Product Description:

The CSH01.1C-SE-EN2-NNN-NNN-S2-S-XP-FW is a motion-control processor board manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in Rexroth drive racks, it supervises axis interpolation, issues setpoints to power modules, and executes integrated safety tasks for industrial robots, packaging lines, and conveyor systems. This arrangement allows the control platform to coordinate motion commands, feedback handling, and protective functions within the same drive assembly.

The board exchanges real-time data through a SERCOS II fiber link that reaches 16 MBaud, allowing synchronized position updates among multiple drives. Two analog monitor channels source up to 1 mA at a programmable level of 5 V, so external oscilloscopes or PLC analog cards can track internal variables without additional buffering. Digital sensor blocks receive field power from the controller, and the available supply peaks at 1.1 A, which is sufficient for typical limit switches and light curtains. During cabinet energization, the card draws an inrush current of 4 A for 100 ms and then settles to a continuous power demand of 7.5 W. A relay output on the front edge is rated at DC 24 V / 1 A and can switch motor contactors or hydraulic valves directly.

Position feedback is accepted through the EnDat 2.1 protocol, and the interface delivers up to 350 mA into encoders with a maximum load of 35 ohms. Logic processing follows 5 V TTL rules, while the sense lines regulate a dedicated 5.0 V supply to minimize cable-drop errors. Sinusoidal encoder tracks are decoded through a 1 Vpp signal pair for high-resolution measurement on linear or rotary axes, and a brief surge current of 4 A is tolerated by the feedback receiver during power-up without loss of position. All motion-related outputs are supervised by the controller’s Safe Motion function, which imposes speed limits and torque shutdowns when guard doors open or emergency-stop chains activate.
