Product Description:

The CSH01.3C-S3-EN1-EN2-CCD-NN-S-NN-FW is a single-axis control section supplied by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive modular drive stacks, it handles sequence logic, axis interpolation, and local signal processing for automated machinery. By combining high-speed fieldbus links with onboard analog and digital I/O, the unit positions servomotors, evaluates sensors, and exchanges data with higher-level PLCs in real time.

This control section offers 1 analog input for reference or feedback signals and 2 analog outputs for drive-level setpoints, while the hardware totals 4 combined I/O points that can be freely mapped inside the IndraWorks project. Two dedicated probe inputs capture edge-triggered position marks with a maximum switching frequency of 16 kHz, ensuring deterministic latching during fast motion. Fieldbus traffic is handled by Sercos III, which serves simultaneously as the master and cross-communication channel for velocity, torque, and diagnostic telegrams. A pair of digital outputs is rated at 24 VDC, 0.5 A, giving enough current to energize contactors or signal lamps without an auxiliary relay. For service access, the board exposes 1 RS232 port, allowing terminal access to parameter lists and diagnostics.

Position feedback flexibility comes from an HSF resolver interface on Encoder 1 and an EnDat2.1 multi-format input on Encoder 2 that also accepts 1 Vpp and 5 V TTL signals. One normally open relay contact is included, and the circuit can switch up to 30 VDC, 1 A for ready or fault indication. The module is housed in a slimline case that measures 241 mm in height, 103 mm in width, and 49.5 mm in depth, allowing dense mounting inside drive cabinets. Despite its compact form, it maintains internal spacing through careful PCB layering and surface cooling channels.
