Product Description:
The CSB02.1B-ET-EC-NN-L3-DA-NN-AW drive controller is produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. It operates as a central module that converts low-voltage control power into timed drive commands, allowing automated lines to synchronize axes, monitor feedback devices, and exchange status data with supervisory PLCs through its integrated Multi-Ethernet backbone. The device is mounted inside control enclosures where precise position, speed, and torque regulation are required for packaging, printing, or material-handling machinery. Its role is to coordinate control functions between the motion system, connected feedback devices, and the higher-level machine controller.
The controller runs from a DC 24 V logic supply and draws a steady 17 W of base power to support its internal processor, communication stack, and local I/O. The controller has 11 digital inputs for limit switches or sensor contacts. For analog inspection tasks, three voltage channels accept transducer signals, and a converter with 14-bit resolution captures measurement data with fine detail. Process data and diagnostics are transferred across an Ethernet PHY rated at 100Base-TX, permitting deterministic traffic on standard CAT-5e cabling. Two unipolar analog outputs and an RJ-45, 8-pin port complement these resources, and the internal backplane relays state changes to the power section without additional interface cards.
Machine safety is handled through the integrated Safe Torque Off function, which removes drive energy to connected motors without cutting control logic. Peripheral sensors can draw up to 500 mA from the standard field supply, while an auxiliary L3 rail provides 350 mA for encoder or brake release lines. The controller includes 3 optional slots for future expansion without changing the core control layout. Position feedback from resolvers, EnDat, or Hiperface is accepted by the Multi-Encoder interface, and relay outputs rated up to 30 V enable direct actuation of low-power contactors or indicator lamps.
