Product Description:

The CSH01.1C-ET-ENS-NNN-NNN-NN-S-XP-FW is a modular controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It manages communication, I/O, and feedback processing so servo axes and peripheral devices remain synchronized during automated production. The unit incorporates built-in Ethernet interfaces and a single-line display, enabling parameter access and network exchange without external supervisory hardware. In a compatible drive system, it serves as the central control section between the machine network and connected motion hardware.

The control electronics draw a base power of 7.5 W, so the board adds only a minor thermal load to the low-voltage supply. During power-up, the unit experiences an inrush current of 4 A for an interval of 100 ms; circuit protection and precharge components must tolerate that transient. Multi-Ethernet capability is implemented through a 100 Mbit port that follows the 100Base-TX standard and supports cable runs up to 100 m, allowing placement at the far end of large production lines. The TTL input stage accepts position latches at up to 400 kHz, which suits high-speed registration and measurement tasks. The single-line control panel and the reserved power for the Multi-Ethernet section support local operation and network communication without added interface hardware.

The differential input path presents 120 Ω of resistance, matching typical RS-485 networks and minimizing signal reflections over long wiring. Integrated encoder support supplies up to 500 mA at 11.6 V, enough for standard rotary or linear feedback devices, and a separate encoder evaluation budget allows SinCos or TTL signals to be processed without external conditioners. The serial maintenance port permits links up to 15 m and reaches a throughput of 115 kBaud for parameter downloads. This arrangement allows feedback devices and maintenance access to be handled directly at the controller, reducing the need for separate signal-conversion modules in the cabinet.
