Product Overview
Bosch Rexroth CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW: Ruggedized IndraDrive Cs Servo Drive for Harsh Industrial Environments
The Bosch Rexroth CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW (Part No. R911326830) is a compact, high-performance servo drive from the IndraDrive Cs series — engineered to deliver precise motion control under the most demanding industrial conditions. Designed and manufactured in Germany to Bosch Rexroth’s exacting quality standards, this drive is built for continuous operation in environments characterized by high ambient temperatures, elevated humidity, airborne particulates, mechanical vibration, and intense electromagnetic interference (EMI). Whether deployed on a high-speed packaging line, a precision CNC machining center, or a safety-critical press control system, the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW delivers consistent, fault-tolerant servo performance that industrial engineers and maintenance teams can rely on.
The IndraDrive Cs platform is Bosch Rexroth’s answer to the growing demand for compact, cabinet-integrated servo solutions that do not compromise on capability. The CSH01.1C variant integrates the drive controller and power section into a single slim housing, reducing panel space requirements while maintaining full compatibility with the broader Rexroth drive ecosystem. Its single-axis architecture makes it ideal for distributed motion architectures where each axis demands independent, deterministic control — a configuration common in semiconductor handling, medical device assembly, and automated warehousing systems.

Comprehensive Protection Solutions
In modern industrial automation architectures, a servo drive never operates in isolation. The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is designed to integrate seamlessly within a layered control and protection ecosystem. On the motion controller side, it pairs directly with the Bosch Rexroth IndraMotion MLC L45 multi-axis motion logic controller, which coordinates trajectory planning and real-time axis synchronization across SERCOS III networks. For applications requiring integrated CNC functionality, the IndraMotion MTX micro provides a compact yet powerful path interpolation engine that leverages the CSH01.1C’s high-bandwidth current loop for sub-millisecond response.
Power quality is critical in harsh environments. The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is typically paired with a Rexroth HMV01.1E mains supply unit or a compatible HCS02 regenerative power supply, which conditions incoming AC power and manages DC bus energy recovery — reducing heat dissipation in the control cabinet and extending the service life of all connected drives. Line reactors and Rexroth NFD03 EMC line filters are recommended upstream to suppress conducted emissions in environments with heavy motor loads or frequent switching transients from variable frequency drives (VFDs).
For functional safety compliance, the drive’s integrated Safe Torque Off (STO) function interfaces directly with Pilz PNOZ X or Sick Flexi Soft safety relay modules, enabling SIL 2 / PLd machine guarding without external contactors. In cabinet builds where space is at a premium, Weidmüller KLIPPON terminal blocks and Phoenix Contact PTFIX distribution blocks provide clean, vibration-resistant signal and power termination for the drive’s I/O and feedback wiring. The drive’s SERCOS III port also supports integration with Rexroth CML65 I/O modules for distributed digital and analog I/O expansion across the machine frame.
Application in Critical Infrastructure
The Bosch Rexroth CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW has established a strong track record across the most demanding sectors of critical infrastructure. In oil and gas processing, it controls valve actuators and pump drives in upstream separation skids where ambient temperatures routinely exceed 40 °C and airborne H₂S creates aggressive corrosion risks for unprotected electronics — the drive’s sealed housing and conformal-coated PCBs provide the necessary barrier. In mining and mineral processing, it drives conveyor positioning systems and crusher feed controls where continuous vibration and coal dust ingress would rapidly degrade lesser drives; its IEC 60068-2-6 vibration rating ensures structural integrity across the full operating cycle.
In electric power generation and grid infrastructure, the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is deployed in turbine governor actuator systems and transformer tap-changer drives, where deterministic response and EMI immunity are non-negotiable. Water and wastewater treatment facilities rely on it for precise dosing pump control and sluice gate positioning, where the drive’s STO safety function satisfies the functional safety requirements of IEC 61511 process safety standards. In steel and aluminum smelting operations, it manages rolling mill gap control and coiler tension regulation — applications where microsecond-level torque response directly determines product dimensional quality and yield.
Across all these sectors, the ability to source a verified, tested replacement unit rapidly is as important as the drive’s technical specification. TOPNLMS maintains dedicated stock of the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW to support emergency breakdown scenarios, planned maintenance windows, and long-term spare parts programs for facilities that have standardized on the IndraDrive Cs platform.
Security & Quality FAQ
Q1: What does the 12-month warranty cover, and how is a claim processed?
The 12-month warranty covers all manufacturing defects and functional failures under normal operating conditions as specified in the Bosch Rexroth IndraDrive Cs documentation. If a unit fails within the warranty period, TOPNLMS will arrange a replacement or repair at no additional cost. Claims are initiated by contacting [email protected] with the order reference and a description of the fault. Typical claim resolution time is 3–7 business days for in-stock replacement units.
Q2: How is each unit tested before shipment?
Every CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW unit undergoes a pre-shipment functional verification that includes power-on self-test, firmware version confirmation, communication interface check (SERCOS III handshake), and visual inspection for physical damage. Refurbished units additionally undergo a full load cycle test and insulation resistance measurement. A test report is available upon request for quality-critical procurement processes.
Q3: Is this drive compatible with my existing Rexroth or third-party control system?
The CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW is natively compatible with all Bosch Rexroth IndraMotion MLC and MTX controllers via SERCOS III. It is also compatible with third-party PLCs and CNCs that support SERCOS III or EtherCAT master functionality, including Siemens SIMOTION, Beckhoff TwinCAT, and Mitsubishi MELSEC iQ-R series (via appropriate gateway configuration). Please provide your existing controller model when inquiring so our technical team can confirm the integration path.
Q4: Can TOPNLMS support long-term supply for facilities with multiple CSH01.1C units?
Yes. TOPNLMS operates a dedicated industrial automation spare parts program for facilities that have standardized on specific drive models.
