Product Description:

The industrial control card CSH01.1C-SE-EN2-EN2-NNN-L2-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed in modular drive racks, the card generates axis commands, processes feedback, and connects higher-level PLCs through the SERCOS II fiber-optic bus. Its role in automation is to coordinate torque, speed, and position loops so that servo inverters follow precise motion profiles without external signal conditioning. This arrangement allows motion control, feedback processing, and network communication to remain concentrated in one control stage inside the drive system.

The analog interface accepts input signals up to ±10 V, and an input resistance of 160 kOhm minimizes loading on source devices such as pressure transducers. For actuator commands, the card can source a reference of 5 V at 1 mA, enabling direct connection to common drive enable lines. Digital sensing ports draw only 3 mA per channel at the expected field voltage of 24 V, which helps reduce demand on the control power supply. Output drivers support 0.5 A, which is suitable for relays or opto-isolated solenoids. Two encoder inputs accept EnDat 2.1, 1 Vpp, or 5 V TTL transducers, so the controller can close position loops with either absolute or incremental feedback. Safe Torque Off is integrated to cut motor energy without an additional safety relay, and the internal relay contact reports status to an interlock chain.

Start-up transients are limited to 4 A for a maximum duration of 100 ms, which helps cabinet fuses withstand power-up without nuisance trips. For setup or legacy serial links, the RS-232 service port transfers diagnostic data at up to 115 kBaud. This connection supports direct local access for status checks and parameter handling when a serial interface is preferred. Alongside SERCOS II real-time messaging, the mixed communication scheme lets the card support both optical network control and straightforward serial communication.
