Product Description:
The CSB02.1B-ET-EC-EM-L3-NN-NN-AW is a modular drive controller section produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. Installed beside a power unit, it forms the logic layer that interprets motion commands, acquires feedback, and dispatches drive signals. Within automated packaging, assembly, or handling cells, this control section translates network traffic and local I/O into real-time torque requests, allowing servo axes to hold position, accelerate, or decelerate according to programmed profiles.
Three differential analog channels accept command voltages over a range of ±10 V, letting external process controllers issue speed or torque references directly to the board. Conversion accuracy on the two analog outputs is fixed at 24 mV/incr, and each channel can swing the same ±10 V span to retransmit scaled setpoints to downstream devices. The section provides 3 analog inputs and 2 analog outputs, complemented by 11 digital inputs for fast on and off events such as limit switches. All low-level electronics run from a regulated DC 24 V supply that is delivered through the backplane. A multi-encoder interface converts signals from resolvers, EnDat, or Hiperface transducers and can output absolute or incremental images to follow drives. During power-up, the controller limits inrush current to less than 5 A for a 1 ms interval.
A Multi-Ethernet port negotiates EtherNet/IP, EtherCAT, or PROFINET frames so higher-level PLCs can parameterize axis functions, while internal SSI emulation drives leave the slot at 1 MHz for synchronous position latching. Integrated Safe Torque Off circuitry disconnects gate drive energy without relying on external contactors, reducing reaction times and wiring. Relay contacts on the board can switch up to 1000 mA for brake release or status signaling, and overall logic consumption never exceeds 19.2 W, allowing dense installation without extra cooling.
