Product Description:

The HCS03.1E-W0100-A-05-NNBV-AA drive controller is produced by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. As an intelligent power module, it links servo or induction motors to the plant’s DC bus, executes motion commands, and monitors load conditions. The unit belongs to the HCS03 line size, which identifies the mechanical frame and connector layout used by this housing. In automated packaging, material handling, and forming stations, it supplies variable three-phase power so axes can accelerate, brake, and hold position under closed-loop control. Because current, voltage, and load conditions are monitored continuously, the controller can respond quickly to changing axis demand during start, stop, and synchronized movement.

Its integrated blower uses internal air cooling through the heat sink, so thermal regulation is handled inside the unit. The controller can deliver up to 100 A of peak output current, allowing short-term torque surges without tripping the inverter stage. Input mains compatibility covers 400–500 V AC on a three-phase supply with a +10%/-15% tolerance, so the same hardware can operate on European or North American 460 V grids. Within that supply range, the power section supports a continuous output range of 15–75 kW for medium-size extrusion, press, or gantry drives. The enclosure has an IP20 rating, which protects against finger contact and requires cabinet installation. This layout keeps the power electronics enclosed while allowing the drive to serve demanding motion applications with frequent acceleration and deceleration.

The energy interface supports infeeding and regenerative operation, so the module can either draw power from or return energy to a common DC link during braking. Control electronics, fans, and sensors receive stabilized 24 V DC power taken directly from the DC bus, eliminating the need for a separate auxiliary supply. The product is built as Version 1 within this generation. Its mains segment is marked as code 05, which helps identify the voltage class in mixed drive systems. Returning braking energy to the common DC link can reduce wasted heat in systems with frequent deceleration, and using the bus-derived control supply simplifies panel wiring inside the cabinet.
