Fault code
Fault type
Possible cause
Solution
OC3
[6] Overcurrent
during constant
speed running
 Load transient or
excepetion occurred.
 To-ground short circuit or
output phase loss occur.
 There is strong external
interference.
larger power.
 Check whether the
load is short circuited
(to-ground short circuit
or line-to-line short
circuit) or the rotation
is not smooth.
 Check the output
wiring.
 Check whether there is
strong interference.
OV1
[7] Overvoltage
during acceleration
 Exception occurred to
input voltage.
 There is large energy
feedback.
 Check the input power.
 Check whether load
deceleration time is too
short, or the motor
starts during rotating.
 Install dynamic braking
units.
OV2
[8] Overvoltage
during deceleration
OV3
[9] Overvoltage
during constant
speed running
UV
[10] Bus
undervoltage
 Grid voltage is too low.
 Check grid input
power.
OL1
[11] Motor overload
 Grid voltage is too low.
 Rated motor current is
set improperly.
 Motor stall or load jumps
violently.
 Check grid voltage.
 Reset rated motor
current.
 Check the load and
adjust torque boost.
OL2
[12] VFD overload
 Acceleration is too fast.
 The motor in rotating is
restarted.
 Grid voltage is too low.
 Load is too large.
 The motor power is too
small.
 Increase acceleration
time.
 Avoid restart after
stop.
 Check grid voltage.
 Select the VFD with
larger power.
 Select a proper motor.
OH1
[15] Rectifier
module overheat
 Air duct is blocked or fan
is damaged.
 Ambient temperature is
too high.
 Long-time overload
running.
 Ventilate the air duct or
replace the fan.
 Lower the ambient
temperature.
OH2
[16] Inverter module
overheat
