ACH580 Ultra-Low Harmonic Drives Installation, Operation and Maintenance Manual
Fault Name In
Panel
INP PHASE C Fault will be generated
LOSS when the bypass
contactor is requested
to be closed and the
RBCU does not sense
voltage on Phase C
DRIVE 1ST START Fault generated if
attempting to close the
bypass contactor with
out running the bypass
in drive mode first.
COIL POW Coil power supply has
SUPPLY 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 Supervisory Mode
FAULT only. Declared if
bypass contactor is
closed by supervisory
control 16 times within
a 1 hour period.
DRIVE LINK Supervisory Mode
FAULT Only. Fault generated if
RS-485 link between
drive and bypass stops
communicating.
Fault Possible Cause
Loose J7 connector
(refer to page
the J7 connector
location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
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"
Corrective Action
Check J7 connector
91 for (refer to page 91
the J7 connector
location)
Check red on input
block
Check incoming
voltage, phase to
ground
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 50.
Check load
Reset bypass keypad
Check fault code A780
on page 55, 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
