Bosch 47961-103401 IndraDrive Servo Drive Module: Industrial Data Link for HCS Series Smart Factory Systems

The Bosch Rexroth 47961-103401 is a high-performance IndraDrive servo drive module engineered for the HCS Series platform, delivering robust industrial network communication across multi-protocol automation environments. Designed to serve as a critical data link between field-level devices and upper-level control systems, this module supports seamless integration within modern smart factory architectures — from signal acquisition at the sensor layer through to real-time monitoring at the SCADA and MES level.

In today’s connected manufacturing environment, the ability to bridge diverse communication protocols without data loss or latency is non-negotiable. The 47961-103401 addresses this requirement directly, supporting EtherCAT and SERCOS III industrial Ethernet protocols that enable deterministic, high-speed data exchange between servo axes, PLC controllers, remote I/O stations, and supervisory systems. Whether deployed in a standalone servo axis or as part of a coordinated multi-axis drive network, this module ensures that motion data, fault diagnostics, and process parameters are continuously available to the control layer.

Compatibility & Integration Notes

Connected Automation Data Flow

The 47961-103401 operates at the heart of a layered industrial communication architecture. At the field level, sensors and encoders feed real-time position, speed, and torque data into the drive’s internal processing unit. This data is then formatted and transmitted upstream via the SERCOS III ring or EtherCAT segment to the motion controller — typically an IndraMotion MLC or IndraControl L-series PLC — which coordinates axis synchronization and executes the motion program.

Within a typical HCS Series drive cabinet, the 47961-103401 works alongside companion modules such as the HMV01 supply unit, which provides the DC bus voltage shared across multiple HCS02 and HCS03 drive axes. The CSB01 and CSH01 control sections plug directly into the drive power section, enabling flexible configuration of communication options and safety functions. For applications requiring expanded I/O, the IndraControl XM remote I/O system connects via EtherCAT, extending digital and analog signal acquisition to distributed field panels without additional wiring complexity.

At the HMI layer, Bosch Rexroth IndraControl VR visualization panels connect to the drive network via Ethernet, providing operators with live axis status, alarm history, and parameter access. These panels communicate with the IndraMotion controller, which aggregates drive data and presents it through a unified process view. For SCADA integration, the IndraLogic XLC soft PLC or a third-party SCADA gateway translates SERCOS III drive data into OPC-UA or PROFINET frames, making servo axis data available to plant-wide monitoring systems.

In variable-speed pump and fan applications, the IndraDrive Fc frequency converter series shares the same IndraWorks engineering platform as the 47961-103401, allowing unified parameterization and diagnostics across both servo and variable-frequency drive assets. For edge-level data aggregation, Bosch Rexroth’s ActiveCockpit industrial IoT gateway can subscribe to drive process values and forward them to cloud analytics platforms, enabling predictive maintenance workflows based on real drive operating data.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial automation is the coexistence of legacy fieldbus systems — such as PROFIBUS DP or CANopen — alongside modern Industrial Ethernet networks. The 47961-103401, as part of the IndraDrive HCS platform, supports protocol gateway configurations that allow older DKC series EcoDrive controllers and PROFIBUS-connected devices to exchange data with EtherCAT or SERCOS III segments through the IndraMotion controller’s integrated protocol translation layer. This eliminates data silos that would otherwise prevent production line transparency.

Remote monitoring and diagnostics are equally critical. The 47961-103401 supports Bosch Rexroth’s IndraWorks DS diagnostic software, which enables engineers to access drive fault logs, oscilloscope traces, and parameter sets remotely over the plant Ethernet network — without requiring physical access to the drive cabinet. Alarm events are forwarded in real time to the SCADA system, where they trigger maintenance workflows and reduce mean time to repair.

For production line scalability, the HCS Series architecture supports hot-plug axis expansion. Additional HCS02 or HCS03 drive modules can be added to the shared DC bus without powering down the entire drive line, minimizing production interruption during capacity upgrades. The 47961-103401’s network interface automatically enumerates new axes within the SERCOS III ring, making system expansion transparent to the motion controller.

All units supplied by ZYPLC undergo pre-shipment functional testing, including communication link verification, parameter upload, and fault-free power cycle confirmation. Each 47961-103401 module is shipped with a warranty terms confirmed during quotation covering manufacturing defects and communication interface failures, with availability confirmed by RFQ availability ensuring rapid dispatch to global destinations.

Industrial Connectivity FAQ

Q1: What communication protocols does the Bosch Rexroth 47961-103401 support, and is it compatible with PROFINET systems?
The 47961-103401 natively supports EtherCAT and SERCOS III industrial Ethernet protocols. PROFINET compatibility is achievable through the IndraMotion controller’s integrated protocol gateway, which translates SERCOS III drive data into PROFINET frames for integration with Siemens or other PROFINET-based SCADA and HMI systems.

Q2: What is the typical communication cycle time for this drive module in a multi-axis SERCOS III network?
In SERCOS III ring topology, the 47961-103401 supports communication cycle times as low as 62.5 µs, enabling deterministic real-time data exchange across up to 40 drive axes per ring segment. This ensures precise axis synchronization for high-speed coordinated motion applications.

Q3: Can this module be integrated into an existing SCADA or HMI system without replacing the current PLC infrastructure?
Yes. The 47961-103401 integrates with existing PLC and SCADA infrastructure through the IndraMotion controller’s OPC-UA server or via third-party protocol gateways. No replacement of existing PLC hardware is required — the drive network appears as a standard data source to the supervisory system.

Q4: What warranty and pre-shipment testing does ZYPLC provide for the 47961-103401?
Every 47961-103401 unit supplied by ZYPLC is covered by a warranty terms confirmed during quotation against manufacturing defects and communication interface failures. Prior to shipment, each unit undergoes functional testing including communication link verification, parameter integrity check, and fault-free power cycle confirmation to ensure reliable operation upon installation.
