Product Description:
The CSB02.1A-ET-EC-EP-L3-NN-NN-AW is a drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. In modular automation cells, it coordinates servo axes and collects local I/O while forwarding status data to higher-level control networks. By combining embedded power electronics with field communication, the unit regulates current, velocity, and position loops for attached motors. Its compact size and low static power requirement allow installation inside decentralized electrical panels.
The controller operates from a nominal DC 24 V control supply and draws only 17 W under standby conditions, so auxiliary power supplies remain lightly loaded. Field communication is managed through a Multi-Ethernet interface that automatically identifies protocol stacks such as EtherNet/IP or PROFINET while maintaining the physical layer bandwidth of 100Base-TX. The unit provides 7 digital inputs, along with one analog channel and one configurable input that can be assigned as a quick reference or enable signal. Two probe inputs latch encoder position for time-critical measurement tasks, and two optional slots accept expansion modules when additional networking or safety hardware is needed.
Motion feedback devices plug into the Multi-Encoder Interface, which supplies 500 mA at both 5 V and 12 V to power resolver, incremental, or EnDat sensors. The Safe Motion architecture integrates the certified Safe Torque Off channel; when activated, it removes gate signals to the drive stage without altering parameter memory. During power-up, the input stage limits inrush to <5 A for a maximum of 1 ms, preventing nuisance trips on oversensitive supplies. Network wiring is completed through a shielded RJ-45, 8-pin connector, and internal diagnostics forward link status as soon as conductors are connected.
