voltage
Declared if attempting
to close the bypass

drive has earth fault
declared
If motor power(%) level
falls below minimum
power level establish in
parameter 30.03 for the
time (s) set in
parameter 30.02 fault
will be generated.
Parameter 30.03 is a
percentage of motor
power as defined in the
drive via parameter
99.09. Fault only

contactor is closed by
supervisory control 16
times within a 1 hour
period.

485 link between drive
and bypass stops

3024 will be generated.
If 3023 or 3024 is
generated, replace
respective contactor
If 3023 or 3024 is not
generated on power up,
replace RBCU unit.
Refer to the ACH550
manual
Check load
Reset bypass keypad
Check ACH550 manual,
fault code 17, for further
action
Check parameters
32.02-32.05. Increase
time delays on
parameters 32.04 and
32.05
Proper seating of cable
in drive and
RBCU(connector J3)
Check drive parameter
98.02 and 99.02
Check drive Group 53
