Product Description:

The HCS04.2E-W0420-N-04-NNBN is a drive controller manufactured by Bosch Rexroth Indramat and delivered within the HCS IndraDrive Controllers series. It is intended for cabinet-mounted motion systems where multiple axes share energy and operating data across a common control platform. As part of a modular motion system, it supplies regulated power to synchronous and induction motors, manages braking energy, and exchanges status data with higher-level automation. In production cells, this controller governs acceleration, speed, and position to match cycle demands while protecting connected motors from electrical and thermal stress.

The unit is listed with a continuous motor current of 300 A and a continuous overload rating of 257 A. The mains side draws 271 A at rated conditions from a three-phase 380 to 480 V supply, and the internal brake chopper routes surplus energy to a resistor bank. Short bursts are handled with a peak of 424 A for 2 s or 386 A for 60 s, allowing rapid torque rises without loss of regulation. A DC-link capacitance of 7.8 mF smooths these transients, and the integrated chopper can dissipate up to 200 kW for ten seconds. The power section is configured for infeeding or fed operation, so it can either supply the common DC bus or receive energy from an upstream rectifier depending on machine topology.

For sustained deceleration duty, the controller supports a permanent braking power of 100 kW, provided the internal air circuit moves 600 m³/h through the IP23 plenum created by the built-in blower. Control electronics are supplied by a dedicated 24 V DC bus, isolating logic from the main power stage. Separate control power allows monitoring and communication functions to remain available during main power events. The cabinet measures 330 mm in width, 380 mm in depth, and 950 mm in height, and the assembly weighs 80 kg, so panel reinforcement and adequate airflow paths are required when integrating the module beside other IndraDrive components.
