5.29 Zero Current Detection (P.62, P.63)
P.62 “Zero current detection level”
P.63 “Zero current detection time”
Related parameters
P.40 “Multi-function output
terminal pattern”
P.85 “Function selection for
multi-function relay”
Parameter Factory Setting Setting Range Remarks
62 5% 0~200%, 9999 9999: Function invalid
63 0.5s 0.05~60s, 9999 9999: Function invalid
<Setting>
• 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.
5.30 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 time at alarm”
● When an alarm occurs, previous status before the alarm will be restored automatically, which is
called ‘retry’.
● Inverter retry is a conditional execution. For example, when the first alarm occurs, the retry will be
