Product Description:

The CSH02.1B-ET-EC-EC-S5-EC-NN-FW is a motion and machine controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed between a plant-level PLC and multiple drive modules, it interprets trajectory data, supervises feedback, and distributes time-critical telegrams so automated packaging, handling, or printing stations keep tight positioning tolerances. The unit is housed as a rack-mountable card set that plugs into the power section of an IndraDrive cabinet.

The controller draws logic power from a 24 V DC supply and interfaces with higher-level networks through Multi-Ethernet ports that comply with IEEE 802.3. Message frames refresh every 250 µs, while the inner current loop closes in 62.5 µs; a velocity loop of 125 µs and a position loop of 250 µs complete the cascaded architecture. Two analog outputs deliver reference voltages to external actuators, and three analog inputs are provided for process variables such as force or tension. Internal data can be expanded through optional plug-in cards without enlarging the footprint. Control code can trigger two probe inputs for registration marks, enabling precise print-to-cut synchronization.

The digital section offers 11 24-volt inputs for limit switches or sensors and can source up to 500 mA on its transistor outputs. Position feedback is accepted via 3 encoder interfaces that recognize EnDat, Hiperface, or incremental signals, allowing direct connection of linear or rotary encoders. Integrated Safe Motion technology supervises speed, standstill, and direction to meet category-oriented safety requirements. Three optional slots accommodate fieldbus, I/O, or memory cards, and two probe inputs support high-resolution capture of edge events. A relay block rated for 100,000,000 mechanical cycles handles auxiliary contact tasks in high-duty machinery.
