Operation setting at alarm occurrence Parameter
6 - 170
Retry operation automatically resets a fault and restarts the inverter at the starting frequency when
the time set in Pr. 68 elapses after the inverter is tripped.
Retry operation is performed by setting Pr. 67 to any value other than "0". Set the number of retries at
fault occurrence in Pr. 67. When retries fail consecutively more than the number of times set in Pr. 67,
a retry count excess fault (E.RET) occurs, resulting in inverter trip.
(Refer to retry failure example in 6-88.)
Use Pr. 68 to set the waiting time from when the inverter trips until a retry is made in the range 0.1 to
360 s. (When the setting value is "0 s", the actual time is 0.1 s.)
Reading the Pr. 69 value provides the cumulative number of successful restart times made by retry.
The cumulative count in Pr. 69 is increased by 1 when a retry is regarded as successful after normal op-
eration continues without faults occurring for more than four times longer than the time set in Pr. 68
after a retry start. (When retry is successful, cumulative number of retry failure is cleared.) Writing "0"
to Pr. 69 clears the cumulative count.
During a retry, the Y64 signal is on. For the Y64 signal, assign the function by setting "64" (positive op-
eration) or "164" (negative operation) to any of Pr. 190 to Pr. 192 "Output terminal function selection".
