OL1
Motor Overloaded
Motor Overload Fault. VFD output exceeded the
motor overload level.
Alarm or fault defined by L06-08.
1. Ensure VFD is programmed
with proper motor full load
Amps (E02-01).
2. Reduce the load.
XX
OL2
VFD Overloaded
VFD Overload Fault. VFD output exceeded the
overload level.
1. Reduce the load.
2. Extend the acceleration time.
XX
OPR
Oper Disconnect
Keypad Disconnected. The keypad is removed
while the VFD is running, and the run command
was initiated via the keypad RUN key.
1. Secure the keypad.
2. Verify O02-06 setting.
XX
OS
Over Speed
Overspeed Fault. The motor has exceeded the
programmed detection level and time. This is
typically caused by an overshoot condition due to
an over-responsive ASR loop. If the VFD is
programmed to flux vector “torque control” mode,
and no load is present, an overspeed fault will
typically occur.
Alarm or fault defined by F01-23.
1. Check the Automatic Speed
Regulator settings, D04 sub
group.
2. Check setting of F01-24,
F01-25.
3. Verify proper encoder PPR
setting, F01-01.
XX
OT1
Overtorque Det 1
Overtorque Detection Level 1.
Defined by L06-02. Alarm or fault defined by L06-
01.
1. Check for proper programming
for L06-02 and L06-03.
XX
OT2
Overtorque Det 2
Overtorque Detection Level 2.
Defined by L06-05. Alarm or fault defined by L06-
04.
1. Check for proper programming
for L06-05 and L06-06.
XX
OV
DC Bus Overvolt
Overvoltage Fault. The main circuit direct
current voltage exceeded the overvoltage level.
1. Extend the deceleration time.
2. Check for proper DBU
operation.
3. Check the resistor.
4. Check the line voltage.
X
OV (flashing)
DC Bus Overvolt
Overvoltage Fault. Overvoltage occurs during
stop. Main circuit DC voltage rises above the
detection level while the VFD output is off.
1. Check the line voltage. X
PF
Input Phase Loss
Input Phase Loss Fault. VFD input power supply
has open phase.
1. Check the line voltage and
fuses.
2. Remove power.
3. Re-tighten the input terminal
screws.
X
PGO-1-S
PGO-1-H
PG Open Ch1
Pulse Generator Channel 1 Fault.
PGO-1-S, software detected fault.
PGO-1-H, hardware detected fault.
Alarm or fault defined by F01-21.
1. Check for proper direction of
encoder feedback.
2. See Section 6.2 on page 210.
XX
PGO-2-S
PGO-2-H
PG Open Ch2
Pulse Generator Channel 2 Fault.
PGO-2-S, software detected fault.
PGO-2-H, hardware detected fault.
Alarm or fault defined by F01-21.
1. Check for proper direction of
encoder feedback.
2. See Section 6.2 on page 210.
