•
Assume that the rated full-load current of the inverter is 20A, P.62=5% and P.63=0.5s, in this case
if the output current is lower than 2
0
×
5%=1A for more than 0.5s, a signal(OMD) is output, which
is depicted in the figure below.
•
If the set value of P.62 or P.63 is 99999, the zero current detection is disabled.
