Product Description:
The CSB02.1B-ET-EC-EC-L3-NN-NN-FW drive controller is produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. It operates as the control section in modular converters, interpreting encoder feedback, supervising safety circuits, and forwarding commands to the attached power module. In industrial automation, it coordinates the motion of servomotors and maintains deterministic exchange with higher-level PLCs, making it suitable for packaging machines, handling axes, and general-purpose assembly lines. Because it serves as the control section rather than the power stage, the unit focuses on command processing, feedback handling, and network coordination while the attached module supplies motor power.
The controller provides 2 analog outputs for speed or torque references. It also accepts 11 digital inputs that can trigger drive functions such as homing or quick stop. An additional 5 configurable digital I/O points can be set as inputs or outputs, allowing the device to match common sensor and actuator requirements without separate interface hardware. Data exchange with supervisory equipment is handled through Multi-Ethernet communication, so EtherNet/IP, PROFINET, and EtherCAT can be selected by software rather than hardware. Integrated functional safety is realized through STO (Safe Torque Off), which removes gate drive energy and lets the motor coast when a safety circuit is opened while meeting SIL1/PL c requirements.
Three optional slots let the controller accept encoder converters or additional fieldbus cards while keeping the main dimensions unchanged. The internal encoder supply delivers 500 mA at 12 V, and a second rail provides 500 mA at 5 V, supporting SSI, TTL, or Hiperface sensors. The logic section can also source 350 mA L3 drive output for auxiliary loads such as braking relays. High-resolution measurement is maintained by 13-bit voltage resolution on connector X35, which improves signal monitoring and supports more precise diagnostics during operation.
