Stopping Methods
This section explains methods of stopping the Inverter.
Selecting the Stopping Method when a Stop Command is Sent
There are two methods of stopping the Inverter when a Stop Command is sent:
Deceleration to stop
•
Coast to stop
•
Set constant b1-03 to select the Inverter stopping method.

Setting
Description
Range
Used to set the stopping
method used when a Stop Com-
mand is input.
0 or 1
0: Deceleration to stop
1: Coast to stop
Used to set the method of
operation when the frequency
reference input is less than the
minimum output frequency
(E1-09).
0: Run at frequency reference
(E1-09 not effective).
0 to 3
1: STOP (Frequencies below
E1-09 in the coast to stop
state.)
2: Run at min. frequency.
(E1-09)
3: Run at zero-speed (Frequen-
cies below E1-09 are zero)
Used to set the frequency
which starts DC injection brak-
ing in 1% units when decelera-
0.00 to
tion to stop is selected.
10.00
When b2-01 is less than E1-09,
E1-09 becomes the DC injec-
tion braking starting frequency.
Sets the DC injection braking
current as a percentage of the
Inverter rated current.
Used to set the time to perform
DC injection braking at start in
units of 1 second.
Used to stop coasting motor
and restart it. When the set
10.00
value is 0, DC injection braking
at start is not performed.
Used to set the time to perform
DC injection braking at stop in
units of 1 second.
Used to prevent coasting after
the Stop Command is input.
10.00
When the set value is 0.00, DC
injection braking at stop is not
performed.
