Product Description:

The CSB02.1B-ET-EC-NN-NN-DA-NN-FW is a compact drive controller from Bosch Rexroth Indramat that belongs to the CSB Drive Controllers series. It serves as the central interface between motion axes and higher-level controls, combining power stage gating, multi-protocol communication, and feedback processing so that motors in automated assembly lines, packaging machines, or machine tools receive coordinated torque and velocity commands. This arrangement allows the controller to manage command exchange and feedback handling within a compact cabinet layout.

An analog input bandwidth of 1.3 kHz allows high-speed setpoint tracking, while the analog output section resolves feedback in 24 mV/incr steps for precise diagnostics. On the network side, the built-in Multi-Ethernet stack supports the physical layer specified as 100Base-TX and presents two shielded sockets in the RJ-45, 8-pin format for straightforward daisy-chain wiring. Feedback from resolvers, EnDat, or other devices is accepted through a Multi-Encoder interface, and real-time probe latching is possible through two dedicated probe inputs. The housing stands 241 mm tall, while its narrow width and modest depth help it fit a single slot in a standard control cabinet. Inrush suppression limits the charging surge to a pulse only 1 ms wide, which helps reduce stress during power-up.

The controller draws a startup current of less than 5 A and provides 2 Multi-Ethernet ports once energized. These ports can be extended by a Digital/Analog I/O module when additional field signals are required. Relay contacts on the front panel can switch loads up to 1000 mA at a maximum of 30 V, allowing direct control of brakes or contactors without an auxiliary relay. Internal circuitry tolerates short peak currents because the inrush limiter resets after the 1 ms interval. This helps the unit return to normal operation after the initial charging pulse has passed.
