455
The DC Injection Braking current level has an effect on the strength of the magnetic field that locks the motor
shaft. As the current level increases, the motor windings will supply more heat. Do not set this parameter higher
than the level that is necessary to hold the motor shaft.
■
b2-03: DCInj Time@Start
No.
(Hex.)
Name
Description
Default
(Range)
b2-03
(018B)
DCInj Time@Start
Sets the DC Injection Braking Time at stop.
0.00 s
(0.00 - 10.00 s)
This function stops then restarts a coasting motor and increases motor flux to make high starting torque (a process
called initial excitation). Set this parameter to 0.00 to disable the function.
Note:
To restart a coasting motor, use DC Injection Braking to stop and then restart the motor, or enable Speed Search. Enable DC Injection
Braking or Speed Search to prevent
ov [Overvoltage]
or
oC [Overcurrent]
faults.
■
b2-04: DCInj Time@Stop
No.
(Hex.)
Name
Description
Default
(Range)
b2-04
(018C)
DCInj Time@Stop
Sets the DC Injection Braking Time at stop.
Determined by A1-02
(0.00 - 10.00 s)
This function fully stops a motor with a large inertia during deceleration and will not let the inertia continue to
rotate the motor.
Set this parameter to 0.00 to disable the function.
When a longer time is required to stop the motor, increase the value.
■
b2-08: MagFlux Comp Value
No.
(Hex.)
Name
Description
Default
(Range)
b2-08
(0190)
MagFlux Comp Value
Sets how much current the drive injects when DC Injection Braking at Start starts (Initial
Excitation) as a percentage of
E2-03 [Mot No-Load Current]
.
0%
(0 - 1000%)
This parameter is effective when you start a high-capacity motor (a motor with a large secondary circuit time
constant). This function can quickly increase motor flux to make high starting torque (a process called initial
excitation).
The current level for DC Injection Braking at start changes linearly from the setting of
b2-08
to the setting of
b2-
03
as shown in
.
Figure 12.21 DC Current Level during DC Injection Braking at Start
Note:
•
If
b2-08 < 100%
, flux will develop very slowly.
•
When
b2-08 = 0%
, the DC current level will be the DC Injection current set in
b2-02 [DCI Braking Current]
.
•
If
b2-08
is set too high, DC Injection Braking at start can cause a large noise. Adjust
b2-08
to decrease the volume to the permitted
level.
