6 IOC Trip
Instantaneous
overcurrent trip
0
Short circuit was detected on
power-up
•Remove the short from the
power wiring
•Check for shorted motor
•Consult factory.
1
Short circuit was detected
during operation
7 MOL
MOL contact
fault
0
The MOL digital input was
activated, depending on pull-up
or pull-down logic
configuration
Reset MOL contact or
remove condition
causing the MOL
contact activation.
8 Model ID
ID # out of
range
0,1,2
Control board is not reading the
drive ID properly
Consult factory for
repair or replacement.
10 Res Lockout Restart lockout 0
The number of fault restarts is
greater than the limit defined in
the customer parameter.
Check the actual fault
in the fault log and use
the appropriate
remedy.
11 Ground Ground fault 0
The drive has detected current
imbalance between output
phases. Imbalance determined
to be current flow to ground.
•Check for unbalanced
currents.
•Check for grounded motor
leads or motor.
•Consult factory.
12 Vac Imblnce
Input voltage
imbalance
0
The drive has detected a single-
phase 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 OverVoltage
Overvoltage
condition
0
•The drive has detected an
overvoltage condition during
power-up
(not auto-resettable).
Verify incoming line
power is within
specification. Add
reactor or transformer
to correct.
1,3
•The drive has detected an
overvoltage condition during a
running condition.
Verify incoming line
power and check for
regenerative load.
Reduce Regen load or
add dynamic braking
resistors. Regen
Current Limit may
help; consult factory.
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 transformer
to correct.
15 Dyn Brake
Dynamic brake
overload
0
•The DB circuit is active on power-
up (not auto-resettable)
Check for failed
braking transistor.
Consult factory.
1
•The DB circuit is being activated
for too long, possibly causing the
resistor to overheat or fail.
Reduce braking cycle
or increase capacity.
Activate current limit;
consult factory.
2
•The DB circuit is overloaded
because of too large a
regenerative load.
Reduce braking cycle
or increase capacity.
Activate current limit;
consult factory.
3,4,5
•The DB circuit is faulty on power-
up (not auto-resettable).
18 OverCurrent
Overcurrent
condition
0
•The drive sensed an overcurrent
condition on power-up (not auto-
resettable).
Check for failed output
power device or
shorted motor.
1
•The drive sensed an overcurrent
condition during operation. The
current has exceeded the safe
operation point of power devices.
Reduce load on motor.
Verify that Motor FLA is
programmed correctly.
Check for mechanical
binding and shock
loading.
