Product Description:

The CDB01.1C-SE-ENS-ENS-EN2-EN2-NN-S-NN-FW is a dual-axis control section produced by Bosch Rexroth Indramat for the CDB Control Units series. When inserted into an IndraDrive amplifier, it supervises positioning, velocity, and diagnostic tasks for two motors while exchanging deterministic data with the machine PLC. By converting motion commands into conditioned current references and evaluating encoder feedback, the board serves as the intermediary between higher-level automation and the drive's power electronics in production lines, material-handling cells, and packaging equipment. This arrangement lets one control section coordinate synchronized motion on paired drive channels without requiring a separate control board for each motor.

For reference generation, the board offers 2 analog outputs; each channel can deliver 1 mA at a nominal 5 V. It independently regulates 2 axes, yet draws only 9 W of base power, which helps limit heat buildup inside compact cabinets. Command and status words travel on the fiber-optic SERCOS II bus, and discrete states are captured through 22 digital inputs. These inputs switch LOW below the 5 V off threshold and HIGH above the 15 V on level, allowing direct connection of standard 24 V sensors. Two ENS slots plus two EN2 slots accept feedback modules, so incremental, absolute, or redundant encoders can be monitored without external interface cards.

On the output side, a transistor driver supplies up to 500 mA for brake magnets or contactors. The secondary encoder rail operates at 5.0 V and 350 mA, while the primary ENS rail provides 11.6 V and 500 mA for high-resolution sensors. Fast registration moves are enabled by a capture circuit that latches position on probe pulses as short as 4 µs, supporting accurate tracking when products or tooling move quickly past a registration point. Separate supply rails for the encoder connections help the board support different feedback devices within the same drive assembly. This layout keeps control functions, sensor power, and signal capture inside the amplifier rather than relying on auxiliary interface hardware.
