Product Description:

Bosch Rexroth Indramat supplies the CSB01.1C-ET-ENS-NNN-L1-S-NN-FW within its CSB Drive Controllers series. The module serves as the command and communication core for a drive, converting encoder feedback, discrete I/O, and Ethernet traffic into deterministic motion instructions used across automated lines. Integrating these functions inside the drive cabinet allows machine builders to coordinate axes, monitor safety interlocks, and exchange status data with supervisory PLCs without extra standalone hardware. Such integration helps reduce wiring and improves diagnostic visibility in packaging, printing, and material-handling installations.

Control electronics are supplied from a 24 V line, and the board draws 18.2 W, a figure used for cabinet thermal calculations during continuous duty. Its analog inputs are digitized by a 12-bit A/D converter, giving 4096 discrete steps for process variables such as tension or speed trim. The integrated digital output channel is rated at 24 V / 0.5 A, so it can drive contactors or signal lamps directly from the controller. For position feedback devices, the D-Sub encoder socket delivers up to 500 mA at a stabilized supply of 11.6 V, supporting typical absolute or incremental transducers without an external power pack.

Machine-level networking is handled by two RJ-45 jacks. With 2 identical ports, the drive can be daisy-chained into line or ring topologies that follow the 100Base-TX Ethernet standard. A dedicated L1 acknowledge contact rated at 24 V / 1 A permits direct confirmation of emergency-stop relays, matching the Stop Category 0 requirement listed for the starting lockout circuit. High-speed reference pulses enter through the TTL input that accepts frequencies up to 400 kHz, providing a direct way to synchronize the drive with encoder emulation or pulse-train controllers. These interfaces let the controller connect to safety circuits, pulse references, and plant Ethernet on the same board.
