Product Description:

The CSH01.1C-ET-ENS-EN2-NNN-L1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a configurable automation controller, it hosts motion logic, network interfacing, and encoder evaluation in a DIN-rail footprint. Within an IndraDrive modular system, the unit processes feedback from primary and secondary encoders and issues torque or velocity commands to the attached power section, making it a central component for coordinated multi-axis machinery in packaging, printing, and general factory automation.

The housing measures 241 × 49.5 × 103 mm, so it occupies a single slot beside other electronics and keeps wiring paths short. For plant networks, an integrated Ethernet interface supports the 100Base-TX physical layer and is presented on an 8-pin RJ-45 jack, which allows direct connection to PLCs or supervisory PCs. The controller exchanges real-time data through the MultiEthernet master stack, enabling protocol selection such as Sercos over EtherNet/IP without additional hardware. The controller supplies power for primary position feedback, and up to 500 mA of current can be provided to an IndraDyn, Hiperface, 1 Vpp, or TTL encoder so that installations remain within voltage tolerance. The front bezel carries a standard control panel for parameter entry and diagnostics.

The encoder rail delivers a stable 12 V logic supply, while the secondary feedback channel offers 350 mA at 5 V for EnDat 2.1, 1 Vpp, or TTL sensors; both channels include automatic short-circuit monitoring. Functional safety is handled through a D-Sub 9-pin female connector that implements a starting lockout, and the circuit relies on a 24 V / 1 A relay together with a 24 V, 3 mA input to satisfy Category 0 stop requirements. This arrangement provides hardware-level motion disable for basic stop and lockout functions.
