Product Description:

The CSB02.5B-ET-EC-PB-NN-EM-NN-NW is a drive controller unit produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. Within a multi-axis motion system, a controller of this type handles closed-loop command processing between the machine’s PLC layer and the attached power section, enabling synchronous motor operation and coordinated positioning tasks on automated machinery. The controller mates with the HMU05 power section so that axis modules receive synchronized command data through the internal bus without separate cabling.

It operates from a supply voltage of 24 V DC, which powers the internal CPU, I/O conditioning, and fieldbus electronics. The controller provides 11 digital inputs that accept 24 V signals for start, stop, or limit switches. For analog reference loops, it carries 2 ±10 V outputs, each isolated for command of external drives or transducers. Five points can be configured as digital inputs or outputs; this flexibility is indicated by 5 configurable I/O channels that allow the board to be adapted to sensor or actuator needs. When the fast probe sequence is triggered, the device can capture input transitions down to 1 ms pulse width, ensuring precise latch registration on high-speed machinery. Two dedicated probe inputs support edge capture, while 1.2 W of encoder emulation power maintains simulated incremental feedback for PLC diagnostics.

For networked control, the front panel carries an RJ-45, 8-pin connector that follows the 100Base-TX Ethernet standard, allowing real-time parameter access. Cable runs up to 100 m are permitted without repeaters, which helps keep cabinet placement flexible. The multi-Ethernet circuitry draws only 2.7 W, while a dedicated Profibus module requires 1.1 W when that fieldbus is enabled. A D-Sub 15-pin female socket is provided for direct motor encoder feedback, ensuring shield continuity through a single connector.
