Product Description:
The CSH02.1B-CC-EC-EC-L3-DA-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. As a compact motion and logic controller, it supervises drive axes, field devices, and peripheral sensors to execute precise sequencing in industrial automation cells. The unit sits between higher-level PLCs and servo inverters, translating motion commands, monitoring feedback, and acting as the coordination hub for the machine segment it controls. It also manages command flow and status exchange across the local machine section so motion tasks and device responses stay aligned during operation.
This variant governs 1 drive axis and exchanges cyclic setpoints through a Sercos III Master interface, which supports synchronized positioning with low jitter. The primary encoder port can deliver regulated excitation levels of 5 V, 12 V, allowing the controller to accept both TTL and HTL feedback devices without external power splitters. Application programs are downloaded across an engineering channel that uses 100Base-TX signaling and terminates on a standard RJ-45, 8-Pin jack; this link supports cable lengths up to 100 m, so cabinets can be placed with more flexibility on the plant floor. The separation between the motion network and the engineering connection helps keep real-time control traffic stable during diagnostics and program transfer.
Functional safety is addressed by the integrated Safe Torque Off circuit, which removes drive energy in less than a drive cycle when triggered by an external channel. The controller requires firmware version FWA-INDRV*-MPx-18VRS or later, and lower revisions are rejected during startup to avoid runtime mismatches. Local process signals are wired directly to the unit through 11 DI, 5 DIO, 3 AI, 2 AO on the base board, while an optional digital and analog I/O module adds more channels for machine-side expansion without rerouting cables to a remote rack. This onboard I/O mix allows nearby sensors and actuators to be connected directly at the controller for compact machine layouts.
