Product Description:
The CSB02.1B-ET-EC-NN-L3-DA-NN-FW drive controller is produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. Installed as the control section in modular automation systems, it supervises feedback conversion, I/O processing, and network communication for the power stages that energize servomotors. This device coordinates motion trajectories, enforces safety functions, and links the machine to higher-level PLCs through its integrated Ethernet ports.
The control board accepts ±10 V reference levels on its 3 differential analog inputs, so process variables from sensors or potentiometers can reach the drive without external scaling. Output feedback is available through 2 analog outputs, each quantized in steps of 24 mV/incr, giving fine resolution for monitoring loops or test benches. For fast on and off signaling, the unit provides 11 digital inputs that latch within microseconds, and a multi-encoder interface supports quadrature, EnDat, and SSI formats for precise position acquisition. A dedicated digital and analog I/O extension bus allows additional field modules to be attached when channel density must grow beyond the base resources.
For machine variants, the board provides 5 configurable digital I/O points that can be set as inputs or outputs, plus two probe inputs intended for latch or touch-trigger functions. Communication with the cell network occurs on a Multi-Ethernet stack that runs at 100Base-TX speed through an 8-pin RJ-45 connector. Three optional slots accept safety, fieldbus, or encoder cards, while the built-in STO circuitry removes drive torque when a category 0 stop is required. The controller mates with power sections HCS02; HCS03; HCS04; HMS01; HMS02, allowing one control section type to support different current ratings across a machine family.
