1.there is external force to
drag the motor to run when
running
2.the input voltage is high
The range of input voltage is

buffer resistance are abnormal
5.the drive panel is abnormal.
6.the control panel is
abnormal
1.the type selection of inverter
is small
2.whether the load is too large
or the motor stall occurs
1. power grid voltage is too
low

or install braking resistor.
3.increase the deceleration
time
4.install braking unit and
brake resistor
1.cancel the external force
or install braking resistor.
2.set the voltage to the
normal range
Adjust the voltage to the
range of the requirements
of specification
1.reset fault
2.adjust the voltage to the
normal range
3.seek for technical
support
1.choose the inverter with
large power level
2.reduce the load and
check the motor and its
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
