8.6.6 Overheat of the inverter
Inverter overheating
Clean the heat sink and
improve the condition
Reduce the carrier
frequency
If the it is the inverter
fault, please contact with
our company
If the it is the inverter
fault, please contact with
our company
Decrease the load and
increase the capacity of
the inverter
Add heat-releasing
device or derate the
inverter
Check if the ambient
temperature is too
high
Check if the carrier
frequency is too high
Check if the heat sink
is jammed
Check if there is
abnormal noise to the
fan of the inverter

8.6.7 Motor stall during ACC
Speed loss occurs to the
inverter during ACC
Check if the ACC time
is too short
If the it is the inverter fault or
interference, please contact
with our company
Overcurrent
If the it is the inverter
fault or interference,
please contact with our
company
Check if it performs
parameter autotune
