Product Description:

The CSH01.1C-ET-EN1-NNN-MEM-S2-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on an IndraDrive modular inverter, it supervises motion axes, processes field feedback, and triggers safe states in automation cells where deterministic speed, position, and torque loops are required. Its task is to translate network commands into drive-level signals while continuously monitoring sensor channels and internal diagnostics.

The analog command channel accepts reference signals inside a ±10 V window, and a 160 kΩ input impedance minimizes loading on upstream PLC outputs. For position feedback to external devices, the board supplies a 5 V, 1 mA analog output, and each digital power stage can source 24 V, 0.5 A for direct actuation of contactors or indicators. Motion and safety data flow through the Multi-Ethernet master port, which supports SERCOS III, EtherNet/IP, and PROFINET without hardware changes. The control section includes the certified Safe Motion (S2) function, allowing limited-speed or safe-stop modes without separate relays. Encoder emulation is installed, the native HSF/RSF interface accepts HIPERFACE or resolver transducers, a relay rated at 24 VDC and 1 A is present for fault annunciation, the RS232 service port supports setup and service tasks, and the pulse generator output maintains a 100 ms width for time-stamped events.

During startup the section draws an inrush of 4 A, a figure that must be considered when sizing cabinet fuses. Edge-triggered probe inputs react within 1 µs, giving the controller the precision needed for print-mark registration or high-speed cutting. The housing occupies only 49.5 mm of rack width, rises to 241 mm in height, and measures 103 mm deep, so multiple sections can be stacked in compact enclosures while still meeting airflow requirements.
