Product Description:

The CSH02.1B-ET-EC-NN-L3-NN-NN-FW is an axis controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in a drive cabinet, it coordinates multiple servo power sections through an integrated Multi-Ethernet port and processes encoder feedback in real time. By combining network communication, local current loops, and flexible input resources, the unit directs motion sequences for packaging lines, material-handling gantries, and other precise automation cells.

Three analog inputs are sampled at 13 bit resolution, while two analog outputs refresh every 750 µs with a granularity of 24 mV per increment. Deterministic fieldbus exchange occurs on a 250 µs communication cycle over the network interface, and the internal current regulation updates every 62.5 µs to maintain tight torque control. The controller offers eleven digital inputs, five configurable digital I/O channels, and two probe inputs for edge-triggered position capture. A multi-encoder interface supports incremental, SSI, and EnDat feedback formats, and optional slots accept fieldbus, memory, or functional safety extensions without altering the base hardware layout.

The encoder supply rail can deliver 500 mA, and the L3 logic rail supplies 350 mA for peripheral sensors. Integrated safety circuitry implements Safe Torque Off, allowing rapid energy isolation to connected drives. The module gathers process variables through its analog channels, probe inputs, and discrete inputs without supplemental cards. Its configurable I/O points can be mapped as outputs for valve actuation or as inputs for limit switches, and the analog outputs share the same conversion window to maintain synchronization. The option slots, encoder interface, and Ethernet communication operate concurrently to support complex multi-axis machinery.
