Product Description:

The CDB01.1C-S3-ENS-ENS-ENS-NNN-L2-S-NN-FW is a drive controller option card produced by Bosch Rexroth Indramat as part of the CDB Control Units series. Installed in an IndraDrive modular rack, it forms the interface between motion firmware and power electronics, coordinating feedback channels, safety functions, and communication paths between the control section and the power stage. By combining command processing and diagnostic channels on one platform, the unit streamlines wiring in packaging machines, palletizers, and gantry systems where synchronized multi-axis motion is required. Its role within the rack is to keep control data, status reporting, and axis coordination available through a single module.

It supervises 2 axes with an internal current loop that refreshes every 125 µs, enabling tight torque regulation during rapid profile changes. The logic stage is powered from 24 V DC, and a separate encoder rail provides 11.6 V at 500 mA so feedback circuits stay active during brief supply dips. Command data travel over SERCOS III through a shielded RJ-45, 8-pin port, giving deterministic exchange with upper-level PLCs. One analog input accepts ±10 V references, and a normally open relay contact provides hardware-ready feedback. The front face carries the standard control panel for local status review and parameter entry.

Startup draws an inrush of 6 A limited to a 60 ms pulse, preventing supply sag when several drives power up together. During operation the card dissipates only 9 W, easing cabinet cooling calculations and reducing thermal load inside the enclosure. Drive disable relies on Safe Torque Off, which blocks gate signals within microseconds without opening the DC link. Two analog outputs return status signals for external monitoring equipment, giving a direct electrical view of operating conditions during machine operation.
