Product Description:
The CSH02.1B-ET-EC-NN-SB-DA-NN-FW is an industrial motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This unit consolidates axis coordination, high-speed feedback processing, and field-level communication so that servo drives, sensors, and supervisory PLCs remain synchronized. Deployed inside packaging lines, material-handling stations, or assembly cells, it forms the computational core that executes interpolation tasks while simultaneously routing process data over deterministic Ethernet networks.
The controller operates from a supply rail of 24 VDC, and its internal electronics draw a base power of 17 W, which is useful for cabinet thermal calculations. Signal acquisition begins with 3 analog inputs that accept process variables, while two analog outputs can retransmit scaled setpoints. The controller has 11 digital inputs to capture status bits from photo-eyes or limit switches, and five configurable digital I/O lines allow each point to be programmed as an input or output to simplify wiring changes. For network traffic, the hardware presents Gigabit-capable ports, and 2 can be daisy-chained in a line topology that complies with the IEEE 802.3 Ethernet standard. Dedicated ET, EC, and SB option modules add 2.7 W, 1.1 W, and 2.5 W respectively to the power budget, values that are included when sizing the cabinet supply rail.
Regulation loops run quickly: the drive stage updates phase currents every 62.5 µs, adjusts velocity every 125 µs, and refines position every 250 µs. These deterministic cycles minimize following error on rapidly accelerating axes. At initial energization, the controller’s input filter limits surge current to less than 5 A and restricts the pulse width to 1 ms, protecting upstream supplies. Because each loop and safety threshold is executed in hardware, program execution time is not affected by user logic, leaving unused bandwidth available for additional motion tasks.
