Product Description:

The CSH01.1C-SE-EN1-EN2-MEM-NN-S-NN-FW is a single-axis controller module from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It plugs into an IndraDrive power section and supervises torque, velocity, or position loops for servo motors used in material handling, packaging, and general motion cells. By combining primary and secondary encoder channels with flexible I/O, the unit coordinates real-time drive commands and exchanges status data with higher-level PLCs over the SERCOS interface. This arrangement lets one controller manage motor feedback and external device signals within the same axis.

The analog reference channel delivers an output level of 5 V, allowing the module to feed speed or torque setpoints to legacy drives that still rely on voltage control. For closed-loop current regulation, the internal computation refreshes every 125 µs, which lets the drive react quickly to load fluctuations. Discrete actuators such as contactors can be driven directly because each digital output can source up to 500 mA. Base dissipation stays at only 7.5 W, so cabinet thermal loading is minimal, yet the supply must be sized for a startup draw of 4 A to charge internal capacitors. The combination of analog signaling, fast processing, and onboard outputs supports stable control during normal machine operation.

Communication with the motion network occurs over SERCOS II, with a minimum loop time of 1000 µs, while single-shot commands may be stretched to a maximum pulse width of 100 ms for tolerance to slower peripherals. The MEM interface supports encoder-derived position capture at up to 1 MHz and permits cable runs as long as 40 m without repeaters. Form-C relay contacts on the board can switch auxiliary loads rated at 24 V DC / 1 A. Primary feedback is accepted from a resolver or HSF sensor, and the resolver excitation line is fixed at 8 V. Secondary feedback inputs accommodate EnDat 2.1, 1 Vpp, or 5 V TTL formats, while encoder emulation can output both absolute and incremental codes for downstream devices. This range of feedback options allows the controller to support different encoder technologies on the same platform.
