Product Description:

The CSH01.1C-SE-ENS-EN1-EN2-NN-S-NN-FW is a single-axis controller board produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive modular rack, it executes real-time motion commands, processes sensor feedback, and coordinates drive functions for industrial actuators and servo motors. By combining encoder evaluation, fieldbus communication, and onboard I/O, the board serves as the central automation interface between higher-level PLCs and the power electronics that energize motor windings.

The analog command interface accepts signals within ±10 V, and its input resistance of 160 kΩ minimizes load on upstream transmitters while preserving signal integrity. Base consumption is only 7.5 W, so the card generates limited heat inside a densely packed cabinet. Discrete machine states are read through digital inputs that recognize 24 V / 3 mA levels, matching standard sensor and PLC sources. All motion data are exchanged over the deterministic optical bus identified as SERCOS II, which provides synchronized cyclic updates for velocity, position, and diagnostic words. This interface set supports closed-loop control with standard industrial signal levels and synchronized network exchange.

Commanded feedback or test values can be retransmitted to downstream devices through an analog output rated at 5 V / 1 mA. Sourcing outputs can drive relay coils or indicator lamps at 24 V / 0.5 A. During power-up, the card draws an inrush of 4 A, a figure used when sizing fuses and backplane traces. Resolver or EnDat feedback from remote axes can be routed over the secondary channel with cable runs up to 75 m when sense lines are used, enabling decentralized installations while keeping signal quality within limits. Additional supplies for encoder excitation, such as 11.6 V ENS power at 500 mA, are internally monitored to support stable feedback operation and data consistency.
