Product Description:

The CSB02.1B-ET-EC-PB-L3-NN-NN-AW is a compact drive controller manufactured by Bosch Rexroth Indramat and used in the CSB Drive Controllers series. In an automation cell, it coordinates servo axes by processing fieldbus telegrams, monitoring safety signals, and generating power-stage commands for the attached inverter section. By integrating communication ports and safety-rated inputs, the unit provides centralized motion supervision, parameter storage, and diagnostics for conveyors, pick-and-place stations, and other cyclic equipment that require synchronized speed or position control.

The controller offers two analog outputs and three analog inputs. Each outgoing channel is resolved at 24 mV/incr, while incoming voltages are digitized with 13-bit accuracy for closed-loop tasks. This allocation supports simultaneous position feedback scaling, analog setpoint generation, and temperature monitoring channels. There are 11 discrete inputs that accept 24 V logic, and the safe torque off pair conforms to IEC 61131 Type 2 for machinery shutdown. A single transistor driver can sink up to 500 mA when actuating relays or indicator lamps. Internal consumption stays at 17 W, and three optional slots allow additional interface or feedback boards without enlarging the footprint.

Field connectivity is arranged on dedicated sockets. Position feedback enters through a 15-pin female D-Sub connector, whereas network traffic is handled by an 8-pin RJ-45 port that complies with the 100Base-TX Ethernet layer for 100 Mbit/s peer links. For legacy installations, the integrated Profibus interface follows the EIA-RS485 physical standard, and its repeater circuitry operates from +5 V (±10%) with a current draw of 75 mA from the motherboard rail. This current budget permits cascading segments without overloading the host supply and maintains deterministic telegram timing across extended cable runs.
