<Setting>
• Assume the inverter's rated is full-loaded, the current is 20A, P.62=5% and P.63=0.5s, then
when the output current is smaller than 20×5%=1A and exceeding 0.5s, OMD will send out
signals.

• If the set value of P.62 or P.63 is 99999, the zero current detection function is disabled.
Note: In this paragraph, OMD is the function name for “multi-function output terminal”. Please refer
to P.40. For wiring, please refer to Section 3.5.
5.32 Retry Function (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 time at alarm”
● When an alarm goes off, a “retry" will take place to restore the previous setting.
● Inverter's retry is performed conditionally. When the alarm goes off and the inverter has an
automatic retry, the re-occurrence of alarm going off before a set time is called a
“continuous alarm”. If continuous alarms happen for more than a set time, there is a
significant malfunction. In this case, manual trouble shooting is necessary. The inverter at
this point will perform no more the retry function. The number of Pre-defined occurrence is
called “number of retries at abnormality (P.67)”.
● If none of the alarm belongs to "continuous alarms”, the inverter will perform retry for
unlimited times.
● The period from the moment of alarm to that of retry is defined as “retry waiting time
”
.
