Product Description:

The CSH01.1C-NN-EN2-NNN-MA1-S1-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. This controller is installed in drive systems where it coordinates feedback, analog references, and safe digital signals. That allows servo axes to follow commanded positions and speeds in industrial automation cells.

The controller is powered from a control circuit that must supply DC 24 V; this low-voltage input keeps the logic electronics isolated from main drive power. Four dedicated control-panel keys allow local parameter access without external tools. The EN2 interface digitizes incremental encoder feedback through a 12-bit A/D converter with a conversion resolution of 12 Bit. It also energizes the sensor with a regulated DC 5.0 V source while providing up to 350 mA of current for demanding encoders. Incoming differential tracks pass an anti-aliasing filter whose cutoff is 500 kHz, so high-speed position data are captured without distortion. The interface presents 120 Ω input impedance and drives 35 Ω line loads, which helps prevent signal reflections on long shielded cables.

The MA1 mezzanine handles process references. Two differential analog inputs and two analog outputs share 12-bit resolution, enabling machine controllers to exchange precise ±10 V signals without digital bus latency. Encoder-independent feedback counts are processed in hardware, while motion commands enter through the same analog channels. Machine safety circuits connect to a D-Sub 9-Pin (Female) header; each opto-isolated input draws 3 mA, and solid-state outputs can source up to 0.5 A. A form-C relay provides galvanic isolation for emergency chains and is rated for DC 1 A switching. Differential signaling on the analog side, shown by the Differential input type, helps maintain noise immunity inside enclosures crowded with high-frequency pulse trains.
