6.13 Operation setting at alarm occurrence
6.13.1 Retry function (Pr. 65, Pr. 67 to Pr. 69)
If a fault occurs, the inverter resets itself automatically to restart. You can also select the fault for a retry.
When you have selected automatic restart after instantaneous power failure (Pr. 57 "Restart coasting
time" "9999"), restart operation is performed at the retry operation time which is the same of that of
a power failure. (Refer to section 6.12.1 for the restart function.)
The above parameters can be set when Pr. 160 "User group read selection" = 0.
