If the feedback value
and the set point
deviation are both is
0.15 kg (3 kg × 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. The deceleration
time is according to the
Deceleration Time 2 set
in Pr.01.12. When the
feedback value is less
than 2.85 kg, the drive
starts to run.

Liquid Leakage:
Assume that when the
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 ×
4% = 0.12 kg) within 2
second. When the
feedback value
continues to decrease to
make the deviation of
the set point be less
than 0.99 kg (3 kg ×
33% = 0.99 kg), that is,
when the feedback value
is less than 2.01 kg, the
drive starts to run.
