If Number Of Autoreset Attempts (H46) = 0 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 after a delay defined by Auto-reset Delay (H47) subject to the minimum reset time allowed for the type of
trip. Note that for some trips the minimum is 10 s. The auto-reset count is only incremented when the trip is the same as the previous trip otherwise it
is reset to 0. When the auto-reset count reaches the programmed value, any further trip of the same value will not cause an auto-reset. If the number
of auto-reset attempts defined by Number Of Autoreset Attempts (H46) has not been reached and there has been no trip for 5 minutes then the auto-
reset count is cleared. Auto reset will not occur after any trips with priority levels 1, 2 or 3 as defined in Trip 0 (L29). When a manual reset occurs the
auto-reset counter is reset to zero.
If Number Of Autoreset Attempts (H46) = 6 the auto-reset counter is held at zero, and so there is no limit on the number of auto-reset attempts.
See Number Of Autoreset Attempts (H46).
