Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-S2-S-XP-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on an IndraDrive rack, it houses the signal processor and fieldbus ports that supervise a single axis and share timing with neighboring sections over fiber-optic SERCOS. It converts incremental or absolute encoder data into position values and forwards reference commands to the linked power inverter. In presses, gantries, and pick-and-place stations, the unit keeps position, velocity, and torque trajectories within defined tolerances while applying drive-integrated Safe Motion functions.

The controller accepts symmetrical command voltages up to ±10 V on its differential analog input. That channel has an input impedance of 160 kΩ, and each step is quantized at 1.23 mV/inc. An analog output resolves changes in 19.5 mV increments for real-time status feedback. Network traffic is carried on a fiber ring at 16 MBaud, and a service RS-232 port operates at 115 kBaud for setup and diagnostics. Integrated Safe Motion blocks execute STO, SS1, and SLS functions locally. Power-up draws an inrush of 4 A for 100 ms before settling to logic demand. The sensor connector provides a regulated 11.6 V rail for external encoders, while a 120 Ω termination maintains signal fidelity for differential lines that use the SSI absolute format.

During emulation mode, the section can generate virtual encoder signals at 1 MHz to synchronize axes that lack physical feedback. These signals remain stable over a permitted cable run of 40 m, allowing remote drives or controllers to reference the same position clock without degradation. The internal encoder supply can source 500 mA, so several sensors or active splitters may be powered directly from the board. Base electronics draw only 7.5 W, enabling passive cooling when the card is mounted in densely packed cabinets.
