Product Description:
The CSH01.2C-NN-EN1-MEM-CCD-NN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, the card supplies axis management, signal conditioning, and network interfacing for industrial automation equipment such as packaging machines, gantries, and converting lines. It acts as the primary logic element inside the drive, interpreting feedback devices, issuing torque commands, and linking the drive to higher-level Sercos and safety networks.
The unit accepts an analog command span of ±10 V and monitors that channel through an input resistance of 160 kOhm, which helps prevent excessive loading of upstream PLC outputs. For machine signaling, it provides a digital sourcing output rated at 24 V / 0.5 A, suitable for driving valves or contactors. The section can serve as the Cross Communication master through Sercos III, while the dedicated encoder feedback socket supports EN1 high-speed feedback or a resolver. Emulated encoder signals are available in incremental or SSI format for legacy motion controllers. An internal supply of 8 V DC feeds HSF sensors with up to 250 mA, eliminating the need for a separate external supply. The module does not include a master fieldbus interface, so network traffic remains concentrated on the Sercos ring.
The module has a height of 241 mm, a width of 49.5 mm, and a depth of 103 mm, which allows dense stacking inside a 300 mm cabinet depth. Resolver transducers receive 18.2 Vpp excitation, and the integrated relay contact can switch 24 V / 1 A loads for ready or fault indication. Feedback cabling for HSF devices may run up to the specified 40 m length without repeaters. Functional stop functions must be handled by external circuitry because the module does not include an integrated safety option. The module also does not include additional fieldbus masters, so coordination between drives remains on the existing cross-communication interface.
