Product Description:

The CSH01.1C-SE-EN1-NNN-MD2-L1-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a plug-in module that forms the command layer inside IndraDrive servo inverters, handling axis coordination, feedback processing, and fieldbus exchange. By managing analog signals, discrete I/O, and serial links on one board, the unit supports precise positioning, speed control, and machine-sequencing tasks typically found in packaging, printing, and material-handling equipment.

Two differential analog channels accept input swings up to ±10 V, and a front-end impedance of 160 kΩ prevents loading of external sensors. A single output channel supplies control voltages from 0 to +5 V for drive-internal diagnostics or external followers. Motion commands and status data move over the real-time fiber link SERCOS II; the module supports a transfer rate of 16 MBaud, so cycle times stay within servo bandwidth demands. The MD2 extension on this version adds sixteen digital inputs and sixteen digital outputs that can be mapped to PLC variables for fast interlock processing. An L1 acknowledge line provides 24 V at 1 A to energize external relays, while the separate L1 control signal draws only 24 V at 3 mA, isolating logic triggers from power switching.

Resolver feedback is energized with 18.2 Vpp at a carrier of 4 kHz, enabling the built-in resolver and HSF evaluation circuit to derive absolute rotor angle without incremental homing. For linear encoders, the MD2 SSI port executes absolute position detection and streams the value directly into the motion kernel. An asynchronous maintenance interface runs at 115 kBaud on the RS-232 connector for parameter backup or service commands. When integrated into safety chains, the controller actuates the Starting Lockout function, ensuring that drive-enable signals are blocked until a confirmed reset is issued.
