Function:
Select to trip the drive or issue a warning if the
drive detects a severe mains imbalance. Operation
under severe main imbalance conditions reduces
the life time of the unit. It is severe if the drive
is operated continously near nominal load (i.e.
running a pump or fan near full speed).

Infinite Automatic Reset
Function:
Selects the reset function after tripping. Upon reset,
you can restart the frequency converter.
If you select Manual reset [0], carry out reset
via [RESET] or via the digital inputs. If you
want the frequency converter to carry out an
automatic reset (1-10 times) after tripping,
select data value [1]-[10].
NB!:
If the number of AUTOMATIC RESETs
is reached within 10 minutes, the
frequency converter enters Manual reset
[0] mode. When a Manual reset is performed, the
parameter setting is back in force. If the number
of AUTOMATIC RESETs is not reached within 10
minutes, the internal AUTOMATIC RESET counter
is reset. Also, if a Manual reset is performed, the
internal AUTOMATIC RESET counter is reset.
The motor may start without a warning.
