Product Description:
The CSH01.1C-SE-EN2-EN2-NNN-S2-S-NN-FW is a plug-in control module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power section, it acts as the motion and I/O processor that links servo drives to higher-level PLCs and field networks in automated machinery. Through parameter settings, it coordinates axis dynamics, manages encoder feedback, and supervises safety functions required for industrial automation cells.
The module exchanges cyclic setpoints and diagnostics over a SERCOS II fiber-optic ring, and its bus hardware supports data telegrams up to 16 MBaud. Two differential analog inputs accept command voltages within a span of ±10 V, and each input presents an impedance of 160 kΩ, so upstream signal sources are only lightly loaded. Internal electronics draw just 7.5 W during steady operation, yet DC-link charging can produce an inrush current of 4 A, so cabinet fusing must tolerate that short surge. Four configurable digital points can be set as inputs or outputs, and fixed digital channels accept 24 V at 3 mA or switch 24 V at 0.5 A, enabling direct connection to light curtains, proximity sensors, and contactors.
Auxiliary 24 V for field devices is limited to 1.1 A to protect board traces during short circuits. Motion integrity is enhanced by the integrated Safe Motion functions that monitor velocity and position independently of the main CPU. Two identical encoder ports support EnDat 2.1, 1 Vpp, or 5 V TTL signals and deliver 5.0 V at 350 mA for each sensor. Where isolated outputs are necessary for contactor coils, a form-C relay is provided with a rating of DC 24 V, 1 A. The allowable inrush pulse lasts up to 100 ms, matching the ride-through of most switch-mode supplies, and the base I/O cluster is expandable through SERCOS to synchronize additional drives with millisecond accuracy.
