Product Description:

The CSH01.1C-S3-EN1-EN2-NNN-NN-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat and supplied as part of the CSH Advanced Controllers series. It is intended to mount inside an IndraDrive power unit, where it coordinates servo positioning and cyclic data exchange for automated machinery. By combining motion control, fieldbus supervision, and fast probing functions in one compact slot, the card streamlines cabinet layouts in packaging, printing, and material-handling equipment. Its role is to manage axis behavior inside the drive rather than provide motor power directly.

The controller accepts analog input swings up to ±10 V. Each input has an impedance of 160 kΩ, which reduces loading on external transducers, and a resolution of 1.23 mV for fine setpoint scaling. Two voltage outputs deliver up to 5 V / 1 mA with an incremental step of 19.5 mV for drive reference or actuator bias. Internally, the module draws 7.5 W, which helps limit thermal rise inside the drive stack. Motion commands and parameter data are exchanged over SERCOS III, ensuring phase-accurate synchronization among multiple axes and consistent timing between the control section and the connected power stage. The fast capture inputs can process pulse widths up to 100 ms for camming and registration tasks.

Auxiliary electrical interfaces are routed through a shielded RJ-45 connector that carries the 8-pin service bus. Twelve sourcing inputs accept 24 V / 3 mA signals, while six high-side outputs switch 24 V loads up to 0.5 A. An inrush limiter restricts startup draw to 4 A, which helps protect shared cabinet supplies during power-up. Encoder slot one works with resolver or HSF feedback, and slot two supports EnDat 2.1, 1 Vpp, or 5 V TTL sensors through a regulated sensor supply. The probe channel stamps events with 1 µs accuracy, so position capture stays closely aligned with mechanical triggers. This range of feedback and I/O options suits high-speed assembly, labeling, and cell interlock applications.
