CCD slave error

Bosch Rexroth · IndraDrive MPx02

What does F2140 mean?

A communication error has occurred with a CCD (Cascaded Communication Device) slave unit. CCD is a communication protocol used for connecting multiple devices in a daisy-chain or cascaded fashion. This fault signifies that one of the slave devices is not communicating properly, which can disrupt control of the entire chain.

Common Causes

  • Communication line break or short circuit to a CCD slave
  • Defective CCD slave device
  • Incorrect addressing of a CCD slave
  • Power supply issue to a CCD slave
  • EMC interference affecting CCD communication

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Inspect all CCD communication cables and connectors for the entire daisy-chain for physical damage, proper seating, and secure connections at all slave devices and the IndraDrive master.

  2. 2

    Verify the power supply voltage to all CCD slave units in the chain against their specified operating voltage.

  3. 3

    Check the communication parameters (e.g., slave addresses, baud rates, bus termination settings) in the IndraDrive MPx02 and on all CCD slave devices for correct configuration according to the system documentation.

  4. 4

    Verify the integrity of the CCD bus termination resistors and their placement if applicable to the specific communication protocol.
