Product Description:

The CSH01.1C-SE-EN1-NNN-MA1-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit is mounted on an IndraDrive power stack and acts as the central processor that translates SERCOS network commands into real-time axis signals. By combining high-speed communication with resolver-based position feedback, it coordinates multi-axis motion tasks such as pick-and-place, spindle control, and gantry synchronization in industrial automation cells.

The controller’s internal electronics draw 7.5 W at idle, while the optional analog I/O board adds 2 W, so cabinet thermal sizing can be planned precisely. Two analog input channels accept signals with a full-scale range of ±10 V and are digitized at 12-bit resolution; this permits proportional speed or pressure references from external sensors. Two corresponding analog outputs drive valves or external drives across the same range. SERCOS II is the primary fieldbus and can transmit cyclical data at up to 16 MBaud, giving the axis processor enough bandwidth for sub-millisecond setpoint updates. Command packets are buffered by the controller and routed to the IndraDrive power stage through the backplane, while any installed option cards must be included in the 24 V DC supply budget.

The encoder interface supports resolver and HSF transducers. For resolvers, it sources 8 V to the sensor and excites the reference winding with 18.2 Vpp at 4 kHz, then processes the returned sine and cosine signals; this front end adds 6 W to the module’s dissipation figure. Integrated Safe Motion technology enables functions such as safely limited speed and safe stop without external relays, and the feature set relies on the real-time position data delivered by the feedback channels. When analog outputs, fieldbus links, and resolver supplies are active simultaneously, the controller still operates within the combined option power limits already noted.
