Product Description:

The CSH01.1C-SE-EN2-MA1-MD1-S1-S-NN-FW is an axis controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive control section, it coordinates multi-axis motion in machine tools, packaging lines, and material-handling systems. The card converts SERCOS network commands into drive-level setpoints and safety signals while maintaining deterministic communication between the PLC, feedback devices, and power stages. Integrated analog and digital channels also allow direct connection of sensors, actuators, and light curtains without separate I/O racks, which helps reduce panel space and wiring.

The board includes two analog input channels that accept command voltages in the ±10 V range for torque or velocity references from process controllers. It also provides two analog output channels across the same ±10 V range for monitoring or for passing reference values to other equipment. Each analog path uses 12-bit resolution, which provides 4,096 discrete levels while keeping conversion latency low. For discrete control, 12 digital input channels receive signals from items such as limit switches, and 8 digital output channels can operate contactors or pilot lamps. All cyclic setpoint, status, and parameter data are exchanged through the SERCOS interface on fiber optic cables.

The controller has a configured power draw of 19.5 W, and its power terminals can experience an inrush current of 4 A when the rack is energized. Position feedback is handled through the EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface, which allows mixed encoder types on the same axis. For safety functions, the card supplies 3 mA on each light-barrier input and can sink 0.5 A across the solid-state safety outputs. When a fault is detected, it actuates an internal relay rated at 24 V DC, 1 A with a maximum pulse width of 100 ms to remove torque-enable commands.
