Product Description:

The HCS02.1E-W0070-A-03-NNNN-AA is an HCS drive controller from Bosch Rexroth Indramat in the HCS IndraDrive Controllers series. It converts three-phase mains energy into regulated motor currents, enabling closed-loop speed and torque control in automated machinery. Installed in a control cabinet, the unit links servo drives to higher-level PLCs, although the communication interface depends on the surrounding hardware. The controller continuously adjusts motor power during start, stop, and load changes, making it suitable for packaging, material-handling, and general motion tasks. It can be used wherever accurate motor response is needed for synchronized conveyors, indexing units, and position-controlled mechanisms.

Its device electronics can deliver a peak output current of 70 A, which indicates the short-term torque available for acceleration or shock loads. The controller accepts mains supplies of 3 x AC 200...500 V ±10%, covering common 230 V and 400 V plant networks without transformer adaptation. Within that voltage window, it supports motors rated from 1.5 to 11 kW, so one unit can cover several axis sizes on the same machine. The enclosure has an IP20 rating, so the controller must be mounted inside a protected cabinet. Heat is removed by internal air cooling through an integrated blower, which helps maintain operating temperature in compact control panels. Because the supply range is broad, the same platform can be applied in machines built for different regional mains standards.

The power section uses an Infeeding / Feeded configuration, allowing regenerative energy from decelerating axes to be returned to the DC bus or mains rather than dissipated in resistors. Returning energy to the shared bus can reduce heat buildup in systems that cycle through repeated deceleration phases. The unit is version 1 and belongs to the HCS02 line, so its mechanical footprint and connector layout match other units in that sub-family. This layout supports cabinet-mounted servo systems that use centralized drive control across multiple machine axes.
