Product Description:
The CSB02.1B-ET-EC-EC-L3-EM-NN-AW drive controller is manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It is a compact DIN-rail unit that manages one motor axis and coordinates torque, speed, and position loops in automated assembly lines, packaging stations, and material-handling cells. Its compact format suits control cabinets where space is limited but accurate single-axis motion still has to be integrated with surrounding machine logic. By interpreting encoder feedback and issuing precisely timed current vectors, the module links motion tasks to higher-level PLC sequences.
Internally, the controller samples analog feedback with 11-bit current resolution and finer 13-bit voltage resolution. Three analog input channels accept ±10 V or 0–20 mA process signals, while two analog outputs retransmit setpoints to auxiliary drives. This arrangement lets the controller exchange reference and feedback signals with nearby equipment without requiring a separate interface card. Its base power consumption of 17 W limits cabinet heat load. For discrete control, the unit provides 11 digital inputs and five software-assignable digital I/O points. The paired encoder channels support primary motor feedback and an auxiliary measuring path in the same controller. Command traffic moves over the Multi-Ethernet interface, allowing automatic protocol selection among Sercos III, EtherNet/IP, and PROFINET.
Network wiring is handled through an 8-pin RJ-45 connector that operates at 100Base-TX speed, and the drive can supply field devices with up to 500 mA on its digital output line for relays or status lamps. The Ethernet connection uses standard twisted-pair cabling, which helps simplify integration into existing machine networks. Motion disable is achieved through the certified Safe Torque Off function, which interrupts gate firing without relying on contactors. An additional port provides encoder emulation pulses for legacy counters, which supports integration with older positioning systems.
