Product Description:
The CSH01.1C-PB-EN1-EN2-NNN-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive stacks, it serves as the command layer that links higher-level PLCs with Indramat servo inverters, executes motion profiles, and supervises Safe Motion functions. The unit integrates signal conditioning, fieldbus communication, and encoder evaluation so that servo motors in packaging, handling, and printing lines follow precise speed and position commands from the automation network. This arrangement keeps control, feedback handling, and network exchange in one section of the drive system.
One analog channel offers an input impedance of 160 kΩ, so connected transducer circuits are not heavily loaded, and the same channel accepts a symmetrical reference range of ±10 V for speed or torque commands. The controller returns process feedback on a dedicated analog output rated at 5 V, 1 mA. Discrete signaling uses digital inputs rated at 24 V, 3 mA; eight of these points can capture sensor states or trigger interrupts with pulse widths as short as 100 ms. All real-time commands and diagnostics travel over the integrated PROFIBUS interface, allowing deterministic data exchange with Rexroth or third-party PLC platforms. Digital outputs source 24 V at 0.5 A for actuator coils or status lamps.
During power-up, the section draws a peak of 4 A; afterward, its typical consumption settles at 7.5 W, which helps simplify cabinet thermal planning. Motion supervision follows the Safe Motion concept, and the controller verifies that an encoder is connected. Channel two supports EnDat 2.1 as well as 1 Vpp or 5 V TTL formats, while channel one matches MHD and MKD motor encoders. Nonvolatile parameters and update files are loaded through the front-mounted MultiMediaCard slot. Additional service access is available through the RS232 serial port, and a relay output rated at 24 V DC and 1 A provides a drive-ready indication to the main control circuit.
