determined by the following
formula: Fref = Fref at time of
loss * L4-06.

Sets the counter for the number
of times the Drive will perform
an automatic restart on the
following faults: GF, LF, OC,
OV, PF, PUF, RH, RR, OL1,
OL2, OL3, OL4, UV1. Auto
restart will check to see if the
fault has cleared every 5ms.
When no fault is present, the
Drive will attempt an auto
restart. If the Drive faults after
an auto restart attempt, the
counter is incremented. When
the Drive operates without fault
for 10 minutes, the counter will
reset to the value set in L5-01.
