Product Description:

The CSB01.1C-S3-ENS-ENS-L2-S-NN-FW is a drive controller module produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. Intended for servo applications in packaging, handling, and processing equipment, the unit executes real-time motion commands, supervises feedback, and issues gate signals to a connected power section. This control arrangement separates command processing from the external power stage, which helps keep the axis electronics compact in modular drive systems. By pairing standardized network communication with integrated safety inputs, it helps machine builders shorten wiring runs and maintain deterministic axis control on factory floors.

It is classified as a Single-Axis controller, so one motor channel is processed per board, which simplifies configuration in decentralized stations. Field communication relies on Sercos III, a deterministic Ethernet-based bus that delivers cyclic command and status data with sub-millisecond jitter. The bus enters the electronics through the designated X8 (On-Board) slot, eliminating daughter cards and conserving cabinet space. Position feedback wiring is accepted through 2 × D-Sub 15 female connectors, which carry incremental, SinCos, or multi-turn encoder signals while keeping shielding continuous up to the PCB. These encoders draw power from the integrated rail, and the controller can source up to 11.6 VDC at 500 mA, allowing two high-resolution sensors to operate simultaneously without external supplies.

Network diagnostics share the same physical layer as the motion bus. The embedded Ethernet transceiver supports 100Base-TX signaling and routes through an 8-pin RJ-45 connector, so standard CAT5e shielded ITP patch cables can be used between the controller and a switch. Functional safety is built in through Safe Torque Off, which disconnects drive power by dual-channel logic rather than relying on contactors. When the STO inputs are driven with 24-volt, 3 mA signals on the safety plug, the power stage meets the SIL3 / Cat. 3 PL e integrity level, permitting its use on axes where hazardous motion must be prevented without adding external relays.
