8.6.6 Inverter unit overheating
The inverter unit is
overheating.
Clean the heat sink to
improve the cooling
conditions
Reduce the carrier
frequency
If it is an inverter unit
fault, contact our
company
If it is an inverter unit
fault, contact our
company
Reduce the load and
increase the capacity
of the inverter
Add a cooling device
or derate the inverter
Whether the ambient
temperature is too
high?
Whether the carrier
frequency is too high?
Whether the heat sink
is blocked?
Whether the fan of
the inverter emits an
unusual sound?

Whether the load is too
heavy or the capacity of
the inverter is too small?
8.6.7 Motor stalls during ACC
Motor stalls during
ACC
Whether the ACC
time is too short?
If it is an inverter fault or
interference, contact our
company
Overcurrent
If it is an inverter fault
or interference,
contact our company
Whether parameter
autotuning is
performed
Modify the torque
boost
Whether the
torque boost
is too high?
过电流
Whether a special
motor is used?
Reduce the inertia of
the load and
increase the capacity
of the inverter
Whether it is V/F
control?
Contact our
company
Whether the load
torque is too large?
Use larger cables, shorten the
wiring distance, adjust the voltage
drop of the output reactor, etc.
Whether the motor
load or inertia is
too large?
Increase the ACC
time
Check the voltage of the
terminals of the motor with a
multimeter. Whether the voltage
is within the defined range?
Reduce the torque of
the load and
increase the capacity
of the inverter
