mechanical conditions
1.check the power grid
voltage
2.correctly set this
parameter.
3.reduce the load and
check the motor and its
mechanical conditions
1.replace the drive, the
power board or contactor
2.seek for technical
support
3.check and eliminate
the existing problems in
the peripheral line
1.eliminate peripheral
faults
2.check the motor's
three-phase winding is
normal or not and
eliminate faults
3.seek for technical
support
1.clean up the air duct
2.replace the fan
3.decrease the ambient
temperature
4.replace the thermistor
5.replace the inverter
module
