Product Description:
The CSH02.1B-CC-EC-CN-L3-NN-NN-FW motion logic controller is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It coordinates multi-axis drives, process signals, and fieldbus data in automated machinery, acting as the central unit that links feedback devices with higher-level PLCs. Within a compact housing, it handles real-time motion calculation, local I/O management, and network supervision. This arrangement supports cabinet layouts on assembly lines, packaging platforms, and material-handling cells while reducing wiring complexity. Because feedback handling and network control are integrated in the same unit, command flow between the machine controller and connected axes remains direct.
A 5 V encoder rail supplies 500 mA, so several position transducers can be powered directly, and signals are acquired through a multi-encoder interface that accepts incremental and absolute formats. Two analog outputs deliver control voltages over a span of ±10 V and can drive loads as low as 2 kΩ. Five configurable digital I/O points and two probe inputs support switching tasks and fast event capture. The controller executes current-loop calculations every 62.5 µs when operating as a Sercos III master, and its CANopen interface can manage up to 127 subordinate nodes. This combination allows one controller to handle both drive-level regulation and peripheral device communication within the same machine section.
Trajectory data is refreshed every 250 µs, and speed corrections follow every 125 µs, helping maintain tight axis coordination during interpolated moves. The unit offers 11 discrete inputs for limit switches, sensors, or user buttons, while the two probe lines record precise edge positions during calibration routines. CANopen support simplifies wiring to distributed valves or remote I/O, and the safety layer incorporates Safe Torque Off so power can be removed from connected drives without extra contactors. Three optional slots allow expansion with additional encoder channels or fieldbus boards, which gives the controller more interface flexibility for different machine layouts.
