The HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW from Bosch Rexroth Indramat features MultiEthernet communication and an IP20 rating. Part of the HCS IndraDrive Controllers, it uses internal blower cooling and supports a peak current of 8 A. It operates on 3×AC 200–500 V ±10% and includes STO Safe Torque Off functionality.

It integrates IndraDyn Hiperface/EnDat 2.1/2.2 encoder support and offers encoder emulation as a backup. Firmware must be ordered separately. It pairs with the BASIC control section.

Frequently Asked Questions

How does encoder emulation work on the HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW?

Encoder emulation synthesizes position feedback when a primary encoder fails, allowing the control loop to continue operating in a degraded but safe mode. This avoids immediate process stoppage and gives service teams time to replace hardware without abrupt production loss.

What safety capability is provided by the HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW?

This unit implements Safe Torque Off to eliminate drive torque when a safety event is triggered, preventing unintended motion. That built-in safety function reduces the need for external safety relays in simple safety architectures and streamlines cabinet wiring.

How effective is the internal blower cooling in the HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW?

The integrated blower establishes directed airflow over power electronics to maintain junction temperatures within rated ranges during continuous operation. That thermal management increases component longevity and reduces thermal derating in sustained duty cycles.

How does the IP20 enclosure affect deployment of the HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW?

The IP20 rating protects against solid ingress while preserving ventilation for cooling, making the unit suitable for indoor control cabinets. For harsher environments, additional protective measures are required to meet dust and moisture resilience needs.

How is firmware handling organized for the HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW?

Firmware is supplied as a separate order item so integrators can select versions matched to application requirements and safety validation procedures. That approach enables controlled updates and ensures firmware revision management aligns with machine certification cycles.

Internal Product Review

The Bosch Rexroth's HCS01.1E-W0008-A-03-A-ET-EC-EM-L3-NN-FW emphasizes encoder emulation as a fallback for feedback continuity. That feature reduces downtime during sensor faults by providing synthetic position feedback, enabling drives to hold control loops stable.
