Fault Name In
Panel
DRIVE 1ST START Fault generated if
attempting to close the
bypass contactor with
out running the bypass
in drive mode first.
COIL POW SUPPLY Coil power supply has
failed to reach rated
voltage
EARTH FAULT Declared if attempting to
close the bypass
contactor when the drive
has earth fault declared
MTR UNDERLOAD If motor power(%) level
falls below minimum
power level establish in
parameter 3003 for the
time (s) set in parameter
3002 fault will be
generated. Parameter
3003 is a percentage of
motor power as defined
in the drive via
parameter 9909. Fault
only applies to bypass
mode
MAX CYCLE FAULT Supervisory Mode only.
Declared if bypass
contactor is closed by
supervisory control 16
times within a 1 hour
period.
DRIVE LINK FAULT Supervisory Mode Only.
Fault generated if RS-
485 link between drive
and bypass stops
communicating.
PHASE SEQ Sequence of 3 phase
voltage input is such that
bypass operation will
result in motor rotation
opposite of drive forward
operation.
Fault Possible Cause
NA
Internal failure on RBCU
unit
Shorted contactor coil
Earth fault in motor
Broken belt
High and low levels of
hysteresis band are too
tight
Bad cable/connection
between drive and
bypass.
Drive parameter 95.21,
bit 5 not set for
"Bypass present"
Phase sequence
unknown at time of
wiring
125
Corrective Action
Run bypass unit in drive
mode before attempting
bypass mode
Cycle power on bypass
unit. If contactor coil is
shorted, fault 3023 or
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 fault code
A2B3 on page 57.
Check load
Reset bypass keypad
Check fault code A780
on page 62, for further
action
Check parameters
3202-3205. Increase
time delays on
parameters 3204 and
3205
Proper seating of cable
in drive and RBCU
(connector J3)
Check that drive
parameter 95.21, bit 5 =
"Bypass present"
Check drive Group 58
Follow DriveLink
recovery procedure
Swap any two of the
three input wires to the
bypass unit
