F.oC1
.
Over-current in
Acc process
Too short Acc time
Prolong the Acc
time
V/F curve is not
suitable
Check and adjust
V/F curve, adjust
torque boost or
set the motor
parameters
correctly to
ensure the
normal auto
torque boost
works well.
Low AC supply voltage
Check the
inverter input AC
supply
Moment of inertia of
the load is too large,
heavy impact load
Reduce the load
of mutations,
prolong the Acc
time
The rotating motor
re-starts after the
inverter stops instantly
Start when the
motor absolutely
stops
Motor parameter
setting is not normal
Properly set
motor parameters
Inverter power is too
small
Select a higher
power inverter
F.oC2
.
Over-current in
Dec process
Too short Dec time
Prolong the Dec
time
Load inertia is too high
Connect suitable
braking device
