Product Description:

The CSH01.1C-SE-ENS-EN2-MD2-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed inside IndraDrive power units, this module manages motion commands, safety logic, and feedback processing for one servo axis on industrial machinery. It serves as the command-processing layer between the higher-level automation system and the power section, translating setpoints into internal control actions for the connected motor. By combining fieldbus communication, encoder evaluation, and configurable I/O in a single plug-in board, it coordinates torque, speed, or position loops for packaging, handling, and metal-forming equipment.

This version is configured for single-axis operation, so all control resources are concentrated on one drive channel. Real-time exchange with the drive amplifier and neighboring nodes takes place over SERCOS II, and the optical layer uses fiber-optic cables to preserve signal integrity in electrically noisy cabinets. Using optical communication helps reduce susceptibility to electromagnetic interference from switching devices, motor leads, and other high-current components mounted in the same enclosure. Two encoder ports are provided; the first supplies 12 V for incremental or absolute sensors, while the second can source up to 350 mA to power higher-load transducers. The standard single-line control panel on the front edge permits local parameter access and basic diagnostics without removing the unit from service.

In addition to motion channels, the MD2 expansion embedded on this board presents 16 inputs and 16 outputs through a 24 V sink or source interface. The digital lines let the controller exchange status signals with external devices such as sensors, interlocks, and simple machine actuators. This arrangement supports direct connection of basic machine signals without a separate I/O card. Integrated safety follows the Rexroth S1 concept, and the safe outputs can switch loads up to 24 V / 0.5 A for emergency-stop chains or gate interlocks. A dedicated RS232 service port allows parameter access when a SERCOS network is not yet active.
