Product Description:

The CSB02.1A-ET-EC-EC-NN-NN-NN-FW is a drive controller module built by Bosch Rexroth Indramat for the CSB Drive Controllers series. It functions as the central control electronics for servo axes, translating command data from higher-level automation systems into regulated current and voltage for connected power stages. By integrating high-speed I/O, encoder evaluation, and Ethernet communication in one housing, the unit coordinates position, speed, and torque loops in machinery such as packaging stations, pick-and-place gantries, and material-handling lines.

The analog front end includes one ±10 V input with a 1.3 kHz bandwidth, and it resolves incoming signals at 14-bit resolution to minimize quantization error. Electrical noise is suppressed because the differential stage provides 50 dB of common-mode rejection. For discrete control tasks, the board offers 7 digital inputs, each scanned in real time to capture limit-switch or sensor states. Motion feedback can be connected through two encoder interfaces, while two dedicated probe inputs time-stamp edge events for position capture. Internal logic and I/O are powered from 24 V DC, allowing the controller to remain active during main power outages.

Network integration relies on the Multi-Ethernet port that conforms to 100Base-TX signaling; when paired with a CAT5e (ITP) cable, the link may be routed up to 100 m without repeaters. The media terminates on an 8-pin RJ-45 connector. Two optional slots accept expansion cards, and the unit supports two relay outputs whose contacts close after a 10 ms pick-up delay and can switch up to 30 V for auxiliary circuits. The probe inputs and the pair of encoder channels share time-stamp logic, enabling synchronized capture across multiple axes while maintaining deterministic Ethernet communication for coordinated motion control.
