Product Description:

The HCS01.1E-W0028-A-03-E-S3-EC-EP-L3-NN-FW is an HCS drive controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. It serves as the axis-specific element of a modular motion system, converting commanded torque values into controlled motor currents for packaging, material-handling, and light assembly equipment. The controller combines its power stage, control section, and internal blower in one unit, so no external cooling accessories are required. It is intended for coordinated axis control where repeatable motion and stable current regulation are needed during continuous machine operation.

The drive accepts a three-phase supply of 3 × AC 200…500 V ±10%, allowing it to operate on a wide industrial voltage range. When rapid acceleration is required, the power section can deliver a peak output of 28 A to the connected motor windings. Command and diagnostic data are exchanged over the SERCOS III real-time interface, which coordinates multiple axes with very tight timing. An integrated blower moves air through the chassis, and the housing maintains IP20 protection for installation inside electrical enclosures. A built-in safety channel provides STO (Safe Torque Off), which removes torque-producing energy when the safety circuit opens.

The control section uses the ECONOMY variant and is paired with the power module according to the product configuration. The unit uses an infeeding and fed supply concept, so it can receive DC-bus energy or return regenerated energy to upstream modules. Position feedback is handled through the Encoder IndraDyn Hiperface/EnDat 2.1/2.2 port, which allows direct connection to compatible feedback devices without separate converter hardware. The controller is identified as Design Version 1, and its layout is intended for use in modular drive assemblies that share a common DC-bus structure.
