Product Description:

Bosch Rexroth Indramat’s CDB01.1C-SE-EN1-EN1-NNN-NNN-NN-S-NN-FW is a plug-in motion control card from the CDB Control Units series. Mounted inside a compatible drive, it supplies command processing and I/O routing for servo axes in industrial automation systems. Within a multi-axis platform, the card coordinates motor feedback, field communication, and peripheral signaling so that production machinery can perform synchronized positioning, speed regulation, and safety-related stop sequences. Its plug-in format keeps these control functions inside the drive rather than in a separate external module.

The board supervises 2 drive channels, allowing parallel closed-loop control of paired servo axes. For analog diagnostics or speed references, the buffered output rail reaches a full-scale level of 5 V, while its sourcing capability is limited to 1 mA to protect downstream circuitry. Each increment on that rail equals 19.5 mV/inc, allowing fine control when mapping process variables. Motion setpoints and status words are exchanged through the SERCOS II fiber network, which provides deterministic update cycles between the controller and higher-level PLCs.

Additional drive-side interactions are handled through transistor and relay channels. The digital outputs can sink or source up to 500 mA, enabling direct actuation of contactors or indicator lamps without intermediate amplifiers, while the onboard relay contact is rated for 1 A. Two resolver/HSF encoder ports are present, and each HSF channel has 10 kΩ of input resistance and uses an 8 V carrier. The resolver windings receive 18.2 Vpp at a 4 kHz excitation frequency to maintain position accuracy over long cables. This arrangement supports direct connection of standard feedback devices used on servo motors. At power-up, the card draws an inrush current of 6 A for roughly 60 ms before settling to a steady consumption of 9 W. The unit has no integrated safety technology, so emergency-stop logic must be provided externally.
