Command value input impossible via master communication

Was bedeutet E4005 ?

Command value input from the master communication interface (fieldbus) is not possible for the IndraDrive MPx02. In firmware version 04VRS, this warning is named "No data exchange possible via the field bus." The drive may continue running with the last valid command value. This warning can lead to an automatic restart if not handled by the control unit.

• Failure of master communication (e.g., double MDT failure or double MST failure) has been detected on the fieldbus.
• Parameter P-0-4088 (Master communication, configuration) is set to display a warning instead of initiating a drive error reaction on communication failure.
• Physical disconnection or damage to the fieldbus cable.
• Incorrect network configuration (e.g., node address, baud rate).
• Master controller communication fault.

1. 1

   Inspect the fieldbus cabling (e.g., SERCOS, CANopen, PROFIBUS) for secure connections, damage, or breaks between the master controller and the IndraDrive MPx02.

2. 2

   Verify the communication status of the master controller and all other nodes on the fieldbus network, checking for any active communication errors.

3. 3

   Check the setting of parameter P-0-4088 (Master communication, configuration) in the IndraDrive MPx02; if set to warning, consider if a more robust error reaction (e.g., drive halt) is appropriate for the application.

4. 4

   Ensure that the control unit (master) implements an error reaction to reset bits such as "Drive Halt", "drive enable", and "drive ON" (e.g., bits 13, 14, 15 in P-0-4077, Field bus: control word) in case of bus failure to prevent automatic restart.

5. 5

   Refer to troubleshooting for related errors F4009, F4001, or F4002 if indicated by more detailed diagnostics in the system.
