OH3
Motor Overheat 1
Motor Overheating 1. Thermistor
analog input detected motor
overheating. See L01-03. Alarm
defined by L01-03.
1. Check the motor rated current
value, E02-01.
2. Increase cycle time or reduce the
load.

OH4
Motor Overheat 2
Motor Overheating 2. Thermistor
analog input detected motor
overheating. See L01-04
X
OL1
Motor Overloaded
Motor Overload Fault. Inverter
output exceeded the motor overload
level.
Alarm or fault defined by L06-08.
1. Ensure drive is programmed with
proper motor full load Amps
(E02-01).
2. Reduce the load.
X X
OL2
Drive Overloaded
Inverter Overload Fault. Inverter
output exceeded the inverter
overload level.
1. Reduce the load.
2. Extend the acceleration time. X X
OPR
Oper Disconnect
Keypad Disconnected. The keypad
is removed while the inverter is
running, and the run command was
initiated via the keypad RUN key.
1. Secure the keypad.
2. Verify O02-06 setting. X X
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 drive 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.
X X
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.
X X
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.
X X
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 drive output is off.
1. Check the line voltage. X
PF
Input Phase Loss
Input Phase Loss Fault. Inverter
input power supply has open phase.
1. Check the line voltage and fuses.
2. Remove power.
3. Re-tighten the input terminal
screws.

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. Please reference troubleshooting
encoder related faults on page 6-
16.
X X
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.
