is too low.
Adopt
forward/reverse speed
tracking and restart
function (STR function)
(f500 = 1)
Set f418= 2.
e-21
Inverter
overload
Acceleration
time is too short.
DC braking
current level is
too high.
V/f parameter
is wrongly set.
When the
inverter starts,
the load is still in
rotation.
The load is too
large.
Increase acceleration
parameter (f007 or
f617).
Reduce the setting of
f606 and f607.
Correctly set V/f
parameter.
Set parameter f501 =
2.
Use an inverter with
higher rated power.
e-22
Motor
overload
V/f parameter
is wrongly set.
The motor is
blocked.
The motor
continues to run
at low speed.
The load
applied to the
motor is too
large.
Correctly set V/f
parameter.
Check the load.
