Load conditions will have an effect on the deceleration rate as the motor coasts to stop (for example, mechanical loss
and inertia).
Figure 5.4 Coast to Stop
Note:
The drive ignores the Run command for the time set in
L2-03 [Minimum Baseblock Time]
when you enter a Stop command or switch OFF
the Run command. Make sure that the motor stops completely before you enter a Run command. 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.
b2-02: DC Injection Braking Current
b2-04: DC Inject Braking Time at Stop
L2-03: Minimum Baseblock Time
Figure 5.5 DC Injection Braking to Stop
The value set in
b2-04
and the output frequency when the drive receives the Stop command determine the DC
Injection Braking time. The drive calculates the DC Injection Braking time as in
.
