Product Description:
The CDB01.1C-PB-EN2-EN2-NNN-NNN-NN-S-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. As a plug-in control section for IndraDrive power modules, it manages motion commands, fieldbus traffic, and feedback processing for servo axes in automated machinery. Two integrated encoder channels accept EnDat 2.1, 1 Vpp, or 5 V TTL signals so that the drive controller can close precise position and velocity loops without external interface cards.
The unit communicates with higher-level PLCs through the PROFIBUS-DP protocol, allowing deterministic exchange of command words and diagnostic data. Analog monitoring points are delivered at a resolution of 19.5 mV/inc, giving fine-grained voltage feedback to supervisory systems. Internal logic circuits draw a base power of only 9 W, which minimizes cabinet heat rise. Each digital output channel can source up to 500 mA, enabling direct actuation of status lamps or small relays without additional driver boards. All logic and sensor circuitry is powered from a control supply of 24 V DC; the board regulates this rail for its microprocessors, optocouplers, and encoder supplies while maintaining isolation from mains potential.
A startup surge of 6 A occurs when the controller is first energized, and this inrush lasts approximately 60 ms, so upstream power supplies should be sized to tolerate that transient. When operating on PROFIBUS, telegrams are exchanged at up to 12 MBaud, and the recommended shielded trunk length reaches 75 m when sense lines are used to compensate voltage drop. The D-Sub 9-pin female connector simplifies daisy-chain installation, and the relay output is rated for 24 V DC at 1 A to drive interlock coils. Additional 5 V encoder power and 1.1 A I/O current are provided on dedicated terminals so sensors and feedback devices can be supplied directly from the card.
