Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-EC-L3-NN-NW is a drive controller produced by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. It is intended for cabinet mounting and connects incoming three-phase power to multiple servo axes in industrial automation equipment. Acting as the central energy and control hub, the device converts line voltage into controlled motor waveforms while exchanging real-time commands with higher-level PLCs. By precisely regulating current and voltage, it supports repeatable positioning, synchronized speeds, and safe shutdown sequences across assembly, packaging, and handling applications.

It communicates over the factory network through the MultiEthernet interface, allowing parameter access and cycle-synchronous motion commands. Thermal management relies on an internal air blower, so no external ducting is required and cabinet airflow is simplified. The power stage can deliver up to 28 A of peak output current to the connected motor conductors, supporting dynamic acceleration profiles. Input tolerance covers a mains window of 3 x AC 200...500 V ±10%, enabling operation on a wide range of utility grids without tap changing. The housing carries an IP20 rating, which is suitable for clean electrical enclosures.

Functional safety is handled by the STO (Safe Torque Off) channel, which removes drive energy without delaying mechanical response when an emergency stop is requested. The control section installed in this configuration is classified as BASIC, providing standard regulator functions while leaving expansion slots unused. Dual feedback ports support a single-cable connection to motors that use IndraDyn Hiperface/EnDat 2.1/2.2 encoder feedback, providing high-resolution position data for closed-loop control. Power sharing inside a multi-axis system is handled by an infeeding and fed supply arrangement, letting surplus braking energy flow to adjacent drives instead of dissipating it as heat.
