Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-MEM-S2-S-NN-FW is a modular drive control card manufactured by Bosch Rexroth Indramat for integration into the CDB Control Units series. Acting as the intelligence layer in an IndraDrive stack, it links servo power stages with factory networks, processes position feedback, and supervises built-in safety circuits so a machine axis can be commanded, monitored, and shut down according to automation requirements. It also processes position feedback through two integrated encoder evaluators that pass data directly to the control loop.

Its electrical budget is limited to 9 W of base consumption, which eases cabinet thermal management. When power is first applied, the card can draw a surge of 6 A, so upstream breakers must accommodate the short inrush period. For fieldbus traffic, the board presents a single RJ-45, 8-pin port that follows the 100Base-TX standard, and the stackable design is classified as Multi-Ethernet for selectable industrial Ethernet protocols. The analog output channel steps at 19.5 mV/inc, giving fine voltage resolution for speed or torque references. Feedback enters through a D-Sub 15 female connector, and an internal 12 V rail supports the encoder evaluation circuitry.

Safety and status signaling are handled separately from the process I/O. The ready relay can switch up to 24 VDC, 1 A, giving a hardwired indication that the drive is prepared for motion. Functional safety uses the Safe Motion concept; dedicated terminals on a D-Sub 9-pin female connector carry a permissive input of 3 mA and a downstream enable output limited to 0.5 A. For controller handoff, the board supplies 1 mA on its analog current channel, and position words are mirrored through the Absolute SSI emulation memory module. These signals let the axis transition between operating and safe states under hardware control.
