Fault Name In
Panel
UNDERVOLTAGE Fault will be generated
only if the drive is
controlling the motor
and the power to the
bypass is removed
before the drive shuts
down. This fault is
generated when the
drive contactor opens
while the drive is
operating.
DRIVE AI2 LOSS Only displayed when in
Supervisory mode.
Indicates that AI2 on
the drive has failed.
MTR OVERLOAD Bypass opens on
motor overload
conditions defined in
the drive
INP PHASE A Fault will be generated
LOSS when the bypass
contactor is requested
to be closed and the
RBCU does not sense
voltage on Phase A
INP PHASE B Fault will be generated
LOSS when the bypass
contactor is requested
to be closed and the
RBCU does not sense
voltage on Phase B
Fault Possible Cause
Loose J7 connector on
RBCU unit (refer to
page 91 for the J7
connector location)
Loose input wiring
Incoming power
problems
Check connections on
drive
Drive Mode:
Bad Motor
Bad CTs
Bad RBCU
Bypass mode:
Bad motor
Bad CTs
Bad RBCU
Either mode:
low input voltage
Loose J7 connector
(refer to page
the J7 connector
location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Loose J7 connector
(refer to page
the J7 connector
location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Corrective Action
Check that J7
connector is firmly
seated in RBCU (refer
to page 91 for the J7
connector location)
Check tightness of
incoming connections
Check Parameter 0413
to view voltage level at
time of trip
Check upstream
protection
Check connections on
drive
Check if overload
condition exists
Drive Mode:
Refer to ACH580
manual for proper
troubleshooting
techniques
Bypass Mode:
Check that J2
connector is firmly
seated in RBCU (refer
to page 91 for the J7
connector location)
Use clam
p meter to verify mtr
current vs. display in
parameter 0101
Check input voltage
Check J7 connector
91 for (refer to page 91
the J7 connector
location)
Check yellow wire on
input block
Check incoming
voltage, phase to
ground
Check J7 connector
91 for (refer to page 91
the J7 connector
location)
Check black wire on
input block
Check incoming
voltage, phase to
ground
