12
Vac Im-
blnce
Input voltage im-
balance
0
The drive has detected a
singlephase condition or a
voltage imbalance outside
the drive’s rating while
running a load that could
be damaging to the drive.
Check input voltage and current for
imbalance, and correct.
13
OverVolt-
age
Overvoltage con-
dition
0
The drive has detected an
overvoltage condition dur-
ing power-up (not auto-re-
settable).
Verify incoming line power is within
specification. Add reactor or trans-
former to correct.
1, 3
The drive has detected an
overvoltage condition dur-
ing a running condition.
Verify incoming line power and
check for regenerative load. Re-
duce Regen load or add dynamic
braking resistors. Regen Current
Limit may help; consult VACON.
2
The drive has detected an
overvoltage condition on
power-up on the load side.
Verify incoming line power is within
specification. Add reactor or trans-
former to correct.
15
Dyn Brake
Dynamic brake
overload
0
The DB circuit is active on
power-up (not auto-reset-
table)
Check for failed braking transistor.
Consult VACON.
1
The DB circuit is being ac-
tivated for too long, possi-
bly causing the resistor to
overheat or fail.
Reduce braking cycle or increase
capacity. Activate current limit;
consult VACON.
2
The DB circuit is overload-
ed because of too large a
regenerative load.
Reduce braking cycle or increase
capacity. Activate current limit;
consult VACON.
3, 4, 5
The DB circuit is faulty on
power-up (not auto-reset-
table).
18
OverCur-
rent
Overcurrent con-
dition
0
The drive sensed an over-
current condition on pow-
erup (not auto-resettable).
Check for failed output power de-
vice or shorted motor.
1
The drive sensed an over-
current condition during
operation. The current has
exceeded the safe opera-
tion point of power devices.
Reduce load on motor. Verify that
Motor FLA is programmed correct-
ly. Check for mechanical binding
and shock loading.
19
Over
Temp
Over-tempera-
ture condition
0
The temperature of the
heatsink exceeded a tem-
perature limit.
Check that ambient temperature
does not exceed drive’s rating.
Check for fan operation (assuming
drive has fans installed).
1
The temperature of the
control board exceeded a
temperature limit.
Check that ambient temperature
does not exceed drive’s rating.
Check for fan operation (assuming
drive has fans installed).
2
The drive sensed the heat-
sink thermistor sensor is
faulty or not connected
properly.
Check thermistor connections or
replace. Consult VACON.
3
The drive sensed the con-
trol board thermistor sen-
sor is faulty or not
connected properly.
Check thermistor connections or
replace. Consult VACON.
20
Motor TOL
Motor timed
overload trip
0
The drive detected an over-
load that exceeds the cus-
tomer’s defined overload
setting.
Check load current demand. Verify
Motor FLA is programmed to the
correct value. Verify TOL charac-
teristic is correct for the applica-
tion.
21
Low Temp Low temperature
0
This fault occurs if the
temperature of the heat-
sink falls below –10.0 de-
grees C.
Verify that ambient temperature is
within the drive’s specifications; in-
crease the ambient temperature if
necessary.
