Product Description:

The CSH01.1C-PB-ENS-NNN-MEM-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The board attaches to an IndraDrive power module and supplies trajectory generation, fieldbus communication, and safety supervision for one servo axis in automated machinery. It also manages drive-side logic needed for coordinated motion, status handling, and signal exchange with the higher-level controller. By converting application commands into real-time PWM and encoder tasks, it creates the closed-loop interface between the plant's programmable logic controller and the drive stage.

The card handles analog reference and diagnostic signals through dedicated low-level interfaces. Its differential analog input tolerates up to ±10 V, allowing direct connection to PLC reference channels without external scaling. A high input impedance of 160 kΩ minimizes circuit loading so the upstream controller remains stable and the reference signal is not significantly disturbed. For diagnostic feedback, the card offers an analog output that spans 0–5 V and is specified for loads down to 5 kΩ, allowing standard data acquisition hardware to read actual position or torque. Internal electronics draw only 7.5 W of basic circuit power, so heat dissipation inside a tight cabinet remains limited and auxiliary 24 V supplies are lightly loaded.

System integration centers on the fieldbus port that speaks PROFIBUS-DP at configurable baud rates, giving deterministic command exchange alongside cyclic encoder data handled by the ENS evaluation module. The D-Sub 15-pin female connector carries the encoder signals, while the MEM emulation channel can stream reference pulses up to 1 MHz for legacy drives and retrofit installations. During power-up, the controller draws an inrush of 4 A, so fusing and supply wiring must account for that transient. When optional safety functions are activated, rated SIL functions are executed on the board's hardware layer. The embedded safety stack is identified here as Safe Motion, enabling controlled stop and monitored speed without additional relays.
