Appendix 3：Warning code list
Appendix 201
7.3 Appendix 3：Warning code list
When the output current is
greater than the stall level, the
three small lights at the top
right of the built-in keypad will
flash, indicating that the
inverter is currently in a current
stall state, and the motor will
not run smoothly.
1. Check whether the
setting of 06-01 (P.22),
06-02 (P.23), 06-03 (P.66)
is reasonable;
2. Check whether the set
value of 01-06 (P.7), 01-07
(P.8) is too small;
If the DC bus voltage is too
high, inverter will be in a
voltage stall state, and the
three small lights at the bottom
right of the built-in keypad will
flash, and the motor will not run
smoothly.
1.Add a regenerative
braking resistor between
the main circuit terminals P
and PR；
2.Check whether the set
value of 01-06 (P.7), 01-07
(P.8) is too small
When the inverter output
current is higher than twice the
rated current, but does not
reach the overcurrent level, the
six small lights on the right side
of the built-in keypad will flash,
indicating that the inverter is
now in LT state, and the motor
will not run smoothly.
1. If there is rapid
acceleration or rapid
deceleration, please extend
the acceleration and
deceleration time
2. Avoid sudden increase in
load
3. Check whether there is a
short circuit at the motor
terminal U/T1-V/T2-W/T3
Note: The function of the above warning is to inform the customer of the current working condition of the inverter. The
inverter will not stop. Please adjust the parameter value appropriately or confirm the power supply and load status.
