Product Description:

The CSH01.1C-SE-EN1-EN2-M01-S1-S-NN-FW is a plug-in motion and safety controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in Rexroth drive racks, this board orchestrates axis commands, processes encoder feedback, and manages safe torque-off channels so that connected servo drives follow deterministic motion profiles inside automated machinery. By combining real-time fieldbus communication with integrated analog and relay interfaces, the module serves as the central logic element between higher-level PLCs and individual power inverters, ensuring coordinated speed, position, and safety interlocks in packaging lines, transfer systems, and material handling stations.

During operation, the controller’s electronics draw a base power of 7.5 W, while the optional EN1 communication slice adds another 6 W to the internal load budget. Line insertion produces a typical inrush of 4 A followed by a limited 100 ms pulse window so cabinet fusing can be sized accurately. Real-time motion data moves over the fiber-optic SERCOS 2 ring, enabling synchronous updates for all axes. Two analog monitor channels are provided; each can source up to 1 mA or supply a reference of 5 V for drive diagnostics or external indicators. At power-up, the safety logic receives 24 V through inputs limited to 3 mA and can assert dual redundant outputs rated at 24 V / 0.5 A to trip contactors when a fault is detected.

Feedback handling is completed by two encoder ports. The first channel accepts resolver or HSF signals, whereas the second port supports EnDat 2.1, 1 Vpp, or 5 V TTL formats and can drive up to 350 mA at 5 V to power the sensor head. When cabling without sense conductors, the En2 output remains stable over runs up to 50 m; with sense wires, the limit extends to 75 m, allowing large gantry layouts without excessive voltage drop. The board also carries a form-C relay whose contacts are rated at DC 24 V / 1 A for field feedback or ready signals to a supervising PLC.
