334 Fault tracing
A6E5 AI parametrization The current/voltage
hardware setting of an
analog input does not
correspond to parameter
settings.
Check the event log for an auxiliary
code. The code identifies the analog
input whose settings are in conflict.
Adjust parameter
12.15
/
12.25
.
Note: Control board reboot (either by
cycling the power or through
parameter
96.08 Control board boot
)
is required to validate any changes in
the hardware settings.
A6E6 ULC configuration User load curve
configuration error.
Check the auxiliary code. See actions
for
each code below.
0000 Speed points inconsistent. Check that each speed point
(parameters
37.11
…
37.15
) has a higher
value than the previous point.
0001 Frequency points
inconsistent.
Check that each frequency point
(
37.16
…
37.20
) has a higher value than
the previous point.
0002 Underload point above
overload point.
Check that each overload point
(
37.31
…
37.35
) has a higher value than
the corresponding underload point
(
37.21
…
37.25
).
0003 Overload point below
underload point.
A783 Motor overload Motor current is too high. Check the motor, and the machinery
coupled to motor, for overload.
Adjust the parameters used for the
motor
overload function (
35.51
…
35.53
) and
35.55 … 35.56 .
A784 Motor disconnect All three output phases are
disconnected from motor.
Check if parameter 95.26 enables the
use of a motor disconnect switch. If
not, check the following:
• All switches between drive and
motor are closed.
• All cables between drive and motor
are connected and secured.
If no issue was detected and drive
output was actually connected to
motor, contact ABB.
A780 Motor stall
Programmable
warning:
31.24 Stall
function
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Check motor load and drive ratings.
Check fault function parameters.
A791 Brake resistor Brake resistor broken or not
connected.
Check that a brake resistor has been
connected.
Check the condition of the brake
resistor.
