Product Description:

The CSH01.1C-SE-ENS-EN2-MD1-S2-S-NN-FW is a single-slot motion controller card from Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in Rexroth drive stacks, it operates as the local command processor for a servo axis, interpreting encoder signals and passing setpoints to the power stage. Within automated packaging lines, pick-and-place gantries, or material-handling stations, the card ties the drive train to the plant PLC through the deterministic SERCOS II network, providing synchronized position, velocity, and safety coordination.

It draws a baseline power of 7.5 W, a value used when calculating enclosure heat dissipation. During startup, the supply must tolerate an inrush of 4 A that can last up to 100 ms before settling to steady state. The module manages exactly 1 drive axis, which simplifies parameter handling and minimizes cross-channel latency. Expansion headers provide 12 digital input lines for sensors and 8 digital output lines for relays or solenoids, reducing the need for external I/O cards. Commands, status words, and diagnostic telegrams are transported over the SERCOS II optical ring, while the primary encoder channel is supplied with 12 V to maintain differential signal amplitude.

The analog interface can deliver a reference of 5 V at up to 1 mA, supporting speed trims or torque commands for auxiliary devices. For direct access, an RS-232 port supports cable lengths up to 15 m and communicates at rates up to 115 kBaud. Safe Motion functionality is enabled through a monitored 24 V, 3 mA input and an internal relay rated at DC 24 V / 1 A, allowing certified stop channels without cutting the main link. A secondary encoder feed is powered from an isolated rail, which helps separate feedback power from the main control interface.
