Product Description:
The CSH01.1C-S3-EN2-NNN-MD2-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive power module, it executes position, velocity, and torque loops while exchanging real-time data with higher-level PLCs. By coordinating encoder feedback, field I/O, and drive power, the board serves as the core motion processor in automated packaging, handling, and metal-cutting systems. Because the control section is integrated into the power module, signal paths remain short and the overall axis package stays compact inside the drive cabinet.
Communication with the drive train relies on the industrial Ethernet protocol SERCOS III, exposed on an RJ-45, 8-pin port for straightforward cabinet wiring. The analog monitor channel presents an input resistance of 160 kΩ, preventing signal loading by external transducers. Core electronics draw only 7.5 W, minimizing cabinet heat. The second encoder interface (EN2) supplies 5.0 V to feedback devices and terminates differential pairs with 120 Ω for noise immunity; its own consumption is 6 W, and up to 350 mA is available to the sensor. Position data can arrive as EnDat 2.1, 1 Vpp, or 5 V TTL signals, letting one card accept both analog and digital encoders without add-on hardware. The dedicated encoder supply and termination help maintain stable feedback quality over typical industrial cable runs.
The EN2 signal path is bandwidth-limited at 500 kHz for sine channels and accepts square-wave feedback up to 1000 kHz, supporting high spindle or conveyor speeds. The MD2 expansion offers 16 opto-isolated digital inputs plus an equal number of sourcing outputs, each rated at 24 V / 0.5 A for direct actuation of valves or contactors; a dry relay rated 24 VDC / 1 A is provided for auxiliary switching. Integrated safety technology designated Safe Motion enables certified monitoring of speed and position without external relays, simplifying compliance with machinery safety standards while allowing the controller to supervise motion, field signals, and safety functions from a compact drive slot. This arrangement lets the drive respond directly to interlocks and machine signals within the same axis-control platform.
