Product Description:

The CSH01.1C-SE-ENS-EN2-NNN-L2-S-XP-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for slotting into IndraDrive modular inverters, it supplies motion command processing, encoder handling, and Safe Torque Off logic for automated packaging lines, material-handling cells, and other factory equipment. By concentrating communication, feedback, and safety functions on one board, it simplifies cabinet layouts and reduces wiring in multi-axis machines. It also centralizes feedback and safety interfaces so the drive can be integrated without separate add-on boards for common axis tasks, which helps keep the drive assembly compact.

Its fieldbus port uses SERCOS II to exchange cyclic setpoints and diagnostics with higher-level PLCs. The analog monitoring channel presents an input resistance of 160 kΩ, preventing measurable loading of connected sensors. Command voltages leave the board with a resolution of 19.5 mV/inc, enabling accurate torque and speed modulation. During idle operation, the electronics draw only 7.5 W, easing thermal management inside compact cabinets. Each digital output can source up to 500 mA, so relays or pilot valves may be driven directly. The secondary encoder socket accepts EnDat 2.1, 1 Vpp, or 5 V TTL feedback, giving flexibility when retrofitting mixed transducer types across existing machine platforms.

The auxiliary supply rails power connected sensors: the EN2 channel provides 350 mA at 5.0 V for a second encoder, while the ENS rail furnishes 11.6 V at 500 mA for SinCos devices. Hardware Safe Torque Off is implemented; its acknowledge output is rated at 24 V / 1 A and the control input accepts 24 V at 3 mA with a maximum pulse width of 100 ms, enabling safety PLCs to remove drive torque within one control cycle. Typical inrush current peaks at 4 A, so supply fuses and traces must tolerate the short surge. An RS-232 service port supports cable runs up to 15 m, allowing parameter access without network interruption.
