Product Description:

The CSB01.1C-ET-ENS-MA1-NN-S-NN-FW is produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. It acts as the control section in an IndraDrive system, translating motion commands from a plant-level PLC into precise current, velocity, and position loops for connected servo hardware. Within automated cells, the unit supervises feedback, edits trajectory data, and reports diagnostics to the higher-level system, supporting consistent throughput in packaging, handling, and machining stations.

Logic electronics run from a DC 24 V rail, and the board dissipates only 8 W during normal operation, simplifying cabinet cooling. Signal conditioning starts with 2 differential ±10 V, 12-bit analog inputs that accept external setpoints, while a matched pair of 2 ±10 V, 12-bit analog outputs feeds transducers or drives secondary actuators. For discrete wiring, the base layer offers 8 DI, 3 DO, and 1 relay for basic machine signaling, and each channel is debounced for plant-floor switching noise. High-level communication is handled through the Multi-Ethernet port, allowing EtherNet/IP, PROFINET, or EtherCAT to be selected without hardware changes. An optional Analog I/O Extension module can be installed in the designated slot to expand the continuous analog channel count.

Position control uses an encoder interface supporting IndraDyn, HIPERFACE, 1 Vpp, and 5 V TTL, so absolute or incremental feedback reaches the processing core without converters. The port delivers up to 300 mA encoder current for high-resolution sensors. Field devices such as probe switches draw power from a DC 19 to 30 V I/O supply, which helps isolate them from logic lines and reduce conducted noise. The controller limits start-up demand to 4.5 A for 110 ms and includes one Type 2 probe input and one Type 3 probe input for edge capture during timing tasks. It has no integrated safety technology, so external safety relays or drives must handle emergency stop functions.
