Goodrive30 Series VFD Fault tracking
-118-
Overcurrent
during constant
speed running
To-ground short circuit or
output phase loss occur.
Strong external
interference sources.
Overvoltage stall
protection is not enabled
circuited (to-ground short
circuit or line-to-line short
circuit) or the rotation is not
smooth.
Check the output wiring.
Check if there is strong
interference.
Check the setup of related
function codes.
Grid voltage is too low.
Overvoltage stall
protection is not enabled.
Check the grid input power.
Check the setup of related
function codes.
Grid voltage is too low.
Rated motor current is set
improperly.
Motor stalls or load jumps
violently.
Check the grid voltage.
Reset the rated motor
current.
Check the load and adjust
torque boost.
Acceleration is too fast.
The motor in rotating is
restarted.
Grid voltage is too low.
Load is too large.
Power is too small.
Increase acceleration time.
Avoid restart after stop.
Check the grid voltage.
Select the VFD with larger
power.
Select a proper motor.
Phase loss or violent
fluctuation occurred to R, S
and T input
Check the input power.
Check the installation
wiring.
Phase loss on
output side
Phase loss occurred to U, V,
W output (or the three phases
of motor is asymmetrical)
Check the output wiring.
Check the motor and
cable.
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.
SI external fault input terminal
acts.
Check the external device
input.
Baud rate is set
improperly.
Set proper baud rate.
Check the wiring of
