Trips and Fault Finding
650 Series AC Drive
When more than one trip is to be represented at the same time then the trip codes are simply
added together to form the value displayed. Within each digit, values between 10 and 15 are
displayed as letters A to F
For example referring to the tables above, if the AUTO RESTART TRIGGERS parameter is set
to
04A0
,
then this represents:
a
“
4
” in digit 3
an “8” and a “2” in digit 2
(8+2 = 10, displayed as
A
)
an
“
0
” in digit 1
This in turn represents the trips BRAKE SWITCH, ANIN FAULT, MOTOR STALLED and
INVERSE TIME.
In the same way, the AUTO RESTART T parameter set to
04A0
would represent
OVERSPEED, ANIN FAULT, DESAT OVER I
and 10V FAULT
.
