Product Description:

The CSH01.1C-SE-NNN-NNN-MD2-NN-S-NN-FW is a motion-logic controller module from Bosch Rexroth Indramat in the CSH Advanced Controllers series. The unit plugs into IndraDrive control racks and coordinates multi-axis drives, translating high-level machine commands into deterministic drive signals for automated packaging, printing, and material-handling cells. It provides the processing core for interpolation, feedback handling, and controlled shutdown functions within an industrial automation line. This role allows the controller to manage coordinated motion tasks while keeping communication between the control level and the drive level organized and responsive.

The first analog channel accepts a differential input of ±10 V and has an input impedance of 160 kΩ, so connected signal sources are not heavily loaded. On the output side, the digital-to-analog converter updates every 10 µs, and each increment equals 19.5 mV/inc, which supports fine command resolution for torque or velocity references. Control electronics draw power from a regulated 24 V DC supply, and the typical inrush current briefly rises before settling to continuous consumption. The analog section remains stable during startup because the inrush interval is isolated from the signal grounds, helping the controller maintain clean reference behavior during power application.

Fieldbus exchange with the drive stack takes place over the fiber-optic SERCOS II interface, which supports deterministic data transfer for the Md2 I/O section. The Md2 digital inputs and outputs are rated at 24 V / 0.5 A, allowing the module to interface with common industrial control signals used around a drive system. During power-up, relay contacts withstand a 100 ms inrush pulse without sticking, and total controller dissipation remains below 7.5 W, which helps limit heat buildup inside the cabinet. The Md2 section can also source current for encoders and grouped outputs, while position feedback devices connect through an RJ12 6-pin socket for direct integration with the motion system.
