Product Description:

The CSH01.1C-SE-EN1-NNN-NNN-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Integrated into IndraDrive hardware, it supervises axis motion, field I/O, and embedded safety functions in automated machinery. By merging network, analog, resolver, and discrete channels, the unit converts supervisory commands into drive-level signals and returns real-time status to the plant PLC.

The analog interface accepts differential signals within ±10 V, and its input circuitry presents 160 kΩ of typical resistance to protect upstream transducers from excessive loading. Outbound reference values are generated across a 0 to 5 V span with a maximum sourcing capability of 1 mA, enabling direct connection to standard drive enable or speed setpoint pins. All discrete channels share a common supply that can be fed with DC 19 to 30 V, so the controller can be powered from typical 24 V cabinet buses. The EN1 board furnishes resolver excitation at 18.2 Vpp and captures the returned sine-cosine signals, while the same circuitry can interpret Resolver / HSF encoders. Safety Technology I/O terminals include a relay contact rated for DC 24 V / 1 A, providing hardwired axis shutdown.

Network communication is handled through SERCOS II, giving deterministic bus cycles for multi-axis synchronization. Twelve digital inputs trigger reliably at 24 V / 3 mA, and eight transistor outputs can switch loads up to 24 V / 0.5 A, allowing direct actuation of sensors, brakes, or indicators without auxiliary relays. The power budget is low; the EN1 encoder board draws 6 W, the SE safety extension consumes 2 W, and the S1 logic option needs 1 W, minimizing heat inside compact control cabinets. Resolver conversion is clocked at 4 kHz, supporting high-speed position loops even at elevated motor speeds. When combined with the safety layer, the module delivers safe torque off while preserving standard motion performance.
