Product Description:

The CSH01.1C-PB-EN1-NNN-NNN-NN-S-XP-FW is a single-axis control section produced by Bosch Rexroth Indramat for integration into the CSH Advanced Controllers series. Installed in modular IndraDrive power sections, it coordinates servo and spindle drives and exchanges real-time data with higher-level PLCs through its fieldbus channels. By executing motion sequences, monitoring feedback devices, and issuing drive commands, the card provides the deterministic control required for industrial automation lines, packaging machines, and material-handling systems.

Total controller demand remains low; the base board draws only 7.5 W from the shared 24 V DC bus, while the PROFIBUS communication board adds 2 W and the EN1 encoder interface consumes an additional 6 W. All cyclic machine data is exchanged over PROFIBUS, routed through a shielded trunk that terminates on the onboard 9-pin D-Sub female connector. Parameter adjustments are made with the supplied standard control panel, and the backing panel offers a 15-pin D-Sub female socket for the EN1 feedback wiring. No integrated safety technology is present, so safe-torque-off or emergency stop functions must be handled by external hardware.

For position verification, the card supports a combined resolver and HSF encoder interface. The excitation source supplies 8 V DC to the sensor, then superimposes a resolver carrier of 18.2 Vpp at 4 kHz. Returned sine and cosine channels are accepted as 1.0 V amplitude signals, and the high-speed feedback track may draw up to 250 mA. On the resolver side, the input stage tolerates a load of 35 ohms and permits 70 mA of supply current without saturation. These electrical limits ensure clean feedback signals during high-acceleration moves and allow the control loop to maintain precise velocity and position regulation.
