Product Description:
The CSH01.1C-PB-EN1-NNN-MD1-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed inside IndraDrive automation platforms, it acts as the primary processing node that evaluates feedback, manages fieldbus traffic, and issues motion commands to the power stage. By integrating analog, digital, and Profibus interfaces on one compact board, the unit streamlines axis coordination, safety interlocks, and process sequencing within industrial machinery such as packaging lines, handling gantries, and printing presses.
Its analog front end offers an input resistance of 160 kΩ, allowing precise voltage sensing while minimizing the load on external transducers. Each input is quantized at 1.23 mV/inc, and the corresponding output channel provides a resolution of 19.5 mV/inc for proportional command signals. The controller draws only 7.5 W under base load, yet it can withstand an inrush of 4 A for as long as 100 ms when the drive cabinet is energized. On the MD1 expansion, 12 digital inputs capture fast limit-switch or sensor states, while eight transistor outputs can source up to 500 mA each for solenoids or indicator lamps. This combination of low steady-state power demand and high-density I/O supports compact multi-axis systems where panel space and heat dissipation are constrained.
High-speed communication is handled by a Profibus DP interface that reaches a maximum rate of 12 MBaud, enabling synchronized data exchange between the controller and higher-level PLCs. For safety-related functions, the HSF channel presents 10 kΩ of input resistance and is energized by 8 VDC, ensuring reliable monitoring of emergency-stop circuits. Two onboard relay contacts can switch 1 A DC at 30 VDC for brake release or power-enable logic. Motion feedback channels supply 4 kHz excitation to resolver transducers, with a peak-to-peak drive of 18.2 Vpp that maintains signal integrity over long motor cables.
