Product Description:

The CSH01.1C-PB-ENS-EN2-MA1-NN-S-NN-FW is a motion-control card from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It functions as the central control section inside an IndraDrive modular drive, coordinating servo loops, fieldbus traffic, and local analog or encoder feedback so a single mechanical axis can be driven with deterministic timing. By combining fieldbus master capability with onboard signal conditioning, the unit simplifies cabinet wiring and local signal integration in automated machinery. Within the drive assembly, it links network commands with local feedback processing and analog signal exchange from one control stage.

The controller supports a single-axis topology, concentrating all processing resources on one drive channel to reduce jitter during interpolation. Two analog input ports with two differential ±10 V, 12-bit analog inputs allow process variables such as torque demand or line pressure to be sampled directly, while two output ports with two-channel ±10 V, 12-bit analog outputs send commanded values to external actuators or regulators. Real-time communication with a higher-level PLC is handled through PROFIBUS-DP, and data rates up to 12 MBaud support fast update cycles in packaging, printing, or pick-and-place systems. The fieldbus interface uses a D-Sub 9-pin female connector, and a separate RS232 maintenance port provides local parameter access. This arrangement allows measured signals and reference values to move between the drive and external devices without separate interface modules.

A compact housing of 241 x 103 x 49.5 mm conserves panel depth. Convection slots keep typical heat dissipation limited to 7.5 W under full load, which helps the control section fit dense cabinet layouts. During power-up, the supply draws a 4 A inrush current for no more than 100 ms, keeping breaker sizing moderate. Motor feedback is handled through the first encoder socket, which accepts IndraDyn/HIPERFACE/1 Vpp signals to provide fine-resolution position data without extra converter boards. The compact enclosure also suits installations where drive components are mounted in shallow panels or closely spaced rows.
