oH
Heatsink Overheat
The heatsink temperature exceeded the overheat pre-alarm
level set to L8-02. The default value for L8-02 is
determined by drive capacity (o2-04).
oH1
Heatsink Overheat
The heatsink temperature exceeded the drive overheat
level. Overheat level is determined by drive capacity
(o2-04).
oH3
Motor Overheat Alarm (PTC input)
• The motor overheat signal to analog input terminals A1
or A2 exceeded the fault detection level.
• Detection requires setting multi-function analog inputs
H3-02 or H3-10 to E.
oH4
Motor Overheat Fault (PTC input)
• The motor overheat signal to analog input terminals A1
or A2 exceeded the fault detection level.
• Detection requires setting multi-function analog inputs
H3-02 or H3-10 to E.
oL1
Motor Overload
The electronic motor overload protection tripped
oL2
Drive Overload
The thermal sensor of the drive triggered overload
protection.
oL3
Overtorque Detection 1
The current has exceeded the value set for Torque
Detection Level 1 (L6-02) for longer than the allowable
time (L6-03).
oL7
High Slip Braking oL
The output frequency stayed constant for longer than the
time set to n3-04 during High Slip Braking.
oPr
HOA Keypad Connection Fault
The HOA keypad has been disconnected from the drive.
An oPr fault will occur when all of the following conditions
are true:
• Output is interrupted when the keypad is disconnected
(o2-06 = 1).
• The Run command is assigned to the keypad (b1-02 = 0
and OFF mode has been selected).
• Drive software versions PRG: 1014 and later detect an
oPr fault when the HOA keypad is removed from the
drive while the sequence timer is active, even when oPr
error detection is disabled (o2-06 = 0).

ov
Overvoltage
Voltage in the DC Bus has exceeded the overvoltage
detection level.
• For 200 V class drives: approximately 410 V
• For 400 V class drives: approximately 820 V (740 V
when E1-01 is less than 400)
ov2
Overvoltage 2
Bus voltage is boosted because the motor cable is too long.
PF
Input Phase Loss
Drive input power has an open phase or has a large
imbalance of voltage between phases. Detected when
L8-05 is set 1 (enabled).
SEr
Too Many Speed Search Restarts
The number of Speed Search restarts exceeded the value
set to b3-19.
STo
Motor Pull Out or Step Out Detection
Motor pull out or step out has occurred. Motor has
exceeded its pull-out torque.
TdE Time Data Error
TIM Time Not Set
UL3
Undertorque Detection 1
The current has fallen below the minimum value set for
torque detection (L6-02) for longer than the allowable time
(L6-03).
UL6
Motor Underload
The weight of the load has fallen below the underload curve
defined in L6-14.
Uv1
DC Bus Undervoltage
Voltage in the DC bus fell below the undervoltage
detection level (L2-05).
• For 200 V class drives: approximately 190 V
• For 400 V class drives: approximately 440 when using
input voltages 460 V or higher (350 V when E1-01 is
less than 400, and 380 V when 400V ≤ E1-01 < 460
V )
The fault is output only if L2-01 is set to 0 or 1 and the DC
bus voltage has fallen below the level set to L2-05 for
longer than the time set to L2-02.
Uv2
Control Power Supply Undervoltage
Voltage is too low for the control drive input power.
Uv3
Soft Charge Circuit Fault
The soft-charge bypass circuit failed.
voF
Output Voltage Detection Fault
Problem detected with the voltage on the output side of the
drive.
<1> Displayed as CPF00 when occurring at drive power up. When one of the faults occurs after successfully starting the drive, the display will show
CPF01.
<2> Displayed as CPF20 when occurring at drive power up. When one of the faults occurs after successfully starting the drive, the display will show
CPF21.
