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.

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
