Product Description:

Bosch Rexroth Indramat's CDB01.1C-SE-EN2-EN2-NNN-MEM-S2-S-NN-FW is a plug-in control section from the CDB Control Units series intended for IndraDrive power modules. By hosting two independent drive channels, the board processes encoder feedback, fieldbus commands, and safety signals so that servo or spindle axes can be synchronized, positioned, or speed-regulated in industrial automation cells. Its role is to translate high-level motion commands into precise pulse-width-modulated gate signals while maintaining integrated Safe Motion monitoring for machinery that must meet functional safety requirements. This arrangement allows one compact control section to coordinate axis behavior while keeping command handling, feedback evaluation, and protective functions on the same platform.

The board communicates with the drive system over SERCOS II, a real-time interface that carries cyclic command and status words while allowing parameter changes during operation. Axis-side position feedback is accepted through multifunction encoder ports that support EnDat 2.1 / 1 Vpp / 5 V TTL, providing both absolute and incremental formats without extra adapters. Internal energy demand is low, with base logic circuits drawing only 9 W, while each EN2 daughter module adds 6 W when active. These modules sense the encoder supply and maintain a regulated rail of 5.0 VDC, supplying protected excitation to transducers and helping reduce voltage drop on long feedback cables. The combination of flexible feedback support and modest internal power demand helps the control section fit multi-axis systems where stable signal handling is required throughout rapid motion cycles.

Current available for each encoder connection peaks at 350 mA, so digital scales or multiturn encoders can be powered directly from the card. For applications requiring position simulation, the MEM output delivers a programmable 1 MHz square-wave signal for SSI or incremental emulation in master-slave coordination. Safe Motion functions are hard-wired, and the output stage can switch 24 VDC / 0.5 A for category-oriented stop circuits. When the control loops are integrated into a SERCOS ring, telegrams are exchanged at up to 16 MBaud, supporting deterministic motion in fast pick-and-place or tooling axes. An independent relay path also handles 24 VDC at 1 A, separating the safety path from the main output stage and supporting controlled machine stopping behavior.
