Figure 12.9 Ramp to Stop with V/f and OLV Control Methods
Note:
When
b2-01 ≤ E1-09 [Min Output Frequency]
, the drive will start DC Injection Braking from the frequency set in
E1-09
.
•
Ramp to Stop with OLV/PM, AOLV/PM, and EZOLV Control Methods
Parameter
b2-01
sets the frequency to start Short Circuit Braking. When the output frequency is less than or
equal to the value set in
b2-01
during deceleration, then the drive will do Short Circuit Braking for the time set
in
b2-13 [SCB Time@Stop]
. When
b2-04 ≠ 0
, the drive will do DC Injection Braking for the time set in
b2-04
when Short Circuit Braking is complete.
Figure 12.10 Ramp to Stop with OLV/PM, AOLV/PM, and EZOLV Control Methods
Note:
When
b2-01 ≤ E1-09
, the drive will start Short Circuit Braking from the frequency set in
E1-09
.
If
b2-01 = 0 Hz
and
E1-09 = 0 Hz
, the drive will not do Short Circuit Braking.
1 : Coast->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 12.11 Coast to Stop
Note:
When you enter the Stop command or turn OFF the Run command, the drive ignores the Run command for the time set in
L2-03 [Min
Baseblck Time]
. 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 Inj->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 [DCI 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 = 5, 6
, DC Injection Braking to Stop is not available.
