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
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
Verify the power supply voltage to all CCD slave units in the chain against their specified operating voltage.
- 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
Verify the integrity of the CCD bus termination resistors and their placement if applicable to the specific communication protocol.
