Product Description:
The CSB01.1C-S3-ENS-EN1-NN-S-NN-FW is a control section designed by Bosch Rexroth Indramat for integration into the CSB Drive Controllers series. When seated in a multi-axis drive rack, this module interprets network commands, conditions encoder feedback, and issues pulse-width-modulated setpoints to the associated power stage. By executing these real-time tasks, the board links machine-level motion programs with the servo mechanics that position tooling, conveyors, or pick-and-place heads in automated cells.
High-speed fieldbus connectivity is based on SERCOS III, and the RJ-45, 8-pin port supports full-duplex transmission over standard industrial cabling. The onboard PHY also accepts copper Ethernet at 100Base-TX, allowing deterministic telegram exchange with cycle times down to 1000 µs. Discrete machine states are sensed through one optically isolated digital input rated at 24 V, 3 mA, while interlock, fault, or drive-ready information can be forwarded over a sourcing digital output that delivers up to 24 V, 0.5 A. For service or diagnostics, the card carries a maintenance port that communicates via RS232, enabling parameter adjustments from a computer without occupying the real-time network.
Feedback processing is divided between an ENS interface for primary position data and an EN1 channel reserved for secondary sensing. The EN1 channel provides Hall sensor excitation at 8.0 V DC and can energize a resolver with a carrier of 18.2 Vpp AC at 4 kHz, supporting precise angle calculation over shielded motor cables. The ENS rail is buffered by an internal supply that can source up to 500 mA, which is suitable for multi-turn absolute encoders with LED-based status indicators. An auxiliary relay contact rated at 24 V DC, 1 A is available for drive-enable chains, giving machine builders a galvanically separated method to control power contactors when the controller reaches a safe operating state.
