Product Description:

The CSH01.1C-ET-EN2-EN2-MA1-L2-S-NN-FW is a controller card from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It plugs into IndraDrive power sections and executes motion sequences, trajectory calculations, and safety monitoring for multi-axis machinery. By combining drive control with fieldbus switching and encoder evaluation on one plug-in module, it streamlines cabinet wiring and shortens control loop times in automated production cells. It is suited for machines that require coordinated axis motion, fast response to command changes, and stable feedback processing during continuous operation.

When powered from the 24 V cabinet rail, the module draws only 7.5 W, easing demands on auxiliary supplies. The base analog input channel presents a high impedance of 160 kΩ to minimize sensor loading, while each analog output can source up to 1 mA for actuators tied to a 5 kΩ load. Digital-to-analog conversion occurs in increments of 19.5 mV/inc across the ±10 V range, which supports fine command adjustment. System communication is handled through a Multi-Ethernet backplane that can be configured for EtherNet/IP, EtherCAT, SERCOS III, or PROFINET without hardware changes. For the secondary encoder supply, the En2 regulator provides a stabilized 5.0 V rail to incremental or EnDat transducers.

The second encoder channel accepts 35 Ω termination and can deliver up to 350 mA, supporting high-resolution feedback devices that require significant excitation current. A service port operates at 115 kBaud for RS-232 diagnostics, enabling parameter uploads during setup without disrupting real-time traffic on the Ethernet network. Functional safety is built in through the certified Safe Torque Off feature, which disconnects gate signals to the power stage to remove motor torque during emergency stops. Two differential analog inputs and two analog outputs supplied by the MA1 extension complete the signal set for process variables, while dual EnDat 2.1 interfaces maintain precise position reporting for closed-loop motion tasks.
