3013 DRIVE 1ST START Fault generated if
attempting to close the
bypass contactor with
out running the bypass
in drive mode first.
NA Run bypass unit in
drive mode before
attempting bypass
mode
3014 COIL POW
SUPPLY
Coil power supply has
failed to reach rated
voltage
Internal failure on
RBCU unit
Shorted contactor coil
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.
3016 EARTH FAULT Declared if attempting
to close the bypass
contactor when the
drive has earth fault
declared
Earth fault in motor Refer to the fault code
16 on page 25.
3017 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
