Product Description:
The CSH01.1C-SE-EN1-EN2-MEM-L1-S-NN-FW is a single-axis motion controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on the front of an IndraDrive power section, it handles setpoint generation, feedback evaluation, and network communication for industrial automation cells. Mechanical dimensions of 241 mm in height, 49.5 mm in width, and 103 mm in depth allow dense multi-axis mounting inside a control cabinet while maintaining side-by-side airflow. Its primary fieldbus is the SERCOS optical interface, so the unit synchronizes drives, PLCs, and high-resolution encoders within a deterministic communication cycle.
The controller’s two differential analog inputs present an impedance of 160 kΩ, minimizing load on external transducers while accepting command signals across a ±10 V range. Four sourcing digital outputs supply up to 0.5 A per channel at a nominal 24 V, enabling direct actuation of contactors, brake relays, or status lamps without auxiliary relays. Encoder interface 1 supports HSF / RSF formats, allowing connection of high-speed sine-cosine encoders for precise phase evaluation. A dedicated 5 V sensor rail powers these encoders, and a 24 V probe input is provided for position-latch functions. This arrangement lets the controller accept command signals while switching external devices from its onboard outputs.
Interface 2 accepts absolute feedback via EnDat 2.1 / 1Vpp / TTL, so it can read multiturn positions or incremental tracks from a broad encoder portfolio without daughterboards. Internally, the MEM option generates step-direction or SSI data at a maximum frequency of 1 MHz, and its delay line is limited to 650 ns; this timing supports deterministic emulation of legacy feedback for retrofit drives. The safety layer enforces a Starting Lockout that prevents unintended motion until the enable chain is closed. This combination allows the controller to work with both modern absolute encoders and legacy feedback schemes in retrofit applications.
