11.4 Retry [ r t r y ]
The retry function allows the drive to perform an auto-restart, when this feature
is desirable and applicable. The retry feature operates after a protective
function or parameter trips the drive.
CAUTION:
Before using the retry function confirm that there will be no problems with
the load or application when an automatic restart occurs. Certain large
inertia loads, or loads requiring large torque boost to start may not work
properly with the retry feature. Also, personnel safety is an obvious
consideration.
