Product Description:

The CSH01.1C-PL-ENS-NNN-MD2-S2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted with compatible power modules, it interprets encoder feedback, evaluates discrete inputs, and issues drive commands so that servo axes and auxiliary devices remain synchronized within an automation cell. It serves as the logic core between higher-level PLCs and the drive inverter stage, handling motion profiles, diagnostic reporting, and local I/O tasks that require deterministic operation.

Overall energy demand is modest because the board requires only 7.5 W during normal operation, although an inrush current of 4 A must be available when the rack is first energized. The ENS interface supports incremental encoders by supplying a regulated 11.6 V at up to 500 mA, and its 12-bit conversion depth provides suitable resolution for position and velocity capture. Electrical loading on the feedback pair is limited by an input resistance of 120 Ω, and the channel can accept TTL signals at frequencies up to 400 kHz. Pulse-train commands on the PL channel use a D-Sub 37-pin header, while both the PL and MD2 connections provide 16 inputs and 16 outputs. For distributed sensors and actuators, the MD2 section is arranged in two input groups and four output groups, and each output can sink up to 0.5 A without an external relay.

Serial diagnostics are available through RS-232, allowing direct communication with connected service equipment or supervisory devices. The serial cable can extend up to 15 m, and transmission rates can reach 115 kBaud when the installation is arranged within those limits. Encoder pulse widths of up to 100 ms can be captured without timeout, which helps the control section interface with slower pulse sources as well as faster feedback devices. The balanced local I/O layout also helps separate fast sensor signals from inductive loads across the available MD2 output groups.
