Product Description:

The CSH01.3C-S3-EN2-EN2-CCD-NN-S-NN-FW is a compact control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into an IndraDrive power unit and supplies the real-time processing needed for multi-axis motion. By coordinating network traffic, local I/O, and encoder feedback, the board streamlines drive integration inside automated machinery where consistent position loops and synchronized axes are essential for throughput and repeatability. In high-speed industrial automation cells, it converts SERCOS III telegrams into analog, digital, and relay-level commands. Because the control section is separate from the power stage, motion processing and signal handling can be managed within the controller while the power unit delivers motor current.

This controller offers an analog input bandwidth of 1.4 kHz, allowing fast capture of process signals, while its input resistance of 160 kΩ minimizes loading on upstream transducers. Each input is digitized in steps of 1.23 mV/inc, and the corresponding analog outputs resolve to 19.5 mV/inc with a full-scale drive level of 5 V for external actuators. Two EN2 encoder ports furnish differential feedback channels and a regulated 5 V supply, which supports synchronized position sampling from connected devices. Motion data and parameter sets are exchanged over the SERCOS III control bus, and the board can also serve as the master for cross-communication on the same medium. This arrangement supports tightly coordinated axis behavior when multiple drives must exchange timing and position information during operation.

Base consumption of 8.5 W keeps cabinet heat gain low, yet the unit can switch pulse patterns up to 16 kHz, matching high-frequency current loops in compact motors. The digital outputs source up to 500 mA, and the relay channel is rated for 24 V DC at 1 A for peripheral contactors. On power-up, an inrush draw of 4 A lasts only 100 ms, limiting fuse stress, while a dedicated inrush limiter protects the circuitry during repeated starts. These output and startup characteristics support stable interaction with connected devices without placing unnecessary load on the surrounding control hardware.
