Product Description:

The CSH01.1C-CO-EN1-NNN-MD2-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat and is part of the CSH Advanced Controllers series. Installed in an IndraDrive power stack, the board governs servo or spindle axes, exchanges data with higher-level PLCs, and supervises encoder signals to keep motion profiles synchronized with process demands. By combining fieldbus interfacing, drive logic, and sensor supply on one card, it streamlines cabinet layouts and simplifies setup in automated assembly lines, packaging stations, and material-handling equipment.

The analog interface presents an impedance of 160 kΩ, so standard industrial signal sources can be connected without noticeable loading. Base electronics draw only 7.5 W, minimizing thermal rise inside the drive. For networked control, the communication module supports DeviceNet / CANopen, giving deterministic exchange of setpoints and diagnostics. Sixteen programmable inputs accept limit switches through a threshold of 24 V / 3 mA, while matching transistor outputs can source up to 24 V / 0.5 A to drive contactors, indicator lamps, or interlock relays. These electrical limits support safe external wiring and help determine appropriate overcurrent protection.

The MD2 option extends discrete handling with 16 additional inputs and 16 outputs that can be scanned or refreshed through the internal backplane without occupying fieldbus bandwidth. Sensor feedback is processed by a resolver or HSF channel; the HSF converter resolves positions to 12 bit and can deliver up to 250 mA at 8 V for encoder excitation. For resolver feedback, a carrier of 4 kHz is driven at 18.2 Vpp so that small signal amplitudes remain resistant to cable noise. When an SSI absolute encoder is used, the board supplies 0.2 A to the transducer, allowing long cable runs while maintaining logic-level integrity.
