Product Description:

The CSH01.1C-S3-ENS-MA1-MD2-L2-S-NN-FW is a control section designed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a modular controller, it plugs into IndraDrive power sections and supervises servo axes, motion profiles, and peripheral I/O within industrial automation cells. The device’s role is to exchange real-time data with drives and higher-level PLCs so that positioning, speed, and torque commands remain synchronized across complex machinery.

Communication between the control section and the drive network is handled over SERCOS III, giving deterministic cycle times for coordinated motion. While active, the electronics dissipate only 7.5 W, limiting cabinet heat buildup. Integrated encoder supply rails deliver 11.6 V at up to 500 mA, allowing most indirect or absolute feedback devices to be powered directly from the card. A certified safety layer provides the Safe Torque Off function, enabling immediate removal of motor torque through hardware gating without shutting down the entire controller. At 1000 kHz, the SSI feedback port supports reliable transmission over cables up to 40 m, so remote encoders can be accommodated in large machines.

The MA1 option board equips two analog input channels and two analog output channels, each scaled for ±10 V processing. Inputs are protected by a 1000 kΩ impedance and digitized with 12-bit resolution, while outputs present a 1 kΩ minimum load and use the same resolution. Both directions share matching range symmetry, easing loop tuning for external amplifiers or sensors. The MD2 module contributes 16 digital inputs and the same number of digital outputs, enabling status capture and actuator control without additional field wiring. These I/O resources let the controller connect directly to pressure transducers, potentiometers, limit switches, and interlock relays.
