If Pr 10.34 is set to zero then no auto reset attempts are made. Any other value will cause the drive to automatically reset following a trip for the
number of times programmed. Pr 10.35 defines the time between the trip and the auto reset (this time is always at least 10s for OI.AC, OI.br trips,
etc.). The reset count is only incremented when the trip is the same as the previous trip, otherwise it is reset to 0. When the reset count reaches the
programmed value, any further trip of the same value will not cause an auto-reset. If there has been no trip for 5 minutes then the reset count is
cleared. Auto reset will not occur on a UU, Et, EEF or HFxx trips. When a manual reset occurs the auto reset counter is reset to zero.
If this parameter is 0 then Pr 10.01 (Drive healthy) is cleared every time the drive trips regardless of any auto-reset that may occur. When this
parameter is set the 'Drive healthy' indication is not cleared on a trip if an auto-reset is going to occur.
If stop on low priority trips is selected the drive will stop before tripping except in regen mode where the drive trips immediately. Low priority trips are:
th, ths, Old1, cL2, cL3, SCL.
