Product Description:

The CDB01.1C-SE-EN1-EN1-ENS-EN2-S1-S-NN-FW module is manufactured by Bosch Rexroth Indramat and belongs to the CDB Control Units series. It mounts on the power section of an IndraDrive servo amplifier to provide the command and communication layer for the drive. Within an automation cell, the board coordinates drive functions, gathers encoder data, and transmits operating status to a higher-level PLC for precise multi-axis motion and integrated safety control. Its location on the amplifier also lets the control electronics exchange signals with the power stage without requiring a separate external interface board.

The unit supervises motion for 2 independent axes, and each axis exchanges cyclic setpoints across SERCOS II. This bus is carried over fiber-optic cables, which provide noise immunity and galvanic isolation between the controller and the drive cabinet. For analog reference tasks, every differential channel offers a resolution of 19.5 mV per increment, which supports fine voltage signaling to connected hardware. Discrete machine devices can also be driven directly because the sourcing capacity reaches 500 mA per output. The control section therefore supports both precise command signals and conventional I/O loads within the same enclosure.

The integrated safety block is energized by a stabilized supply of 24 VDC. Each safe input draws only 3 mA per input, which reduces the load placed on emergency-stop buttons, light curtains, and interlock switches. Rotor position for the first axis is decoded through a Resolver/HSF interface, while separate 5 VDC and 11.6 VDC rails power secondary encoders. Setup and service access are provided through a dedicated RS-232 port when the optical ring is offline. Safety acknowledgment lamps can be fed from the protected 0.5 A output, and all circuit wiring terminates on the D-Sub 9 female connector used by the module's Safety Technology I/O system.
