Description

The REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW is a highly advanced digital servo drive from Bosch Rexroth’s IndraDrive Cs platform, representing the pinnacle of precision motion control technology. This specific variant is a single-axis, cabinet-mounted drive module designed to control synchronous servomotors with exceptional accuracy and dynamic response. The complete ordering code reveals its configuration: it features a Safety-on-Board safety interface (SE), an EtherCAT communication interface (EN2), and is equipped with the firmware option (FW) for advanced motion control functionalities. The REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW is engineered to be the intelligent core of high-performance automation systems, translating control commands into precise electrical power for servomotors, thereby enabling complex motion sequences with minimal error and maximum efficiency.

As a integral component of Rexroth’s system-oriented approach, this drive is designed for seamless integration into larger IndraDrive systems, often working in tandem with other axes and a central motion logic controller (MLC). Its value proposition lies in its ability to deliver ultra-precise control over speed, torque, and position, which is critical for applications requiring high throughput, repeatability, and quality. The REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW is not just a power amplifier; it is a sophisticated control node that processes complex motion commands locally, offloading the central PLC and enabling highly synchronized multi-axis applications. This makes it an indispensable solution for modern machinery in packaging, printing, robotics, and assembly automation.

Technical Specifications

Main Features and Advantages

Integrated Safety and Advanced Connectivity: The REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW stands out with its built-in Safety-on-Board (SE) functionality, which allows it to implement safety functions like Safe Torque Off (STO), Safe Stop 1 (SS1), and Safe Operating Stop (SOS) without requiring additional external safety relays. This integrated safety reduces wiring complexity, panel space, and cost while enhancing system reliability. Its primary EtherCAT (EN2) interface provides a high-speed, deterministic fieldbus connection, enabling seamless integration into real-time automation networks. This allows the drive to function as a precise motion slave within a larger system, achieving nanosecond-level synchronization with other axes and the master controller for exceptionally coordinated motion.

Superior Performance and Dynamic Response: Equipped with Rexroth’s High Dynamic Current Control (HDCC) technology, this drive delivers exceptionally precise and rapid current control, resulting in smoother motor operation, higher efficiency, and reduced heating. The high bandwidth enables it to respond instantly to load changes and disturbances, maintaining setpoint accuracy even under varying conditions. The inclusion of the advanced firmware (FW) unlocks a comprehensive suite of motion control capabilities, including electronic gearing, cam profiling, and flying saw applications, which can often be executed directly within the drive itself. This distributed intelligence architecture offloads the central controller, reduces network load, and allows for more complex and responsive machine behavior.

System Integration and Diagnostics: A key advantage of the REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW is its native design within the IndraDrive system. It can be combined with other Cs modules to create a multi-axis cabinet solution with a shared power supply and cooling system, optimizing space and efficiency. Comprehensive diagnostic capabilities are accessible through Rexroth’s IndraWorks software suite, providing deep insights into drive status, performance data, and maintenance requirements. This facilitates proactive maintenance, quick troubleshooting, and minimizes machine downtime, ensuring maximum productivity and longevity of the automation system.

Application Field

The REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW is engineered for high-precision automation tasks across a diverse range of industries. In packaging machinery, it is indispensable for controlling the precise start-stop motions of form-fill-seal machines, the registration control on continuous motion wrappers, and the positioning of robotic pick-and-place units. The drive’s ability to execute complex cams and gears electronically makes it perfect for synchronizing various axes in a packaging line, ensuring perfect product handling at high speeds. In printing and converting equipment, its precise registration and tension control capabilities are critical for maintaining print quality and preventing web breaks or wrinkles.

The robotics industry heavily utilizes this drive for controlling individual joints in articulated robots, where its high bandwidth and torque control enable smooth, accurate, and fast motion paths. In automated assembly and test systems, the REXROTH CSH01.1C-SE-EN2-NNN-NNN-NN-S-XP-FW provides the precise positioning needed for inserting components, performing screwdriving tasks, or moving products through various test stations with micron-level repeatability. Its integrated safety features also make it a preferred choice for applications where humans and robots may share a workspace, as it can quickly and safely halt motion according to safety protocols.
