Product Description:
Bosch Rexroth Indramat produces the CSH01.1C-SE-ENS-NNN-MA1-S2-S-NN-FW controller as part of the CSH Advanced Controllers series. This single-axis control unit serves as the command layer in drive systems, processing fieldbus data and encoder feedback to execute precise position and velocity loops. As the SERCOS master for connected inverters, it coordinates servo motion, manages safety functions, and provides a compact interface between higher-level PLCs and the power electronics used in industrial automation cells. Because the control section is separated from the power stage, the unit can focus on motion processing, feedback evaluation, and network exchange for one axis.
The module includes two differential ±10 V, 12-bit inputs for analog feedback and two ±10 V, 12-bit outputs for analog command signals, allowing direct interaction with transducers, potentiometers, or amplifiers. Each voltage output is limited to a 10 mA maximum sink current, so wiring can remain light. Position monitoring is supported through IndraDyn, HIPERFACE, EnDat 2.1, and 1 Vpp encoder formats. Support for these feedback types lets the controller work with both established and newer motor systems without an added interface module. The sensor interface delivers 11.6 V typical at up to 500 mA maximum, enough for absolute encoders with integrated electronics. Real-time communication uses the SERCOS bus; telegrams leave the X20 port and return on X21 over fiber or copper at up to 16 MBaud maximum. A physical depth of 103 mm keeps the unit slim for dense panel layouts, and a single-line display provides local parameter access.
For functional safety, the controller integrates Safe Motion certified to SIL2 / Cat. 3 PL d, so axis monitoring can occur without shutting down upstream PLC logic. All safety I/O is routed through a D-Sub 9-pin female connector, simplifying field wiring to light curtains or door switches. The compact footprint includes a width of 49.5 mm and a height of 241 mm, allowing adjacent drives to be mounted with minimal clearance while maintaining convection paths. This layout also helps conserve rail space in compact control cabinets where several axes are installed side by side.
