Product Description:
The HCS01.1E-W0028-A-03-B-ET-EC-PB-L4-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. It belongs to the HCS01 line. The unit serves as an axis inverter that converts plant AC supply into a regulated DC link and then into pulse-width-modulated phase output. This allows accurate speed and position control of servo or induction motors in packaging, material handling, and general automation cells.
The power stage accepts a three-phase mains input of 3 x AC 200...500 V ±10%, letting one hardware type operate on common industrial grids. The wide input range helps the same unit fit multiple supply standards. Thermal management relies on internal air cooling through an integrated blower, so no external ducting is required. During acceleration, the inverter can deliver up to 28 A of peak current to the connected motor. Its cabinet-mount enclosure carries an IP20 rating, which protects against finger contact but requires installation inside a protected control cabinet. Plant networks reach the controller through the integrated MultiEthernet port that supports several Ethernet-based protocols without add-on cards. The power supply unit is configured for infeeding and fed operation, allowing surplus regenerative energy to be shared across a common DC link.
The modular control section is identified by design note B and uses the BASIC variant referenced in the type code. Feedback from motors is connected through the dedicated IndraDyn Hiperface/EnDat 2.1/2.2 encoder interface, which supports feedback devices used with compatible servo motors. Cell-level commands can be exchanged over PROFIBUS for integration with higher-level automation systems. Functional safety is provided by integrated STO (Safe Torque Off) and SBC (Safe Brake Control), allowing torque shutdown and brake control without external relays.
