⒊
C h e c k w h e t h e r t h e i n ve t e r ’s
capacity is too small and increase its
capacity.
⒋
Check whether there is a sudden
change in the power grid voltage.
Overcurrent
at decel
Overcurrent
at stopping
⒈
Check whether the insulation of the
output wires is good and whether the
motor has got short circuit.
⒉
Extend the deceleration time.
⒊
Replace it with an inverter of larger
capacity.
⒋
DC braking quantity is too high.
Decrease DC braking quantity.
⒌
The inverter has failure. Please send
it to the factory for repair.
Short circuit
to earth
⒈
Check whether the connection wire
of the motor has got short circuit.
⒉
Check whether the insulation of
the output wires is good.
⒊
Please send it for repair.
Overcoltage
at stopping
Overvoltage
at accel
Overvoltage
at constant
speed
Overvoltage
at decel
⒈
Extend the deceleration time or add
a braking resistor.
⒉
Improve the power grid voltage and
check whether theres is any voltage
leap happened.
