Rexroth CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW System-Ready Servo Drive for IndraDrive Architecture

Rexroth CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW System-Ready Servo Drive for IndraDrive Architecture

The Bosch Rexroth CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is a high-performance control section module engineered for seamless Contextual Integration within the IndraDrive modular servo drive platform. Designed to operate as the intelligence layer of a distributed motion control architecture, this control section coordinates signal processing, communication, and axis management across multi-axis machine configurations. Its role extends beyond individual axis control — it serves as the architectural backbone that links the control layer, I/O layer, network layer, power layer, HMI layer, and execution layer into a unified, deterministic automation system.

In modern industrial automation, the reliability of a servo drive control section directly determines the consistency of the entire machine cycle. The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is built to meet the demands of high-cycle manufacturing environments where signal integrity, communication latency, and axis synchronization are mission-critical. Its SERCOS III interface enables real-time, isochronous communication with the master controller, ensuring that position, velocity, and torque commands are executed with microsecond-level precision across all connected axes.

This module is fully compatible with the IndraDrive C and IndraDrive M power section families, including the HCS02 and HCS03 single-axis inverter units and the HMV01 and HMV02 supply units. When paired with the HMS01 or HMD01 power sections, the CSH01.1C forms a complete drive unit capable of supporting both standard servo and high-dynamic spindle applications. The modular architecture allows engineers to configure single-axis or multi-axis systems with shared DC bus topology, reducing cabinet footprint and simplifying power distribution design.

From the control layer perspective, the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW interfaces directly with Bosch Rexroth IndraMotion MLC or IndraMotion MTX CNC controllers via SERCOS III, enabling centralized motion program execution with distributed drive intelligence. The drive’s onboard firmware — managed through the FWA-INDRV*-MPH firmware package — supports advanced motion functions including electronic gearing, cam profiling, and synchronous axis coupling, which are essential for packaging lines, printing machines, and precision assembly systems.

At the I/O layer, the CSH01.1C integrates with the IndraDrive I/O extension modules and supports digital and analog I/O expansion through the CDB01 drive-integrated I/O module. This allows local signal conditioning and fast interrupt-driven responses without routing every signal back to the central PLC, reducing cycle time and improving system responsiveness. For applications requiring safety-rated I/O, the module supports integration with the CSB01 safety option card, enabling STO (Safe Torque Off) and SS1 (Safe Stop 1) functions in compliance with IEC 62061 and ISO 13849.

Network layer stability is ensured through the ENS (SERCOS III) communication interface embedded in this control section variant. SERCOS III’s ring topology provides inherent redundancy — if one segment of the ring is interrupted, the network automatically reconfigures to maintain communication with all remaining nodes. This makes the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW particularly well-suited for large-scale multi-axis systems in automotive body-in-white lines, steel rolling mills, and continuous process plants where network interruption cannot be tolerated.

For the power layer, the CSH01.1C is designed to operate within the IndraDrive shared DC bus architecture. The HMV01.1R regenerative supply unit feeds the common DC bus, from which multiple HCS02 or HMS01 inverter units draw power. This topology not only reduces energy consumption through regenerative braking but also simplifies the power cabinet design by eliminating individual AC input filters for each axis. The CFL01 mains filter and the NFD03 line filter are recommended upstream components to ensure EMC compliance in sensitive industrial environments.

Long-term maintenance efficiency is a core design principle of the IndraDrive platform. The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW stores all axis parameters, firmware, and application data on the module itself, enabling rapid replacement without requiring a laptop or programming tool on the factory floor. Parameter backup and restore can also be managed via the IndraWorks engineering software, which provides a centralized project repository for all drive configurations across the machine. This dramatically reduces mean time to repair (MTTR) in the event of a module failure.

All units supplied by ZYPLC are covered by a 12-Month Warranty and undergo functional verification prior to shipment. Our inventory includes both new and professionally refurbished CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW units, with global logistics support to minimize lead times for urgent replacement requirements.

