3-20 Placing and Configuring the Drive
Parameter 385 [Lgx CommLossData] determines what the drive does with
data from the controller when communication is lost. It determines if the drive
resets the data to zero or holds the data in its last state.
Configure these parameters, using DriveExecutive Lite. Locate them in the
Fault/Alm Config group of the Utility file.
