Product Description:

Bosch Rexroth Indramat’s CSH01.1C-S3-ENS-EN2-NNN-NN-S-NN-FW is a plug-in control section in the CSH Advanced Controllers series. It provides the computational core that supervises drive functions inside IndraDrive platforms. Within the drive, it handles command interpretation, feedback processing, and the control calculations needed for coordinated axis motion. It converts fieldbus commands into precise current and voltage references so that connected servo axes meet position and velocity targets on assembly lines, packaging equipment, and material-handling stations.

The controller’s internal logic draws only 7.5 W, minimizing heat inside compact cabinets. Two differential analog inputs span ±10 V and present an input resistance of 160 kΩ. This high impedance reduces sensor loading and helps preserve signal fidelity at the reference source. When the drive must pass a low-level reference to external devices, the onboard DAC sources a 0 to 5 V signal at up to 1 mA. A dedicated 1.1 A rail powers local I/O blocks, while an En2 encoder channel can sustain 350 mA from its regulated 5.0 V source for digital or 1 Vpp feedback. Separate Ens wiring supports resolvers or high-power encoders with 11.6 V at 500 mA so that devices with higher illumination or excitation demand remain within tolerance. Input conversion limits are maintained by an inrush-shaping network that confines the charging surge to 100 ms.

For real-time motion coordination, the module exchanges cyclic data over SERCOS III. A service port reaches up to 115 kBaud on RS-232 for local setup and diagnostics. Position transducers connect through EnDat 2.1, 1 Vpp, or 5 V TTL modes without auxiliary interface cards. This allows common feedback formats to be connected directly to the control section. External sensors and actuators receive their logic supply from the controller’s isolated bus, which accepts 19–30 V DC. At startup, the unit tolerates an inrush of 4 A, so the DC link capacitors can charge without nuisance tripping.
