Product Description:

The CSH01.1C-ET-EN1-NNN-NNN-S2-S-NN-FW is a motion logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It mounts inside drive packages where it coordinates servo axes, acquires field data, and routes commands between the machine PLC and the power section. By combining encoder evaluation, analog sensing, and fieldbus handling in a single slot, the unit functions as the processing layer for industrial automation that demands synchronized multi-axis positioning. This arrangement allows the controller to centralize motion tasks that would otherwise require separate interface modules, reducing wiring between feedback devices, command sources, and the associated drive electronics.

The controller accepts one differential analog input scaled for a range of ±10 V, which lets external speed or torque references be read without extra conditioning. That channel presents an input resistance of 160 kΩ, so it places minimal load on connected sensors. Two analog outputs are available, and each can source 5 V / 1 mA for tachometers or external limit indicators. Real-time exchange with higher-level networks is handled through a Multi-Ethernet interface that follows the 100Base-TX physical layer and is presented on 2 × RJ-45 connectors. Seven dedicated digital inputs, four software-selectable digital I/O points, two probe inputs, and a resolver plus HSF encoder channel complete the signal set for fast position capture. The available signal mix supports reference input, status reporting, and fast event detection on one control platform, which helps the drive react quickly to machine commands and feedback changes.

The resolver interface excites the transducer with 18.2 Vpp at a carrier frequency of 4 kHz, securing reliable angle feedback even on long cable runs. Integrated safety is provided by the controller’s Safe Motion technology, enabling certified functions like safe limited speed when paired with compatible drives. Two relay outputs are included, and each contact can switch up to DC 24 V / 1 A; these contacts are typically mapped to diagnostics or process alarms. This combination supports machine interlocks and status forwarding without requiring an external relay board for basic alarm handling. With additional configurable digital outputs and multi-protocol messaging, the CSH01.1C variant supervises complex axes while conserving cabinet space.
