Product Description:

The CSB02.5B-ET-EC-EP-L3-EC-NN-NW is a drive controller module from Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. Designed for multi-axis automation, the device coordinates motion, collects feedback, and relays commands between the motor power section and higher-level PLCs. It serves as the central regulation layer for torque, speed, and position control in compact machinery.

Electrical power for the logic side is supplied at DC 24 V, and the unit mates mechanically and electrically with the HMU05 power section to form a complete axis. Two ±10 V analog outputs support external actuator commands, while eleven dedicated digital inputs and five configurable digital I/O channels accept sequencing signals or status flags. For high-speed edge capture, the controller can process pulses with widths down to 1 ms. Network connectivity is handled through an 8-pin RJ-45 connector that carries a 100Base-TX Ethernet link for real-time control messages. Two probe inputs simplify position latching tasks, a female D-Sub 15-pin connector receives encoder feedback, and three option slots allow fieldbus, safety, or additional I/O cards to be added without increasing the footprint.

Signal conditioning resources address both resolver and analog sensor channels. The resolver interface digitizes position data with a resolution of 12-bit, and the internal analog front end presents a 120-ohm input for sine reference signals while attenuating content above a 400 kHz cutoff. Square-wave tracks are accepted up to 1000 kHz, so the controller can follow fast-rotating feedback devices without losing edge fidelity. When a multi-Ethernet option is installed, the communication circuitry draws only 2.7 W, leaving more of the cabinet supply available for sensors and relays. This supports deterministic cycle timing in packaging, printing, and pick-and-place machines that require very fast position updates.
