Product Description:
The CSB02.1B-ET-EC-EC-NN-EM-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It combines motion control, fieldbus networking, and local I/O handling to command servo axes in packaging, material-handling, and assembly lines. The unit converts higher-level setpoints into precise current and velocity profiles for connected motors, while its compact housing and integrated power section minimize cabinet space and external wiring. Two built-in expansion bays support application-specific modules as machine demands evolve.
Control communication is handled through Multi-Ethernet, allowing the same hardware to switch between SERCOS over Ethernet, EtherNet/IP, PROFINET, or EtherCAT profiles without module changes. Physical networking is provided by 2 Ethernet ports, each rated for 100Base-TX throughput and terminated on a single RJ-45, 8-pin connector block that snaps into the front panel. Signal interfacing is equally dense: the controller offers 11 digital inputs for limit switches, sensors, or PLC flags, while two probe inputs capture encoder positions with sub-microsecond precision. Two EC expansion modules are factory-installed to process high-resolution encoder formats, and a single EM module supports EMC-optimized wiring by conditioning feedback and power lines.
Process feedback and actuator drive can be scaled through 2 analog outputs that supply ±10 V reference signals for external amplifiers or proportional valves. For machine sequencing, 5 configurable digital I/O points can act as outputs for solenoid drivers or as auxiliary inputs when PLC capacity is limited. Electromagnetic compatibility is aided by a cable capacitance limit of 60 pF/m on the EM feedback channel, reducing signal distortion on long motor leads. The unit is not equipped with integrated safety technology, so external safety relays or PLC-based SIL devices must be added if risk reduction is necessary. Two unused optional slots remain available for future fieldbus, safety, or memory modules without enlarging the footprint.
