(OC) Drive over
current

The output current
of drive during
operation exceeds
220% of drive’s
rated current.
●The output
terminals of drive
are short.
●The load is too
heavy.
●The acceleration
time is too short.
●Drive is
immediately
restarted after
coast to stop.
●Check wires of
U/T1,V/T2,W/T3
terminals to verify if
there is short
between terminals.
●Check the motor
and drive
compatibility.
●Check if the motor
operated in
over-rated
condition.
(GF) Grounding fault
●The three-phase
output current is
unbalance and
exceeding the
detection level of
grounding fault.
●Grounding fault
protection: F_098
The output terminal
of the drive is short
or grounding.
Check the insulation
value of motor and
the shield of motor’s
wire.
(OE) Over voltage
●The internal DC
bus voltage of
drive is over the
protection level.
●100V / 200V
series: About
DC410V.
●400V series:
About DC820V.
The deceleration
time of motor is too
short causing the
regeneration
voltage on DC bus
too high.
Increase the
―deceleration time‖ or
use high torque
braking and dynamic
brake unit to reduce
input voltage.
Power voltage is too
high.
Check if the power
input is within drive’s
rated input range.
(OH) Drive overheating
The temperature of
drive’s heat sink
reaches the 105
.
●The surrounding
temperature is too
high.
●The heat sink has
foreign body.
●The cooling fan of
drive is fault.
●Improve the system
ventilation.
●Clean the foreign
body on the heat
sink.
●Return the drive to
replace the cooling
fan.

Display Description Cause Troubleshooting
(OL) Motor overload
Operation current
exceeds 150% of
motor’s rated
current and
reaches the motor
overload protection
time.
●Motor is
overloaded.
●The voltage setting
of V/F pattern is
too high or too low.
●The current setting
of motor’s rated
current is invalid.
●Check the load of
motor.
●Check if the
acceleration or
deceleration time is
too short.
●Check if V/F setting
is proper.
●Check if the rated
current setting is
valid.
(OL1) Drive overload
Operation current
exceeds 150%
(120% for P type)
of drive’s rated
current and
continues for 1
minute.
●Motor overload.
●The voltage setting
of V/F pattern is
too high or too low.
●Drive capacity is
too small.
●Check the load of
motor if overload.
●Check if the
acceleration or
deceleration time is
too short.
●Check if V/F setting
is proper.
●Select the higher
capacity of drive.
(OLO) System overload
●Load system is
overload and the
operation current
reaches the
active level.
●Detection level:
F_068.
●Detection time:
F_069.
--- Check the usage of
mechanical
equipment.
(thr) External fault The multi-function
terminal receives
the external fault
signal.
Clear the external
fault and then press
key.
(PAdF) Keypad
interruption
during copy
●The connecting
wire of the keypad
is loosen.
●The keypad jack of
the drive is
oxidized.
Check the connecting
wire of keypad
