Product Description:

The CSH02.1B-ET-EC-EM-S4-NN-NN-FW is an advanced motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates servo drives and feedback devices in multi-axis machinery where several axes must accelerate, decelerate, and hold position in a synchronized manner. The unit provides deterministic command execution, safety supervision, and network bridging for factory automation cells that depend on repeatable motion behavior and reliable exchange of control data.

During operation, the controller draws from a control supply of 24 VDC while its base power consumption remains at 17 W. This helps keep cabinet thermal load moderate during continuous use and supports installation in compact control enclosures. It provides 2 analog outputs for reference signals to external amplifiers or monitoring hardware and accepts 11 digital inputs for limit switches, sensors, or user pushbuttons at the machine. Time-critical torque regulation is handled by a current control loop executed every 62.5 µs; velocity and position loops follow at 125 µs and 250 µs respectively, so each axis can be tuned for high-bandwidth response during rapid speed changes and short positioning moves. The multi-encoder interface supports absolute and incremental feedback, and encoder emulation terminals duplicate position data for secondary systems such as external monitors or parallel control devices.

On the communication side, the CPU integrates a Multi-Ethernet port stack that negotiates real-time frames across sercos III, EtherCAT, EtherNet/IP, PROFINET IO networks without additional option cards, which lets the controller fit into different automation architectures. Wiring can extend up to 100 m per segment, allowing distributed panels along conveyors or gantries while maintaining standard copper network runs. The built-in Safe Motion architecture supports up to 35 safety nodes and a zone length of 2500 m, allowing extensive protected areas with features such as safe torque off, safe stop, and controlled speed for coordinated machine protection.
