When the output current is larger
than Stall prevention operation
level, the three lights at the upper
left of the screen will blink,
indicating that the inverter is in
current stall mode. In this case
the motor may not run smoothly.
Check if the values of P.22,
P.23, and P.66 are proper.
Check if the values of P.7 and
P.8 are too small.
If there is rapid acceleration
or
deceleration,
please
extend the acceleration and
deceleration time.
Avoid sharp increase of load
Check whether there is a
short circuit in the motor
terminal U/ t1-v/t2-w /T3.

When the voltage between +/P
and -/N is too high, the three
lights at the bottom left of the
screen will blink, indicating that
the inverter is in voltage stall
mode. Then the motor may not
run smoothly.
1、Add a brake resistor
b/P and PR.
2、Check if the values of P.7
