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.
