Product Description:

The CSH01.1C-ET-ENS-NNN-NNN-S2-S-XP-FW is an axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, the card interprets high-level machine commands and generates time-critical setpoints for attached servo inverters, providing deterministic motion sequencing in packaging lines, printing presses, and material-handling cells. Its embedded ET communication layer handles Ethernet messaging, while the ENS circuitry processes feedback from incremental or absolute encoders, allowing the drive to close velocity and position loops internally without external PLC resources. Because command processing and feedback evaluation are handled in the same control section, the drive can react quickly to changing axis conditions during repeated motion cycles.

The analog interface can source up to 1 mA, and each increment on that channel corresponds to 19.5 mV/inc; this combination permits fine voltage reference generation for speed or torque commands. When operated as a voltage source, the channel is limited to 5 V, matching the input range of many legacy drive cards. Core electronics draw only 7.5 W, which helps reduce heat inside the drive assembly. Discrete field devices such as relays can be driven directly because each digital output supplies 500 mA, while the sum of all digital outputs must stay below 1000 mA to avoid overstressing the onboard transistors. That output capacity supports direct switching of small machine signals where separate interface hardware is not required.

Encoder circuits are supplied with 12 V from an isolated regulator, eliminating the need for an external sensor power rail. The ET module exchanges data over standard 100Base-TX Ethernet through an 8-pin RJ-45 connector and maintains link integrity along cables up to 100 m. Soft-start circuitry caps initial demand at 4 A, which helps the controller share power buses with adjacent axes without tripping line protection. The ENS section adds 6 W of load and the ET section adds 2.2 W, while timing outputs can generate pulses as short as 100 ms through the Safe Motion D-Sub, 9-pin interface. The short pulse capability is useful where the drive must exchange brief timing signals with safety-related or synchronized machine functions.
