Product Description:

The HCS01.1E-W0028-A-03-A-ET-EC-EC-L3-NN-FW is an HCS Drive Controller developed by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. Belonging to the HCS01 line, the unit serves as a power and motion regulator for servo-based automation axes, supplying controlled current and torque to connected IndraDyn motors. In industrial automation cabinets, it acts as the central actuator interface, translating fieldbus commands into precise motor movement while monitoring electrical and thermal conditions. This arrangement supports closed-loop motion on axes that require stable speed and position control during changing load conditions.

The control section communicates with higher-level PLCs through a MultiEthernet port, so one hardware platform can be integrated on EtherNet/IP, PROFINET, or EtherCAT networks without additional modules. The drive accepts motor feedback on two channels for Encoder IndraDyn Hiperface or EnDat 2.1/2.2 signals, which supports redundant position acquisition where the application requires it. Input power ranges from 3 x AC 200...500 V ±10%, giving the unit flexibility for a wide range of industrial mains supplies. Thermal energy is removed by internal air cooling that uses an integrated blower, so no external ducting is required. The housing has an IP20 rating, which means the controller is intended for installation inside a protected cabinet. The unit is design version 1.

During dynamic events, the power stage can supply up to 28 A peak current, which provides short-term current capacity for fast acceleration on medium-inertia axes. Drive-integrated functional safety is provided by STO, which removes torque-generating energy when the safety function is triggered. DC link energy management uses an Infeeding/Feeded topology, so common bus sharing with regenerative sections is possible. The device is paired with a BASIC control section code B for standard cabinet-mounted drive applications.
