Product Description:

The CSH01.1C-PB-EN2-EN1-NNN-S2-S-XP-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for IndraDrive power modules, it serves as the central processor that links a servo axis to plant networks, interprets encoder signals, and executes safety functions required in automated machinery. By merging PROFIBUS fieldbus, dual-channel feedback acquisition, and integrated Safe Motion features, the board supports precise speed, position, and torque regulation in assembly lines, packaging machines, and material-handling equipment.

The communication layer is handled through the dedicated PROFIBUS-DP interface, allowing cyclic data exchange with the PLC at up to 12 Mbit/s. This bus is routed to a D-Sub, 9-pin female connector that is labeled X30, simplifying wiring inside the cabinet. For the safety circuitry, the card expects a logic supply of DC 24 V and can drive safety outputs up to 0.5 A; these circuits are governed by the integrated Safe Motion technology, which monitors speed and position and can disconnect torque when predefined limits are exceeded. These functions support network communication and safety monitoring inside the drive.

Feedback handling is divided across two encoder channels. Channel 1 supports EnDat 2.1, 1 Vpp, and 5 V TTL formats; its HSF circuit draws 250 mA from an internal 8 V source, with signal bandwidth tailored for digital encoders. Channel 2 accommodates resolver feedback and an auxiliary HSF interface; it is powered from 5.0 V and can deliver 350 mA while driving a 35 Ω load. To preserve signal integrity, the high-speed filter on this channel imposes a cutoff frequency of 100 kHz, whereas resolver inputs are limited to 18 kHz. These electrical limits ensure reliable position capture during rapid axis movements without saturating the analog front end or introducing phase delay to the control loop.
