Product Description:

The CSH01.1C-S3-EN1-NNN-NNN-L2-S-NN-FW control section is part of the CSH Advanced Controllers series from Bosch Rexroth Indramat. Designed for IndraDrive drive stacks, this controller manages precise motion sequences for servo axes in automated machinery. It consolidates fieldbus exchange, encoder processing, and safety circuitry on a single board, enabling centralized axis regulation for packaging, material-handling, and light machining systems in compact cabinet layouts. This integration helps reduce wiring and setup time.

The analog front end presents an input resistance of 160 kΩ, so the board can sense low-energy process signals without loading them. Each channel accepts an input span of ±10 V, matching standard instrumentation transmitters. Two analog outputs are available, and each can source up to 5 V / 1 mA, providing reference values to external actuators or drives. Internal consumption is limited to 7.5 W, which simplifies thermal planning inside slender control cabinets. Axis commands and diagnostics move over SERCOS III, giving deterministic real-time exchange with upper-level motion controllers. Additional links include an RS232 service port for parameter access and an encoder evaluation block that supports HSF and resolver feedback from MHD or MKD motors.

Sixteen digital inputs switch reliably at 24 V / 3 mA, while eight digital outputs can drive solenoids or contactors up to 24 V / 0.5 A. Integrated safety includes Safe Torque Off, enabling immediate energy removal from the power stage without external relays. The S3 communication module supports 100Base-TX for service or diagnostic data, and it draws only 1 W from the logic supply; companion modules EN1 and L2 require 6 W and 2 W respectively. This separation lets builders size auxiliary supplies accurately while keeping overall cabinet dissipation predictable.
