Product Description:

The CSH01.1C-ET-ENS-EN2-EN2-L2-S-NN-FW is a configurable motion and safety controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power section, it executes position loops, safety logic, and network gateway tasks so that multiple servo axes receive deterministic commands. Within automated packaging, assembly, and machining stations, the card functions as the supervisory layer that links PLC instructions to real-time motor currents while also monitoring feedback devices and safe-torque-off channels. Because control and feedback resources are concentrated on the plug-in board, cabinet space is saved and wiring is reduced compared with stand-alone controllers.

It draws a base load of 7.5 W during steady operation, yet the design allows a momentary inrush of 4 A when the DC bus is first charged. For encoder support, the primary channel supplies 12 V and a secondary channel offers 5 V, letting mixed absolute and incremental sensors share a single controller. Command and diagnostic data flow through the integrated Multi-Ethernet interface, so EtherNet/IP, PROFINET, EtherCAT, and SERCOS III are selectable in software. An auxiliary analog monitor outputs 5 V at 1 mA for scaled velocity or torque values, while the safe-torque-off function uses a 24 V, 3 mA control input that isolates external safety relays from the drive electronics.

Time-critical feedback recognition uses a maximum trigger width of 100 ms, enabling the card to capture short fault states without false retriggering. Ethernet can be bypassed and parameters can be accessed through the auxiliary RS232 port, which remains active even when the network stack is reset. The communications daughterboard adds only 2.2 W to the thermal budget, permitting dense multi-axis racks without additional cooling fans. When a safety sequence is confirmed, the controller delivers an acknowledgment on the STO terminal at DC 24 V / 1 A, providing enough current to drive redundant contactors while keeping isolation from the low-power logic domain.
