Product Description:

The CSH02.1B-ET-EC-NN-S4-NN-NN-NW is a motion-logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a central node inside an automation cell, it coordinates drive axes, manages safety supervision, and exchanges real-time data with higher-level PLCs through integrated network ports. By executing motion-control functions and cyclic position loops on board, the unit reduces load on external IPCs and streamlines machine wiring in packaging, material-handling, and assembly equipment. This arrangement lets one controller handle both coordination and response tasks close to the connected drives.

Its networking layer is based on Multi-Ethernet, allowing the same hardware to join Sercos III, EtherCAT, EtherNet/IP, or PROFINET IO domains without cabling changes. Motion telegrams move through a 250 µs communication cycle, and torque commands are refreshed every 62.5 µs current cycle; this high update rate supports precise synchronization of multiple drives. The velocity regulator closes at 125 µs, while an internal position loop uses the same 250 µs sample time as the communication layer. For discrete sensing, the controller provides 11 digital inputs plus five individually configurable digital I/O ports, allowing direct connection of switches, sensors, and interlock signals. Three user-accessible option bays accept expansion cards, and these 3 optional slots can host additional encoder, fieldbus, or memory modules. An EC module draws only 1.1 W, which keeps added power demand low during continuous operation.

Analog feedback and probing functions are handled separately; two ±10 V channels deliver setpoints through 2 analog outputs, while edge detection for registration marks is performed by 2 probe inputs. Axis safeguarding is integrated through the Safe Motion interface, enabling SIL-rated stop and monitoring functions without external relays. Application-specific capabilities can be added through the ET module, which requires just 2.7 W of DC power, and an S4 diagnostics board adds 2.5 W. The chassis also preserves a dedicated real-time Ethernet port so network traffic can remain separate from the analog, digital, and safety resources during coordinated motion.
