Product Description:
The CSB02.1A-ET-EC-EC-NN-NN-NN-AW is a drive controller produced by Bosch Rexroth Indramat and delivered within the CSB Drive Controllers series. It coordinates servo axes in factory lines by processing field data, closing position loops, and issuing torque commands to attached power sections. Inside an automation cabinet, it functions as the central signal processor, linking sensors, feedback encoders, and higher-level PLC or motion controllers over Ethernet-based networks.
Its analog front end includes one differential channel with a bandwidth of 1.3 kHz, allowing low-latency capture of process variables over the plus-or-minus 10 V range. This input is digitized at 14-bit resolution so the controller can distinguish 16,384 discrete voltage levels for fine closed-loop regulation. There are 7 digital inputs, which permit state monitoring of limit switches, drive-enable signals, or other binary events. Each of these lines recognizes an ON state once the voltage exceeds 15 V, which matches standard 24 V control circuits and filters out electrical noise. For position feedback, two independent channels accept 2 × Multi-Encoder formats, letting the device read absolute or incremental encoders simultaneously and support dual-loop or gantry synchronization.
On the communication side, the controller carries 2 RJ-45 ports that operate on the 100Base-TX standard, enabling daisy-chain or ring topologies over standard Cat-5e cabling while sustaining deterministic Multi-Ethernet protocols. Two backplane bays provide 2 optional slots, so application-specific modules such as additional I/O or safety cards can be added without enlarging the footprint. No integrated safe-torque-off or related features are present; the safety technology field is marked Not Equipped, which means external safety relays or PLCs must handle emergency stop functions when this controller is integrated into a machine.
