Parameter
b2-01
sets the frequency to start Zero Speed Control at stop. When the output frequency is less than or
equal to the value set in
b2-01
during deceleration, the drive will do Zero Speed Control for the time set in
b2-04
.
Figure 12.12 Ramp to Stop in CLV and CLV/PM Control Methods
Note:
When
b2-01 ≤ E1-09
, the drive will start Zero Speed Control from the frequency set in
E1-09
.
1 : Coast to Stop
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output and coasts the
motor to stop.
Load conditions will have an effect on the deceleration rate as the motor coasts to stop (for example, mechanical loss
and inertia).
Figure 12.13 Coast to Stop
Note:
The drive ignores the Run command for the time set in
L2-03 [Minimum Baseblock Time]
when the Stop command is entered or when the
Run command is switched OFF. Do not enter the Run command until the motor comes to a complete stop. Use DC Injection or Speed Search
to restart the motor before it stops.
2 : DC Injection Braking to Stop
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output for the time set in
L2-03
. The drive waits for the minimum baseblock time and then injects the amount of DC current into the motor set
in
b2-02 [DC Injection Braking Current]
to stop the motor with DC current.
DC Injection Braking stops the motor more quickly than coast to stop.
Note:
If
A1-02 = 3, 4, 5, 6, or 7
, DC Injection Braking to Stop is not available.
