Product Description:

The CSB01.1C-PL-ENS-EN2-L2-S-NN-FW is a drive controller component manufactured by Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. As a single-axis control unit, it forms the command layer between a higher-level PLC and a power module, coordinating torque, speed, and position loops in industrial automation lines. By hosting encoder feedback and field I/O inside a compact housing, the device simplifies cabinet layouts and supports precise motion tasks such as pick-and-place, packaging, or material-handling stages.

Real-time commands arrive through a Parallel Interface, which delivers deterministic timing without additional fieldbus converters. Internal electronics are powered from a DC 24 V control supply, isolating logic from the main drive bus and allowing safe parameter retention during power events. The current loop refreshes every 125 µs, so torque demands can be updated eight thousand times per second, a rate suited for servo applications that require tight dynamic control. Primary feedback enters through the multifunction encoder port that accepts IndraDyn / Hiperface / 1 Vpp / TTL signals, giving flexibility when motors with different transducer formats are used. A standard control panel on the front offers direct parameter access. These functions are enclosed in a chassis measuring 241 × 49.5 × 103 mm, which helps save cabinet space.

The first encoder channel is energized with 12 V, while the second channel receives 5 V, so both incremental and absolute sensors can be wired without external regulators. A second feedback socket supports EnDat 2.1, 1 Vpp, or 5 V TTL formats for dual-loop control. For machine signals, the PL connector routes 16 DI / 16 DO through a 37-pin D-Sub, and a single N/O relay contact is available for status forwarding. Functional safety is handled by Safe Torque Off, activated through a 9-pin safety plug, and diagnostic access is available through an unbuffered RS-232 service port.
