input filter time constant (IN-07).
The wiring length between the inverter
and the motor is too long.
Ensure that the total cable length
between the inverter and the motor is
less than 200 m (50 m for motors
rated 3.7 kW or lower).
The motor does
not come to a
complete stop
when the inverter
output stops.
It is difficult to decelerate sufficiently,
because DC braking is not operating
normally.
Adjust the DC braking parameter.
Increase the set value for the DC
braking current.
Increase the set value for the DC
braking stopping time.
The output
frequency does
not increase to
the frequency
reference.
The frequency reference is within the
jump frequency range.
Set the frequency reference higher
than the jump frequency range.
The frequency reference is exceeding
the upper limit of the frequency
command.
Set the upper limit of the frequency
command higher than the frequency
reference.
Because the load is too heavy, the stall
prevention function is working.
Replace the inverter with a model
with increased capacity.
The cooling fan
does not rotate.
The control parameter for the cooling fan
is set incorrectly.
Check the control parameter setting
for the cooling fan.
