Option External Fault

Hva betyr EF0 ?

This fault occurs when the drive loses communication, and parameter F6-03 is configured to stop the drive. Specifically, if the time between messages exceeds the Cable Loss Timeout (AO 21) interval, the drive declares EF0 and sets the speed command (AO 1) to 0, stopping according to F6-03 settings.

• Time between communication messages exceeded Cable Loss Timeout (AO 21)
• Communication Fault Enable (BO 11) is 'On'
• Parameter F6-03 is set to 0, 1, or 2, determining the stopping method

1. 1

   Verify the communication line integrity and master device operation.

2. 2

   Check parameter AO 21 (Cable Loss Timeout) for appropriate interval setting.

3. 3

   Verify parameter BO 11 (Communication Fault Enable) is set to 'On' if this fault behavior is desired.

4. 4

   Check parameter F6-03 to understand the stopping method (0=Ramp, 1=Coast, 2=Emergency Stop).
