•
Assume that the rated full-load current of the inverter is 20A, P.62=5%, P.63=0.5s, and the output
current is lower than 20 5%=1A for more than 0.5s, a signal (OMD) is output (as shown in the
figure below).
•
If the set value of P.62 or P.63 is 9999, the zero current detection is disabled.
Note: In this section, OMD is one of the function names of the multi-function output terminal. Please refer to
P.40
for function selection and features, and
Section 3.5.6
for wiring.
5.28 Retry (P.65, P.67, P.68, P.69)
P.65 “Retry selection”
P.67 “Number of retries at alarm occurrence”
P.68 “Retry waiting time”
P.69 “Retry accumulation times”
When an alarm occurs, the previous states before the alarm will be restored automatically, which is
called ‘retry’.
