Description
b2: DC Injection Braking
Use b2 parameters to configure DC Injection Braking operation
Sets the frequency at which DC Injection Braking starts
when Ramp to Stop (b1-03 = 0) is selected. If b2-01< E1-
09, DC Injection Braking starts at E1-09.
Sets the DC Injection Braking current as a percentage of
the drive rated current.
Sets DC Injection Braking time at start. Disabled when set
to 0.00 seconds.
Sets DC Injection Braking time at stop.
When b1-03 = 2, actual DC Injection time is calculated as
follows:
(b2-04) x 10 x (Output Freq)/(E1-04). When b1-03 = 0, this
parameter sets the amount of DC Injection time applied to
the motor at the end of the decel ramp. Disabled when set to
0.00.
Sets the magnetic flux compensation as a percentage
of the no-load current value (E2-03).
Set as a percentage of the drive rated current.
An input terminal set for DC Injection Braking 2 (H1-
= 60) will make the drive use the current level set in b2-10
for DC Injection.
Sets the time for Short-Circuit brake operation at start.
Disabled when set to 0.00.
<22>
Sets the Short-Circuit brake operation time at stop. Used to
stop a motor rotating due to inertia. Disabled when set to
0.00 seconds.
<22>
b3: Speed Search
Use b3 parameters to configure Speed Search function operation.
Enables/disables the Speed Search function at start.
0: Disabled - Speed Search is not automatically performed
at start.
1: Enabled - Speed Search is automatically performed at
start.
Sets the current level at which the speed is assumed to be
detected and Speed Search is ended. Set as a percentage of
the drive rated current.
Sets the time constant used to reduce the output frequency
during Speed Search. Related to a change from max. output
frequency to 0.
In order to lower the output current when performing Speed
Search, this parameter determines what percentage the V/f
ratio should be reduced. The output voltage during Speed
Search becomes V/f x b3-04.
Delays the Speed Search operation after a momentary
power loss to allow time for an external output contactor to
close.
Sets the current injected to the motor at the beginning of
Estimation type Speed Search. Set as a factor of the motor
rated current.
Sets the gain which is applied to the speed detected by
Speed Estimation Speed Search before the motor is
reaccelerated. Increase this setting if ov occurs when
performing Speed Search.
Selects if Speed Search detects the motor rotation direction
during Speed Search.
0: Disabled–Frequency reference direction used
1: Enabled–Detected direction used
