Product Description:

The CSH01.1C-PL-EN1-EN2-MEM-S1-S-NN-FW is a motion-logic control section produced by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. The unit serves as the computational core of modular servo inverters, processing encoder feedback, safety signals, and field commands to coordinate axis movement in industrial automation cells. By combining interface functions and encoder channels on one board, it helps simplify cabinet layouts while supporting synchronized drive operation across multiple axes. This arrangement also reduces the need for separate interface hardware inside the inverter assembly.

During normal operation, the section draws a base load of 7.5 W, which helps limit heat buildup inside the drive rack. Command data reaches the board through a Parallel Interface, so time-critical position words can be transferred simultaneously rather than serially. Encoder channel 1 processes resolver data through a converter with 12-bit resolution, giving sufficient detail for standard servo loops. The secondary encoder port supplies its electronics with 5 V logic power and presents an input impedance of 120 ohms, which helps preserve signal integrity on terminated cables. Channel 1 also energizes its sensor with an 8 V high-speed frame supply, and the resolver track uses an 18.2 Vpp carrier to maintain stable sinusoidal feedback during operation.

For faster electronic gearing, the same secondary port can accept square-wave feedback up to 1000 kHz, allowing high-speed incremental encoders to report motion without aliasing. Pulse-train capture for camming is limited to a maximum width of 100 ms, which prevents excessively long pulses from latching the position counter. Memory-module communication supports cable runs up to 40 m, making it possible to place remote control panels outside restricted machine areas. At power-up, the controller can draw an inrush surge of 4 A, which is important when sizing protective devices and arranging supply sequencing. These operating characteristics suit the board to modular drive systems that rely on accurate feedback handling and dependable signal exchange.
