Product Description:

The CDB01.1C-SE-ENS-ENS-NNN-MEM-S2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. It serves as the processing core for compact inverter combinations, providing command and feedback management for industrial automation where precise multi-axis positioning is required. The unit acts as the interface between higher-level control commands, drive functions, and connected feedback devices during coordinated motion. By integrating motion processing, real-time fieldbus, and safety logic on one board, it saves cabinet space while consolidating drive control functions.

Its motion channel capacity is 2 axes, each supervised through SERCOS cyclic communication. Parameter access is available on a single-line control panel that shows status and diagnostics without an external HMI, so operating information can be reviewed directly at the unit. Two identical ENS encoder channels accept differential incremental and SSI absolute feedback through a D-Sub 15 female connector and supply the transducers with 12 V power. For legacy position controllers, the card reproduces quadrature or SSI signals up to 1 MHz, allowing high-resolution emulation of motor movement. Mechanical depth is 103 mm, so the module fits standard Rexroth drive bays without exceeding enclosure clearances.

System power is fed by a 24 V rail, which covers I/O logic and the Safe Motion circuitry, and is routed through a D-Sub 9 female safety connector. Safety inputs draw 3 mA on that supply, while safety semiconductor outputs can source 0.5 A for external relays or contactors. The front width is 49.5 mm and the overall height is 322.6 mm, which supports dense mounting in compact drive assemblies. An integrated Safe Motion stack monitors velocity and position and trips the axes if thresholds are violated, eliminating the need for discrete relays. This arrangement keeps motion control and safety functions in the same control section without requiring additional standalone safety hardware.
