Product Description:

The CSH01.1C-PB-EN2-EN2-NNN-L2-S-NN-FW is a plug-in control section released by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in drive systems, this card supplies axis processing, fieldbus communication, and I/O conditioning so that servo drives follow commands from a central machine program. It translates motion profiles into real-time signals for power modules and captures position feedback for tight speed and position regulation. Integrated encoder evaluation and built-in safety functions make the unit suitable for packaging, handling, and other general-purpose machinery.

Two differential analog channels accept setpoints and have an input resistance of 160 kOhm. Their scaling is resolved at 1.23 mV/Inc, which allows fine adjustment of pressure, tension, or velocity references. The board retransmits process data with an analog output that sources up to 1 mA at a nominal 5 V, while discrete loads are switched by transistor outputs rated for 0.5 A. Motion commands and diagnostics move over the PROFIBUS interface, reducing cabinet wiring when several axes are networked. Internal logic and encoder processing draw only 7.5 W, which helps limit heat buildup, and four configurable digital points sample machine sensors at 3 mA input current.

Startup demand is kept in check by an inrush limited to 4 A, easing requirements on upstream fusing. Two probe inputs capture edge events with 1 µs timing accuracy, and the dual EN2 encoder interfaces, each supplied with 5 V, return position from incremental or sine-cosine transducers. This arrangement lets the control section handle feedback and registration tasks on compact multi-axis machines. Functional safety is handled internally through Safe Torque Off, allowing drive enable to be removed without additional external relays.
