Stopping Method
Selection
Sets the method to stop the motor after removing a Run command or
entering a Stop command.
0
(0 - 3)
Note:
The setting range is 0, 1, and 3 when
A1-02 = 3, 4 [Control Method Selection = Closed Loop Vector, Advanced Open Loop Vector]
.
Select the appropriate stopping method for the application from the following four options.
0 : Ramp to Stop
The drive decelerates the motor to stop when the Stop command is entered (or when the Run command is
switched OFF).
The drive ramps the motor to stop according to the deceleration time. The default setting for the deceleration time
is
C1-02 [Deceleration Time 1]
. The actual deceleration time will vary depending on load conditions, such as
mechanical loss and inertia.
If the output frequency falls below or is equal to the value set in
b2-01 [DC Injection/Zero SpeedThreshold]
during deceleration, then the drive will perform DC Injection Braking, or Zero Speed Control, depending on the
control mode.

Parameter
b2-01
sets the frequency to begin DC Injection Braking at stop. If the output frequency falls below or
is equal to the value set in
b2-01
during deceleration, then the drive will perform DC Injection Braking for the
time set in
b2-04 [DC Inject Braking Time at Stop]
.

Note:
The drive will begin DC Injection Braking from the frequency set in
E1-09 [Minimum Output Frequency]
if
b2-01 ≤ E1-09
.
•
Ramping to Stop in Closed Loop Vector Control
Parameter
b2-01
sets the frequency to begin Zero Speed Control at stop. If the output frequency falls below or is
equal to the value set in
b2-01
during deceleration, then the drive will perform Zero Speed Control for the time
set in
b2-04
.

Note:
The drive will begin Zero Speed Control from the frequency set in
E1-09 [Minimum Output Frequency]
if
b2-01 ≤ E1-09
.
1 : Coast to Stop
The drive shuts OFF its output when the Stop command is entered (or when the Run command is switched OFF).
The motor coasts to stop.
Load conditions such as mechanical loss and inertia determine the deceleration rate as the motor coasts to stop.
