Product Description:

The CSB02.5B-ET-EC-CN-S4-NN-NN-NW drive controller is produced by Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. Designed to pair with the HMU05 power section, the device governs servo axes in automated cells. It converts feedback and exchanges real-time data with higher-level PLCs to coordinate motion sequences. This arrangement lets one control section handle command processing, feedback evaluation, and axis response within a compact drive architecture.

Its analog section delivers a bipolar output span of ±10 V. The output can be trimmed in 6 mV increments, providing fine resolution for torque or velocity setpoints, and the command-input span remains consistent with the controller output. For networked communication, the unit includes a Multi-Ethernet port that supports several Ethernet-based protocols, allowing the same hardware to fit different plant topologies. Keeping the network interface onboard reduces the need for separate communication hardware in mixed-control environments. Local digital devices draw from a 24 V auxiliary rail inside the controller, and each transistorized channel can sink or source up to 500 mA, so relays, sensors, and light stacks can be powered directly without extra conditioning. The onboard relay contacts can switch loads up to 30 V. Position feedback arrives through a multi-encoder interface that accepts EnDat, Hiperface, and similar formats.

In motion-control applications that rely on differential encoder signals, the EC evaluation channel operates with a bandwidth of 400 kHz and an input impedance of 120 Ω, so high-speed feedback lines remain undistorted over long cable runs. Machine-wide coordination is also possible through the built-in CANopen fieldbus, which complements the Ethernet interface and supports standardized device profiles for drives. The separate encoder and fieldbus resources allow the controller to manage axis feedback and machine-level coordination at the same time. Safety functions are implemented with the Safe Motion package, enabling certified shutdown modes without external relays. During power-up, inrush demand is limited to <5 A for 1 ms, reducing stress on cabinet breakers.
