Product Description:

The CSH01.1C-PL-ENS-MA1-MD1-S1-S-NN-FW is a modular motion-control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the command processor inside IndraDrive systems, combining encoder evaluation, PLC-type logic, and communication handling on a single board. In automated cells, the unit orchestrates torque, speed, and position loops for multiple axes, allowing coordinated movement while conserving panel space and reducing overall wiring. This arrangement also lets the drive handle local feedback processing and I/O tasks without requiring separate control modules for each axis.

Startup stresses are moderated by a core inrush current of 4 A, enabling standard circuit protection without oversizing. This surge is confined to a maximum duration of 100 ms, so protective devices return to nominal conditions almost immediately. Once energized, the controller draws only 7.5 W, limiting internal heat rise and permitting fanless cabinets. The MA1 mezzanine supplies two analog inputs and two outputs that are sampled and generated with 12-bit resolution, giving fine-grained scaling for pressure, tension, or position feedback. That analog capability supports stable signal handling when external transducers are used for process variables. Command data from higher-level electronics reaches the board through a Parallel Interface, which transfers 16-bit words simultaneously to avoid the latency of serial protocols.

The MD1 section contributes 12 digital inputs for home sensors, overtravel detection, or probe capture, and 8 high-side transistor outputs for contactor coils or stack-light segments. The digital I/O section can also manage interlocks and status signals directly at the drive level. Service laptops connect through the integrated RS-232 port, which supports a peak rate of 115 kBaud for responsive diagnostics and parameter access within the 15 m cable limit. Field wiring terminates on the S1 plug, which distributes input references and driver lines at a control level of 24 V. This standardized voltage supports predictable switching thresholds and allows shared power supplies across multiple controller cards.
