Product Description:

The CSH01.1C-PB-EN1-EN2-NNN-L2-S-NN-FW is a single-axis motion and logic controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It coordinates one servo axis through integrated drive control, I/O handling, and fieldbus exchange to streamline automated machine cells, packaging systems, and assembly lines in general industrial automation. Because motion control and logic functions are combined in one unit, it fits compact machine layouts where centralized control and deterministic axis behavior are both required. Safe Torque Off circuitry disconnects drive power through hardware logic, and the single-axis design maintains deterministic timing by dedicating all resources to one motion channel.

Its base electronics draw only 7.5 W from the control cabinet supply, so thermal loading is minimal. Communication with higher-level PLCs is handled through PROFIBUS, and telegrams enter the unit through a D-Sub 9-pin female connector. This arrangement supports cyclic data exchange with the supervisory control system while keeping cabinet wiring straightforward. The primary feedback port supports resolver signals in Resolver/HSF format modulated at 4 kHz and energized with 18.2 Vpp, giving precise rotor angle data even at low speed. A second interface, compatible with EnDat 2.1, 1 Vpp, or 5 V TTL protocols, powers digital or incremental encoders and can source up to 350 mA to the sensor, permitting long cable runs without voltage collapse. The combination of resolver and digital encoder support allows the controller to work with different motor feedback types used in industrial servo systems.

Startup demands are controlled by an inrush limiter that caps line surge at 4 A, and output pulses to external devices can be stretched to 100 ms through the built-in relay rated at 24 VDC and 1 A. The secondary encoder supply delivers 5.0 V regulated for connected feedback devices. The front-panel RS-232 maintenance port spans 15 m at rates up to 115 kBaud for parameter upload and diagnostics. This service connection allows local access for configuration and troubleshooting without interfering with the main motion interfaces.
