Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-NN-L4-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat and belongs to the HCS IndraDrive Controllers series. As a compact unit in the HCS01 line, it supplies regulated three-phase power to servo and induction motors, executing speed and torque commands issued by higher-level PLCs. The controller translates digital motion profiles into precise current and voltage outputs, enabling coordinated axis movement on assembly cells, packaging lines, and material-handling stations.

This controller integrates a MultiEthernet communication interface, so a single hardware platform can be used on EtherNet/IP, PROFINET, or EtherCAT networks without rewiring. Thermal management relies on internal blower cooling, which moves air through the heat sink fins and discharges heat into the cabinet space. For power, the unit connects to a three-phase mains supply of 3 × AC 200-500 V ±10%, allowing use on global 230 V or 460 V grids without tap changes. During acceleration or load surges, it can deliver a device peak current of 28 A, supporting short-term drive demand. The housing carries an IP20 rating, so the controller must be mounted inside a protective enclosure.

For functional safety, the power stage features the STO and SBC interface, which disconnects torque and controls a holding brake through a dual-channel circuit. The drive accepts feedback through the Encoder IndraDyn Hiperface/EnDat 2.1/2.2 port, allowing motor feedback connections for compatible systems. The control section is the BASIC control section, which provides standard positioning and velocity loops without optional extension cards, and the unit is design version 1. Interface 2 is left open for applications that do not require secondary feedback. The power module supports both infeeding and fed-back energy modes so shared DC bus installations can regenerate or distribute excess power.
