Code Built-in keypad status Reason Action
Current stall
glitter
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;
Voltage stall
glitter
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.
Check whether the set
value of 01-06 (P.7), 01-07
(P.8) is too small
LV
Undervoltage
Input voltage is too low Supply normal voltage.
LT action
glitter
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.
