To avoid the ground fault F13, the parameter A109 needs to be adjusted in addition to

using a specified ferrite core. This feature is available with the custom firmware above

version 51.02.

A109 [Ground Fault Avoid]

In some cases, the ground fault F13 occurs, especially when two motors are

connected to one PowerFlex4 drive and the one motor is connected / disconnected

by switching on / off a contactor, while the other motor is running.

To avoid the F13 fault, all three motor leads shall be wrapped through a specified

ferrite core (TDK ZCAT3035-1330 or 1321-M001). Additionally, parameter A109

can be used to select the F13 fault-monitoring mode.
