Product Description:

The CSH02.5B-CC-EC-ET-L3-EC-NN-NW is a drive and motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in multi-axis machines, the unit coordinates servo inverters through its integrated Sercos and Ethernet channels, translating program commands into synchronized torque, speed, and position outputs. By combining logic processing with encoder acquisition and safety shutdown, it serves as the central control element in automated assembly lines, packaging equipment, and material-handling cells. Its modular housing mates directly with HMU power units, reducing cabinet wiring.

I/O capacity supports field devices directly. The controller offers 11 digital inputs for fast signal capture, while five channels can be configured as either inputs or outputs to match sensor or actuator requirements. The unit provides 3 analog inputs for ±10 V process variables and 2 analog outputs for drive setpoints. Each transistor output can source up to 500 mA, and relay contacts carry 1000 mA at up to 30 V for higher-power loads. Two probe inputs latch position values with a minimum pulse width of 4 µs, making them suitable for registration marks and print synchronization. Communication with subordinate drives is handled by the Sercos III master port, and a dedicated STO circuit provides the Safe Torque Off (STO) function without affecting parameter data.

Encoder feedback reaches the primary and additional interfaces, and each interface accepts Multi-Encoder formats. Network coupling to higher-level PLCs is handled through the Multi-Ethernet secondary interface, which transports EtherNet/IP, PROFINET, or EtherCAT telegrams without extra hardware. Three spare slots allow user-selected option cards for extra communication, memory, or safety functions. The HMU05 power section supplies internal logic voltage and locks mechanically to this module, forming a compact drive stack that conserves panel space.