Coordinated Control System Design

The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW achieves its full performance potential when deployed as part of a coordinated IndraDrive system architecture. A typical multi-axis servo system built around this control section includes the following coordinated components:

The HMV01.1R regenerative supply unit provides the shared DC bus voltage, feeding power to multiple drive axes simultaneously while recovering braking energy back to the mains. Paired with the HCS02.1E single-axis inverter, the CSH01.1C forms a complete drive unit for standard servo axes. For high-power spindle applications, the HMS01.1N power section is the preferred pairing, offering higher continuous current ratings and enhanced thermal management.

At the network level, the IndraMotion MLC L45 motion logic controller acts as the SERCOS III master, issuing synchronized motion commands to all CSH01.1C control sections on the ring. The VCP20 or VCP25 operator panel serves as the HMI layer, providing real-time axis status visualization and parameter access for commissioning engineers. For applications requiring PLC integration alongside motion control, the IndraLogic XLC provides IEC 61131-3 programming with direct access to drive parameters via the SERCOS III interface.

The CDB01 drive-integrated I/O module expands local digital I/O capacity at each axis, enabling fast local interlocking without PLC scan cycle delays. For safety-critical axes, the CSB01 safety option card integrates directly into the CSH01.1C housing, providing certified STO and SS1 functions. Upstream power quality is managed by the CFL01 mains filter, which suppresses conducted EMI and protects the drive system from mains-borne disturbances in industrial environments.

Application in Layered Automation Systems

The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is deployed across a wide range of industrial sectors where precision motion control and system-level integration are non-negotiable requirements.

In automotive manufacturing, this control section is used in body-in-white welding lines, transfer press systems, and robotic cell servo axes, where multi-axis synchronization and fast fault response are essential for maintaining production throughput. The SERCOS III ring topology ensures that a single cable fault does not halt the entire line.

In packaging and printing, the CSH01.1C supports electronic line shaft architectures where multiple axes must maintain precise phase relationships at high speeds. The cam profiling and electronic gearing functions eliminate mechanical shafts, reducing maintenance requirements and enabling rapid format changeover.

In steel and metals processing, the module is applied in rolling mill drives, coiler/uncoiler systems, and straightening lines, where high dynamic torque response and robust communication under electrically noisy conditions are critical. The SERCOS III fiber optic option provides complete galvanic isolation in high-interference environments.

Architecture Engineering FAQ

Q1: Is the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW compatible with existing IndraDrive C power sections already installed in my machine?
Yes. The CSH01.1C control section is designed for direct mechanical and electrical compatibility with the IndraDrive C (HCS02, HCS03) and IndraDrive M (HMS01, HMD01) power section families. When replacing an existing control section, the power section remains in place and only the control module is exchanged. All axis parameters stored on the original control section can be backed up via IndraWorks and restored to the replacement unit, minimizing commissioning time. Our 12-Month Warranty covers the replacement unit from the date of shipment.

Q2: Can this control section be integrated into a mixed-protocol architecture where some axes use PROFINET and others use SERCOS III?
The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is specifically configured for SERCOS III (ENS variant) as its primary fieldbus interface. For mixed-protocol architectures, a SERCOS III to PROFINET gateway — such as the Bosch Rexroth CMP or a third-party protocol converter — can bridge the two networks at the controller level. Alternatively, Bosch Rexroth offers PROFINET-variant control sections (CSH01.1C-SE-ENP) for axes that must communicate natively over PROFINET. ZYPLC can advise on the correct variant selection for your specific architecture.

Q3: What is the recommended commissioning procedure for a multi-axis system using multiple CSH01.1C units, and how does the 12-Month Warranty apply to system-level testing?
Commissioning a multi-axis CSH01.1C system follows the standard IndraDrive startup sequence: (1) configure the SERCOS III ring topology in IndraWorks, (2) assign drive addresses and load axis parameters, (3) perform motor identification and encoder calibration for each axis, (4) execute the axis-by-axis function test before enabling multi-axis synchronization. ZYPLC’s 12-Month Warranty covers each CSH01.1C unit individually from the date of shipment. Units that exhibit functional defects during commissioning or within the warranty period are eligible for replacement or repair at no additional cost, subject to standard warranty terms.
