Retry function

If an alarm occurs, the inverter resets itself automatically to restart. You can also select the alarm
description for a retry.
When automatic restart after instantaneous power failure is selected (Pr. 57 "Restart coasting
time" ≠ 9999), restart operation is performed at retry operation as at an instantaneous power fail-
ure. (Refer to section 6.16.1 for the restart function.)
