Product Description:

The CSH02.1B-ET-EC-EM-L3-DA-NN-FW is a motion and I/O controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit mates with IndraDrive power sections to command servo or spindle hardware and handles position, velocity, and diagnostic tasks for compact industrial automation stations. By concentrating processing and fieldbus links on one card, it simplifies cabinet layouts and provides deterministic control for a single drive axis in material handling, packaging, and assembly cells.

Designed for precise axis regulation, the controller is rated for single-axis operation and communicates with higher-level PLCs through a Multi-Ethernet interface that supports real-time variants such as EtherNet/IP or PROFINET. Its absolute position channel supports the SSI format, while selectable emulation modes allow incremental feedback when legacy devices must be retrofitted. Two analog monitor channels sample current at 12-bit resolution and voltage at 14-bit resolution, enabling fine scaling of torque or speed commands. Sensor heads connect to the multi-encoder interface, and motion and service wiring are routed through the Et connectors X22 P2 and X23 P1 plus the Da terminals X37 and X38. The Em connector is a 15-pin D-Sub male plug reserved for auxiliary encoder signals.

For actuator and signal lines, the digital outputs can source up to 500 mA, and each switching event is executed within 200 µs, which is fast enough for responsive camming or electronic gearing. Safety is built in through the STO function, and this torque-removal channel is routed to connector X49 and energized by a control supply of 24 V. Additional digital and analog channels can be added through the I/O extension port when more feedback or valve signals are needed. Continuous absolute and incremental data can coexist because the emulation and multi-encoder resources share the same internal timing architecture without oversampling errors.
