordinating the infeed unit and the inverter section in a single housing. It works as an infeeding and regenerative unit, so returned energy can be fed back to the grid or shared on the DC bus. Because no dedicated fieldbus or Ethernet port is listed, the communication interface is not specified in the data set, and integration relies on optional expansion modules supplied separately.
The controller supplies motors rated near 630 kW while delivering a continuous output of 1126 A. Thermal management uses an internal blower that moves 2400 m³/h of air, and this airflow must pass through cabinet openings totaling at least 20 dm² to prevent heat accumulation. A DC bus capacitance of 31.2 mF smooths voltage ripple during load changes and buffers regenerated energy. For short braking cycles up to ten seconds, the drive can absorb 750 kW, while longer braking is limited to 400 kW. The cooling method, rated sound pressure level of 75 dB(A), and power dissipation of 10.53 kW at nominal input set enclosure ventilation and acoustic shielding requirements on the machine floor.
On the mains side, the unit draws 1037 A continuously, so upstream protective gear must withstand the declared 50 kA short-circuit prospective current. Peak torque demands are handled by a two-second current ceiling of 1520 A, and if the overload lasts one minute the allowable value falls to 1351 A. Internal semiconductor and busbar heating during overload is reflected in the dissipated heat of 10530 W. Proper clearance around fan inlets, adherence to the minimum 20 dm² airflow path, and isolation of the 75 dB(A) noise source support reliable operation without external chillers.
