Description
Changing a fault level from default option [3] Trip Lock to [2] Trip
leads to the automatic reset of the alarm. For alarms involving
overcurrent, the drive has a hardware protection that issues a 3-
minute recovery after 2 consecutive overcurrent incidents. This
hardware protection cannot be overruled.
This option adds a delay between automatic resets, otherwise
it is the same as option [2] Trip. The delay prevents a situation
where reset is attempted repeatedly for an overcurrent situation.
Hardware protection of the drive forces the 3-minute recovery
time after 2 consecutive overcurrents (within a short time
window).
