Product Description:

The CSH01.1C-S3-ENS-NNN-NNN-S2-S-XP-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It serves as the central processing module inside multi-axis drive racks, interpreting motion commands, scaling feedback signals, and issuing set-points to servo inverters. By combining high-speed bus links with integrated safety, the unit streamlines coordinated positioning tasks in automated packaging, handling, and assembly stations, keeping each axis synchronized with upstream PLC directives.

At the signal level, each analog input presents an impedance of 160 kΩ, preventing strain on fragile transducer outputs. The 12-bit converter maps these inputs in steps of 1.23 mV/inc, delivering fine-grained process data to the motion kernel. Two analog outputs can source up to 1 mA apiece at a fixed reference of 5 V, which is suitable for drive torque commands or external instrumentation. Internal logic and fieldbus circuitry draw just 7.5 W, minimizing power dissipation and allowing the board to sit in compact control cabinets without auxiliary cooling. SERCOS III is the primary control communication layer, so real-time telegrams share position, velocity, and diagnostic content across the machine network.

Eight digital outputs deliver up to 500 mA per channel, while a relay contact rated at 24 V DC and 1 A switches auxiliary actuators. An inrush limiter protects the supply as the module energizes, capping startup current at 4 A. Watchdog logic truncates any control strobe longer than 100 ms to guard against runaway commands. Motion feedback is handled through the IndraDyn, HIPERFACE, and 1 Vpp encoder interface, enabling absolute or incremental position tracking. An RS-232 port supports cable runs up to 15 m at 115 kBaud. Network diagnostics pass through the S3 port, which uses an RJ-45 (8-pin) connector and operates on the 100Base-TX Ethernet standard. Safe Motion technology embeds velocity, position, and stop monitoring functions that comply with machine safety requirements.
