Product Description:

The CSH01.1C-SE-EN2-NNN-MEM-S2-S-NN-FW is a drive controller section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside IndraDrive power modules, it coordinates servo axes and integrated safety functions in automated machinery. The unit converts incoming control commands into precise current, velocity, and position references for connected motors, allowing accurate motion on synchronized machine sections. Its compact controller format makes it suitable for installations where motion control, feedback handling, and machine-level coordination must be combined within the power module.

Motion commands reach the controller over SERCOS II at a deterministic throughput of 16 MBaud, supporting fast cyclic communication with the higher-level control system. The internal current loop updates every 125 µs, which helps maintain stable torque regulation during rapid changes in load and speed. Feedback is accepted through an encoder input that supports EnDat 2.1 / 1 Vpp / 5 V TTL, and the controller can output absolute or incremental emulated signals for secondary devices. Two analog outputs provide ±10 V reference or diagnostic signals, and one normally open relay contact indicates drive-ready status. A memory-based generator can stream setpoints up to 1 MHz, allowing smooth interpolation during high-resolution positioning tasks, while the safety input uses 24 V at 3 mA for connection to standard emergency-stop chains and light curtains.

Parameterization and trace capture are handled through the engineering port with 100Base-TX Ethernet, which supports direct access to diagnostics and setup data. The integrated Safe Motion package monitors speed, standstill, and direction without requiring external relays for those functions. Legacy service access remains available through RS232 signaling, which is useful when a simple local serial connection is preferred. During power-up, the module draws a typical inrush current of 4 A, so upstream protective devices must tolerate that brief surge without nuisance tripping.
