Product Description:
The CSB02.1A-ET-EC-EM-L3-NN-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed on the left side of a modular servo drive stack, it provides the processing, fieldbus handling, and safety logic that direct the associated power section. Within automated assembly lines or packaging stations, the unit converts command data into real-time axis signals so that motors follow programmed motion profiles precisely. It occupies a single slot width inside the drive rack and plugs into any power section through a card-edge connector, reducing wiring.
One analog channel is processed at 14-bit resolution, giving fine setpoint granularity for speed or torque loops. Seven digital inputs and a single configurable DIO line accept limit switches, homing sensors, or handshake flags. The logic electronics are powered from a 24 V DC control supply, while the high-side transistor stage can source up to 500 mA on its single digital output. A MultiEthernet interface links the controller to master PLCs and supports virtual feedback generation that emulates incremental RS-422, single-ended, and SSI encoder formats for connected position devices.
Device integration is simplified because the Ethernet port can switch among Sercos III, EtherCAT, PROFINET IO, EtherNet/IP, and POWERLINK without additional hardware. When combined with HCS02, HCS03, HMS01, or HMS02 power modules, the control section forms a complete drive solution. Functional safety attains Category 4 PL e/SIL 3 by means of a hardware-wired Safe Torque Off channel that removes gate signals during emergency events. A standard control panel on the front provides parameter access and fault codes, and the lightweight enclosure tips the scale at 0.480 kg, easing mounting on DIN rails or within tight cabinets.
