Product Description:

The CSH01.1C-S3-ENS-EN2-EN2-NN-S-NN-FW is a single-axis control section built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power unit, it processes fieldbus data, encoder signals, and analog references to command servomotors or spindles in industrial automation cells. By merging communication, feedback evaluation, and drive logic on one plug-in card, the unit streamlines cabinet space and simplifies wiring in packaging machines, material-handling gantries, and machining centers.

Its analog channel supplies up to 1 mA, which is suitable for position or torque references when a drive must interoperate with legacy controllers. The stage can drive loads down to 5 kΩ without signal distortion, and it holds a nominal swing of 5 V for easy interfacing with standard PLC analog inputs. Base electronics draw only 7.5 W, limiting heat generation inside densely packed drive stacks, but the capacitors admit an inrush of 4 A during power-up, so line fusing must accommodate that transient. Network cabling terminates on a RJ-45, 8-pin jack, allowing connection with common Ethernet cords.

Real-time data exchange occurs over SERCOS III, and the physical layer follows IEEE 802.3, giving deterministic motion control on standard Ethernet infrastructure. For secondary encoder supply, the En2 port delivers 5.0 V at 350 mA and tolerates a line impedance of 35 Ω, matching low-energy linear encoders. The Ens header can source 11.6 V at 500 mA with 120 Ω input resistance to power inductive sensors, while the card simultaneously accepts IndraDyn, HIPERFACE, or 1 Vpp feedback on channel one and EnDat 2.1, 1 Vpp, or 5 V TTL feedback on channels two and three. These resources let one controller support multiple feedback formats and sensor supply rails without external interface modules.
