Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-L1-S-K1-FW is a single-axis drive controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, this logic module handles motion coordination, feedback processing, and fieldbus communication for servo axes used in packaging machines, printing presses, and material-handling stations. By combining real-time bus access with integrated encoder interfaces, the device serves as the control core that converts program instructions into precise motor current commands and position data.

Command exchanges with higher-level PLCs occur over the SERCOS II control bus, a deterministic fiber-optic ring that delivers synchronized position updates within a 62.5 µs cycle. For analog feedback or process signals, the card supplies an output channel rated at 1 mA, and its digital outputs can switch loads up to 500 mA for valves or indicator lamps. The integrated digital-to-analog converter resolves setpoint voltages at 19.5 mV per increment, allowing fine scaling of speed or torque references without external trim circuitry.

The backplane interface relies on fiber-optic cables to maintain galvanic isolation between power and logic domains, and absolute shaft positions are decoded through the SSI format as well as incremental emulation for legacy devices. Internal sensor electronics receive a stabilized 12 V supply that supports IndraDyn, HIPERFACE, and 1 Vpp encoders during operation. An electromechanical relay rated at DC 30 V / 1 A is available for status signaling, while the module includes a hardware-implemented Starting Lockout input wired through a 9-pin D-Sub connector. It can also issue acknowledge signals at 24 V, monitor lockout contacts at 3 mA, and forward serial diagnostics through the RS232 port.
