Product Description:

The CSH01.1C-SE-ENS-NNN-MD2-NN-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed in an IndraDrive power module, it supervises closed-loop motion tasks and field signal processing for automated machinery. The board combines bus, encoder, and discrete I/O resources, letting a single slot coordinate axes, manage velocity profiles, and forward status data to higher-level PLCs or SCADA hosts in production cells.

Two differential analog channels accept command signals within ±10 V and present an input resistance of 160 kΩ, minimizing load on upstream transducers. Real-time drive commands and diagnostic telegrams move across the SERCOS II fiber-optic ring, isolating control data from plant noise. Feedback from position encoders enters through a front-panel 15-pin female D-Sub connector that supports the Standard Encoder Evaluation interface, while the sensor electronics receive a regulated 12 V supply sourced on the card. A separate Mini-DIN 8-pin socket provides access to the RS-232 service channel for parameter backup, and no integrated safety technology is included on the control section.

The communication ASIC clocks the SERCOS telegrams at a maximum of 16 MBaud, supporting multi-axis update cycles of less than one millisecond. On the MD2 mezzanine, the section provides 16 digital inputs and an equal number of sourcing outputs, and each output can switch up to 0.5 A for valve coils or interposing relays. For higher-current devices, a dedicated form-C relay is available and is rated at 24 V DC, 1 A. The Option 3 slot is populated with a Digital I/O and SSI evaluation module, adding a 24 V supply for synchronous serial encoders and permitting absolute position capture without external converters. Because there is no onboard safety logic, any safety-rated functions must be handled by external circuitry.
