Product Description:

The CSH02.1B-CC-EC-EM-S4-NN-NN-FW is a compact motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The module installs in a control cabinet and supervises drive axes, local inputs, and fieldbus traffic. By issuing time-critical current, speed, and position commands, it links higher-level PLC logic with servo amplifiers in assembly lines, pick-and-place units, and other automated machinery.

For built-in I/O, the module provides 11 digital inputs rated for 24 V signaling, enabling direct connection of proximity sensors and limit switches without external adapters. It also has 5 configurable digital I/O channels that can operate as sourcing outputs or as additional inputs when parameterized. Two differential voltage stages provide 2 analog outputs (±10 V), allowing the controller to send reference values to external actuators or process instrumentation. Data exchange with drives occurs over a single fiber ring because the controller operates as a Sercos III Master, and system adaptation is supported by 3 optional slots for encoder evaluation cards, fieldbus bridges, or added memory.

Axis regulation routines run on dedicated processors inside the module. The position loop is refreshed every 250 µs, while the torque loop uses a 62.5 µs current control cycle and the speed loop uses a 125 µs velocity control cycle, supporting high dynamic accuracy during rapid motion sequences. Safety-related shutdowns are managed through the Safe Motion interface on Interface 3, allowing the controller to exchange STO, SS1, and similar signals with certified peripherals. Two probe channels capture encoder position on external trigger edges, Interface 4 is not fitted, and the housing weighs only 0.480 kg unpacked, which helps simplify installation in compact control cabinets.
