The R911378003 (HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-FW) is a Bosch Rexroth HCS01 series digital drive controller designed for operation with a three-phase AC mains voltage of 200 to 500 V (±10%). It features a device peak current of 8 A and uses air for internal cooling through an integrated blower with heat dissipation via top-mounted outlets. The controller includes Multi-Ethernet communication, an integrated multi-encoder interface supporting IndraDyn, Hiperface, and EnDat 2.1/2.2 protocols, and supports optional safety modules for Safe Torque Off (STO) and Safe Brake Control (SBC) functions. The enclosure complies with IP20, and the control section design is BASIC (B). Firmware must be specified and ordered separately.

Frequently Asked Questions

How does the HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-AW implement safety braking?

The unit issues a mechanical brake command through its Safe Brake Control channel while concurrently disabling torque electronically. Together these features ensure a physical hold under fault conditions and reduce reliance on external braking hardware for safe machine stops.

What network capability does the HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-AW provide?

It offers MultiEthernet for native integration with modern industrial networks, enabling low-latency motion command exchange and telemetry. This simplifies architecture by removing gateways and supports coordinated multi-axis control across deterministic networks.

What encoder interface is used with the HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-AW?

This model supports Hiperface/EnDat encoder protocols, providing high-resolution position feedback for precise closed-loop control. That compatibility enables fine tuning of motion profiles and reduces steady-state error in demanding positioning tasks.

What does the IP20 rating mean for HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-AW installations?

IP20 indicates protection against accidental contact and larger particles but not against moisture or fine dust ingress. Install the drive inside ventilated cabinets in clean indoor environments or add protective enclosures if used in harsher shop-floor conditions.

How should firmware be managed for HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-AW?

Firmware is ordered separately to allow controlled selection and validation against your control topology prior to deployment. Implement staged rollouts and maintain version documentation to ensure consistent behavior and simplified troubleshooting across the fleet.

Common Misspellings

Internal Product Review

HCS01.1E-W0008-A-03-B-ET-EC-EP-L4-NN-AW combines dual safety measures for robust axis arrest while maintaining MultiEthernet connectivity. This balance of mechanical brake control and electronic torque isolation suits heavy-load applications.
