Product Description:

The CSH01.1C-SE-ENS-EN1-MD1-L1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Inserted into an IndraDrive stack, it supervises axis motion, handles encoder feedback, and links the drive to plant networks, making it a key component for coordinated positioning tasks in automated machinery. It is installed in control cabinets where space, heat dissipation, and modularity are critical. Its function is focused on the control layer, so it works with the surrounding drive hardware rather than serving as a standalone power unit.

Its control communication channel is SERCOS II, carried over fiber optic cables, which provides the deterministic timing needed for synchronized multi-axis moves. Control electronics consume only 7.5 W, supported by an internal supply of 11.6 VDC that can deliver up to 500 mA. A single-line display and a standard control panel allow local parameter entry and fault viewing without adding separate interface hardware. Primary feedback is processed through standard encoder evaluation, while a secondary interface reads resolver and HSF signals to accommodate mixed feedback architectures. The board also provides an expansion path for digital I/O, so additional sensors and solenoids can be wired directly in the drive cabinet.

The I/O slot supports 12 additional inputs and 8 additional outputs, allowing direct machine interlocks, valve commands, or light-curtain acknowledgments without routing every signal through the higher-level PLC. For high-speed reference pulses, the TTL capture channel operates up to 400 kHz, which suits linear scales and high-count encoders used on fast-moving axes. Resolver feedback is excited at a 4 kHz carrier with an 18.2 Vpp amplitude for stable sine-cosine generation. The embedded safety circuit enforces a Starting Lockout that disables power-enable signals until reset conditions are met. This helps prevent unexpected restart behavior after a stop condition has occurred.
