Why am I getting internal faults on ATV320 when one speed pot is being used on 2 different ATV320 drives?

Issue:
Getting Internal Faults on ATV320 , when one speed pot is being used on 2 different ATV320 drives

Product Line:
ATV320

Environment:
Speed pot

Cause:
n/a

Resolution:
When using qty of 2- ATV320 drives and was using one speed pot, for both drives. The drives work ok normally, but when you stop one of the drives (and not the other one) - gives a Internal fault. Appears the +10v is being backfed into the other drive. If you stop them at the same time, then works ok.  One solution would be to provide a separate speed pot for each drive or stop them at the same time.
