Product Description:

The CSH01.1C-ET-EN2-EN2-NNN-NN-S-NN-FW is a motion-logic control section manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in modular drive racks, it coordinates multiple servo axes, routes high-speed fieldbus traffic, and handles local I/O for automated packaging, printing, and material-handling equipment. By executing deterministic command sequences next to the power stage, it frees the central PLC and keeps positioning cycles synchronized to real-time machine events.

Its electronics consume just 7.5 W, limiting thermal load inside the cabinet. A single Multi-Ethernet interface offers EtherNet/IP, PROFINET, EtherCAT, and Sercos III connectivity without extra hardware. The module provides 4 configurable I/O channels; an input is treated as logic high once line voltage reaches 15 V, while sourcing outputs can deliver up to 500 mA to small relays or lamps. Two encoder ports accept EnDat 2.1, 1 Vpp, or 5 V TTL feedback, and the analog monitor track supplies +1 mA over a 0 to +5 V span for process supervision. Dedicated ASICs inside the control section handle position-latch logic, calculate velocity loops, and generate PWM set-points for connected power modules, minimizing bus latency when cycle times tighten.

Power-up surges are limited to 4 A for 100 ms, preventing nuisance tripping of upstream protections. After startup, command toggling can reach a switching frequency of 8 kHz, and probe inputs capture registration marks within a narrow 4 µs window, supporting precise print-to-cut alignment or gear-synchronous probing. For galvanically isolated signaling, the built-in relay is rated at 24 V DC, 1 A, allowing direct control of brakes, contactors, or alarm circuits without external drivers. Self-diagnostics continuously survey board temperature and supply rails, issuing a fault telegram if operating limits are approached.
