Setting Fieldbus Connection Timeout Preferences
The VFD interface allows the user to set the Communication Loss Timeout and Communication Loss
Action values. These parameters are at addresses P5-05 and P5-06 respectively. The Timeout units
are 1 = 0.1 sec and the range is from 0.0 (disable) to 5.0 seconds. Set these appropriately. A setting of
0.0 seconds will allow the VFD to continue running if communications is lost.
