Troubleshooting
133
Name
Description
Possible Causes & Corrective Action
Contactor Flt
[F03]
The command to close the contactor
and the contactor feedback do not
match before the time specified by the
Contact Flt Time parameter
.
Check Parameter Settings and Contactor
Check CONTACT FLT TIME
(A1)
parameter for the correct contactor fault
time
.
Check wiring to logic input configured as
CONTACT CFIRM
Contactor hardware problem
Run Command / Contact Confirm Timing
Check Contact Cfirm logic input vs. Run
command
Increase CONTACT FLT TIME (A1)
enough for both CONTACT CFIRM and
RUN to be active
If nuisance fault, the fault can be disabled by
CONT CONFIRM SRC (C1) parameter (set
to none).
Cube ID Fault
[F05]
The identification number for the drive
is invalid.
Hardware Problem
Power cycle the drive.
If re-occurs, replace Drive Control board
If re-occurs, the drive needs to be
replaced
Curr Reg Flt
[F06]
Actual current does not match the
command current. The drive is
commanding more motor voltage then
is available on the input.
Current Regulation problem
Verify that SW1 (Safe-Off) position is set
to I9 (right) position if not using Safe-Off.
Refer to SAFE-OFF on page 159.
Verify that if SW1 (Safe-Off) is set to BE
(left) position to enable the SAFE-OFF,
logic input 9 should be triggered on
when drive is told to RUN. Refer to
SAFE-OFF on page 159.
Check for a low input line
Check if drive accurately reading the dc
bus
Measure the dc bus with a meter
across terminals B1 and
–
Compare that with the value on the
digital operator, DC BUS VOLTAGE
(D2)
Complete Adaptive Tune and Inertia
procedure,
Check for a possible motor open phase
Check if contactor is closing.
Check for accurate motor parameters
(A5)
Verify motor nameplate values are
entered correctly
Complete Adaptive Tune and Inertia
procedure,
As a last step, calculate motor
parameters from motor’s equivalent
circuit
.
Otherwise, replace the drive
