Product Description:

The CSH01.1C-NN-EN1-EN2-MD1-NN-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a compatible Rexroth drive stack, the module handles axis positioning, feedback evaluation, and field-level I/O so the inverter can perform closed-loop motion tasks. By combining two encoder channels, onboard digital I/O, and a small built-in display, the controller supports setup and runtime diagnostics in automated machinery such as packaging lines and material-handling cells. This arrangement lets one control section manage motion feedback and local signal handling without requiring separate interface hardware for every machine function.

The module has a base power consumption of 7.5 W, which is the steady energy taken from the shared DC bus when no external loads are active. A brief inrush of 4 A occurs at startup, so that surge must be considered by the upstream protection circuit. Timing-critical outputs observe a maximum pulse width of 100 ms, which limits how long the controller can energize an output during short command events. The MD1 expansion includes 12 × 24 V digital inputs for sensor states and 8 × 24 V transistor outputs for solenoids or relays. This allows the drive to react directly to field signals and switch external devices through the integrated I/O section.

The second encoder port uses an auxiliary supply of 5 V, allowing EnDat 2.1, 1 Vpp, or TTL feedback devices to report position without a separate power feed. Parameter access is handled through the legacy-compatible RS232 serial interface, which supports bench testing with standard cables. Resolver feedback is supplied by a dedicated DC 8 V carrier and an AC 18.2 Vpp, 4 kHz excitation signal, keeping analog feedback support separate from the module’s digital control functions. These signal and supply paths allow the controller to work with multiple feedback formats while maintaining direct service access through the serial connection.
