Product Description:

The CSH01.1C-SE-ENS-EN1-MA1-S2-S-XP-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This module serves as the central processing and interface layer within IndraDrive systems, coordinating motion axes and safety functions in industrial automation cells. By handling high-speed fieldbus communication, analog I/O processing, and integrated safety, it links servo drives to higher-level PLCs while executing drive-based logic that maintains deterministic cycle times on assembly lines, packaging stations, and material-handling equipment.

During normal operation, the controller dissipates 7.5 W of base power, a low thermal load that simplifies cabinet ventilation. When line power is applied, it momentarily draws an inrush of 4 A for 100 ms, so upstream breakers and wiring must accommodate that pulse. Motion commands reach the section over the SERCOS II fiber-optic ring, and its channel streams data at 16 MBaud, enabling synchronized control of multiple drives. The MA1 option card provides two analog input channels and two analog output channels, and both directions are digitized at a granularity of 5 mV per increment to support sensor scaling and actuator setpoints. Safe Motion technology runs on dedicated logic inside the unit, enabling certified functions such as safely limited speed without external relays.

Feedback supplies are routed through the ENS and EN1 connectors. The ENS rail offers 11.6 V at 500 mA, powering single-turn or multi-turn encoders mounted on servo motors. For high-speed resolver feedback, the EN1 rail sources 8 V at 250 mA and excites the resolver with a carrier of 4 kHz at 18.2 Vpp, ensuring clean sine-cosine signals over long cables. These dedicated supplies isolate sensor returns from the drive's internal logic and maintain reference stability even during network resets. The paired rails support mixed encoder topologies so the controller can process absolute position data and stable resolver tracking within the same axis group.
