Product Description:

The CSH01.1C-S3-ENS-NNN-NNN-NN-S-XP-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power module, it executes axis interpolation, manages local inputs and outputs, and forwards real-time data to higher-level PLCs. Its role is to provide precise motion coordination in industrial automation assemblies such as pick-and-place stations, converting lines, and automated storage systems. Through separate plug-in modules, the board accepts encoder feedback, analog process variables, and fieldbus telegrams. Because it is mounted directly on the drive, signal processing and axis control remain close to the connected motor and feedback hardware during operation.

The analog front end presents an input resistance of 160 kΩ, so sensors see minimal loading and noise pickup stays low across long harnesses. Its 12-bit converter discriminates voltage changes in steps of 1.23 mV/inc, while the digital-to-analog stage issues setpoints with 19.5 mV/inc granularity, allowing tight speed or torque regulation. At initial energization, the card draws a base inrush of 4 A for the specified pulse duration, after which the electronics settle to only 7.5 W of continuous demand. In multi-axis machines, the power supply and cabinet cooling must account for both the startup load and the steady-state draw.

High-speed deterministic messaging is carried over SERCOS III, implemented on the onboard ASIC and accessed through an RJ45, 8-pin port. The logic side can drive status lamps, relays, or brake solenoids with an aggregate digital load of 500 mA, and it powers incremental or absolute encoders from a dedicated rail rated at 11.6 V. An auxiliary interface compliant with 100Base-TX supports service and diagnostic traffic without disrupting motion-control bandwidth. This separation allows network access for setup and fault review while the real-time motion channel remains available for control tasks.
