11.7 Retry function
11.7
Retry function
This function allows the inverter to reset itself and restart at activation of the protective function (fault indication). The retry
generating protective functions can also be selected.
When the automatic restart after instantaneous power failure function is selected (
Pr.57 Restart coasting time
≠
"9999"), the
restart operation is also performed after a retry operation as well as after an instantaneous power failure. (For restart operation,
refer to
and
for selection.)
Setting the retry function (Pr.67, Pr.68)
• When the inverter protective function is operating (fault indication), the retry function automatically cancels (resets) the
protective function after the time set in
Pr.68
. The retry function then restarts the operation from the starting frequency.
• The retry function is enabled when the
Pr.67
setting is other than "0". Set the number of retries at activation of the protective
function in
Pr.67
.
• When retries fail consecutively more than the number of times set in
Pr.67
, a retry count excess (E.RET) occurs, resulting
in an inverter retries. (Refer to the Retry failure example.)
• Use
Pr.68
to set the waiting time from a protective function activation to a retry in the range of 0.1 to 600 s.
• During retry operation, the During retry (Y64) signal is ON. For the Y64 signal, set "64" (positive logic) or "164" (negative
logic) in any parameter from
Pr.190 to Pr.196 (Output terminal function selection)
to assign the function.
Retry count check (Pr.69)
• Reading the
Pr.69
value provides the cumulative number of successful restart times made by retries. The cumulative count
in
Pr.69
increases by 1 when a retry is successful. Retry is regarded as successful when normal operation continues
without a fault for the
Pr.68
setting multiplied by four or longer (3.1 seconds at the shortest). (When retry is successful, the
cumulative number of retry failures is cleared.)
