Product Description:

The HCS04.2E-W0350-N-04-DNBN is a drive controller produced by Bosch Rexroth Indramat in the HCS IndraDrive Controllers series. It functions as the power interface between the plant supply and the DC bus that serves multiple servo or spindle inverters, providing regulated energy flow and coordinated braking for industrial automation cells. The power section can operate in either infeeding or fed-back mode, which allows excess energy to return to the mains instead of being converted into heat during deceleration.

The housing has a width of 350 mm, a height of 782 mm, and a depth of 380 mm. With a mass of 74 kg, the unit requires a cabinet layout that accounts for both installation space and support capacity. Thermal management uses internal air through an integrated blower that pulls fresh air across a 7 dm² inlet and outlet area, with flow rates of 600 m³/h in IP23 installations and 145 m³/h in IP54 cabinets. A DC bus capacitance of 7.8 mF smooths regenerated energy, while external and internal control circuits are both supplied with 24 V DC to keep logic active during main power interruptions. Continuous heat loss is 2520 W at operating point P1 and 3330 W at the higher P2 level. For load dissipation, the unit can release a permanent braking power of 85 kW into its integrated resistor network.

During short deceleration bursts, the controller tolerates a maximum brake power of 165 kW for ten seconds, allowing rapid stops of high-inertia tooling. Command loops execute on a nominal clock frequency of 4 kHz, enabling tight current and speed regulation when used with IndraDrive inverters. Mechanical reliability is backed by a shock resistance of 7 g for 11 ms, helping protect internal assemblies during transport and on machines that transmit brief mechanical impacts.
