Running time
reached
The actual running time of the
inverter is longer than the
preset running time.
Ask the supplier to adjust the
preset running time.
OL3
Electrical overload
The inverter will report
overload pre-alarm according
to the set value.
Check the load and the overload
pre-alarm points.
dEu
Velocity deviation
fault
The load is too heavy or
stalled.
1. Check the load and ensure it
is normal. Increase the detection
time.
2. Check whether the control
parameters are normal.
STo
Maladjustment fault
1. The control parameters of
the synchronous motors not
set properly.
2. The autotuning parameter
is not correct.
3. The inverter is not
1. Check the load and ensure it
is normal.
2. Check whether the control
parameter is set properly or not.
3. Increase the maladjustment
