When the
feedback value
and the set point
deviation are both
0.15 kg (3 kg X
5%=0.15 kg), that
is, when feedback
value is ≥ 2.85 kg
and time > 10
seconds, the AC
motor drive starts
to decelerate to
stop. This
deceleration time
is according to the
Deceleration Time
2 in Pr.01.12.
When the
feedback value is
< 2.85 kg, the AC
motor drive starts
to run.

Liquid Leakage:
Assume that when
the AC motor drive
does not run and
is in a constant
pressure status,
the variation of the
feedback value is
less than 0.12 kg
(3 kg X 4% = 0.12
kg) within 2
seconds. When
the feedback
value continues to
decrease to make
the deviation of
the set point be
less than 0.99 kg
(3 kg X 33% =
0.99 kg), that is,
when the
feedback value is
less than 2.01 kg,
the
AC motor drive
starts to run.
Liquid Usage after
Liquid Leakage:
Assume that when
the AC motor drive
does not run and
is in a constant
pressure status,
the variation of the
feedback value is
higher than 0.12
kg (3 kg X 4% =
0.12 kg) within 2
seconds, the AC
motor drive starts
to run.
