Product Description:

The Bosch Rexroth Indramat CSH01.1C-ET-EN2-NNN-MA1-S2-S-NN-FW belongs to the CSH Advanced Controllers series of modular drive control units. As a control section, it hosts analog conversion, safety outputs, and Ethernet, allowing a drive to coordinate motion axes and report status to higher-level PLCs. Internal encoder supply rails rated at 350 mA power feedback devices directly, while analog I/O pins accept reference voltages or generate command signals for the attached power section. The device mounts inside the drive stack with minimal panel wiring.

Each analog input accepts dynamic signals up to 1 kHz, so rapidly changing signals can be captured without aliasing. The input path presents a resistance of 1000 kΩ, and this high impedance helps prevent loading errors on connected transducers. Conversion resolution is 5 mV/inc, allowing the controller to detect small voltage differences for precise closed-loop regulation. An analog output can source up to 10 mA into a minimum load of 1 kΩ, so proportional valves or external recorders can be driven without additional buffers. For networked data exchange, the controller follows the 100Base-TX Fast Ethernet standard, and with twisted-pair cabling, segments can extend to 100 m without repeaters.

Electrical demand is modest, as the control electronics draw 7.5 W at standby, which helps limit cabinet heat rise. Option boards EN2, ET, and MA1 contribute additional draws of 6 W, 2.2 W, and 2 W respectively, figures that help calculate the complete supply budget for the drive stack. A power-up inrush of 4 A must be considered when sizing fuses, yet it decays after the internal capacitors charge. The safe switching channel can deliver up to 0.5 A to field devices, and the logic releases this current after a programmed startup pulse of 100 ms.
