APPENDIX 353
7.3 Appendix 3 Warning Code List
When the output current is larger
than Stall prevention operation
level, the three lights on the left
side of the screen flicker, 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
on the right side of the screen
flicker, indicating that the inverter
is in voltage stall mode. Then the
motor may not run smoothly.
1、Add a brake resistor
between +/P and PR.
2、Check if the values of P.7
and P.8 are too small
Supply with the normal voltage
