• When the protective function is activated after retries are attempted consecutively more than the number of times set in
Pr.67
, the Retry count excess fault (E.K) occurs and the converter output is shut off. (Refer to the figure of retry failure
example.)
• Use
Pr.68
to set the waiting time from when the converter output has been shut off until a retry is made in the range of 0 to
600 seconds.
• 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 (6 seconds at the shortest).
(When retry is successful, the cumulative number of retry failures is cleared.)
• Writing "0" in
Pr.69
clears the retry counter.
During a retry, the RTY signal is ON. For the RTY signal, set "11 (positive logic)" or "111 (negative logic)" in any of
Pr.11,
Pr.12, and Pr.16 (Output terminal function selection)
to assign the function.
NOTE
• Changing the terminal assignment using
Pr.11, Pr.12, or Pr.16
(Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
• Faults which trigger the retry operation can be selected with
Pr.65
. The faults not described in the following table do not
enable the retry function. (For the fault details, refer to
"
●
" indicates the fault selected.
NOTE
• Only the first fault is recorded in the fault history during retries.
• If a fault that does not trigger the retry operation occurs during retries, the converter output is shut off with the fault indication
after the retries finish.
• The fault reset by the retry function does not reset the accumulated data such as the electronic thermal relay function data.
(The reset result is different from the power-ON reset.)

When setting the retry function enabled, stay away from the motor and machine. The motor and machine will start suddenly (after the
reset time has elapsed) after the shutoff.
