Product Description:
The HCS01.1E-W0028-A-03-B-ET-EC-EM-S4-NN-AW is a drive controller manufactured by Bosch Rexroth Indramat as part of the HCS IndraDrive Controllers series. The unit regulates three-phase servo or induction motors in automation cells, acting as the power stage that converts plant mains into controlled motor current. It belongs to the compact HCS01 hardware line and pairs with a control section to support motion control, diagnostics, and fieldbus communication. Its compact format also suits dense cabinet layouts used in packaging, handling, and general automation equipment.
The controller accepts a supply of 3 x AC 200 to 500 V ±10%, allowing the same hardware to operate on both 230 V and 400 V networks without tap changes. Peak output capability reaches 28 A, so short acceleration bursts can be delivered without adding external choppers. Internal thermal management uses internal air cooling through an integrated blower, and the blower circulates cabinet air across the heat sink to maintain rated current at 45 °C ambient. For plant networking, the controller hosts a MultiEthernet interface, and the backplane auto-negotiates Sercos III, EtherNet/IP, EtherCAT, and PROFINET protocols. The housing carries an IP20 rating, so it is finger-safe but intended for installation inside a control cabinet.
The controller is delivered in design version 1, which matches the initial release of this platform. Encoder feedback is handled through two dedicated ports: Interface 1 accepts IndraDyn Hiperface or EnDat 2.1/2.2 encoder signals for absolute position data, while Interface 2 provides encoder emulation pulses for legacy drives. The control section specified as BASIC supports single-axis positioning and includes a local USB port for service access. The converter supports infeeding or fed operation, so it can receive energy from an upstream supply module or return energy to the DC bus during regeneration.
