Product Description:

The CSH01.1C-PB-ENS-EN2-MEM-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It installs in IndraDrive drive stacks and manages motor position, velocity, and torque loops for automated machinery. By combining fieldbus communication, encoder evaluation, and integrated safety, the module coordinates precise motion while minimizing external wiring in multi-axis production cells. The unit acts as the intelligence layer between higher-level PLCs and power modules, translating network commands into real-time drive signals used in packaging, printing, and material-handling applications.

It evaluates a secondary feedback device through an additional encoder interface that accepts EnDat2.1/1 Vpp/5 V TTL protocols. This channel is energized from a dedicated supply of 5 V to isolate it from the main motor feedback circuit. When remote sense leads are used, encoder cabling can reach 75 m, allowing controller cabinets to be located away from moving axes without signal degradation. Motion and diagnostic data exchange with the host PLC occurs over PROFIBUS-DP through the X30 socket, which uses a D-Sub 9-pin female connector. The primary motor encoder port supports IndraDyn/HIPERFACE®/1 Vpp, giving sinusoidal or serial feedback for high-resolution commutation.

The safety subsystem meets Category 3 requirements through the drive-integrated Safe Motion function. This feature operates alongside a motor encoder supply of 12 V to maintain continuous monitoring of speed and position. Drive shutdown commands exit the module on outputs rated at 24 V / 0.5 A, while a redundant contact set provides DC 24 V / 1 A switching for power stage isolation. Parameter access is handled through the RS232 service interface, enabling local setup without occupying the fieldbus. Galvanic isolation of emulated absolute and incremental signals prevents ground loops when the controller shares reference lines with distant automation equipment.
