Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-NN-NN-LF-FW is a drive controller built by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. This compact unit houses power electronics and control logic that regulate the torque, speed, and position of connected IndraDyn motors in automated machinery. By converting three-phase mains energy into controlled output and exchanging real-time data with higher-level PLCs, the device serves as the central axis interface in packaging lines, pick-and-place stations, and other motion-driven installations. Its combination of power conversion and closed-loop control supports coordinated motor response during repeated machine cycles. Because the drive and motor exchange feedback continuously, the axis can maintain stable motion even when load demand changes during operation.

The controller integrates a Multi-Ethernet interface for deterministic fieldbus traffic, allowing one communication port to support several industrial Ethernet variants without additional hardware. For grid connection, it accepts a 3-phase 200–500 V AC supply range, so the same model can operate in low- and medium-voltage plants. Peak output current reaches 28 A, giving the drive enough short-term capacity for acceleration of medium-frame servo axes. Thermal management is handled by internal blower cooling, which moves cabinet air across the heat sink and avoids external ducting. The housing has an IP20 rating, so the unit is finger-safe but still intended for installation inside an enclosure that protects it from dust and moisture.

The controller uses a BASIC control section for standard motion functions without integrated safety I/O. The unit is Design version 1. Feedback wiring connects through the IndraDyn encoder interface, which works with Hiperface and EnDat 2.1/2.2 protocols for absolute position reporting. The power module uses an infeeding and fed supply concept, allowing energy to be shared or regenerated through a common DC bus. This arrangement can reduce the power that must be drawn from the supply during changing load conditions, especially when several axes accelerate and decelerate in sequence.
