All Modes
Sets the frequency at which DC Injection Braking starts when "Ramp to stop" (b1-03 = 0) is
selected.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the DC Injection Braking current as a percentage of the drive rated current.
All Modes
Sets the time of DC Injection Braking (Zero Speed Control when in CLV and CLV/PM) time at
start. Disabled when set to 0.00 s.
All Modes
Sets the time of DC Injection Braking (Zero Speed Control when in CLV and CLV/PM) at stop.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the magnetic flux compensation as a percentage of the no-load current value (E2-03).
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time for Short Circuit Braking operation at start.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the Short Circuit Braking operation time at stop.
V/f V/f w/PG
OLV/PM AOLV/PM
Determines the current level for Short Circuit Braking. Set as a percentage of the motor rated
current.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled
1: Enabled
V/f V/f w/PG
OLV/PM AOLV/PM
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.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets output frequency reduction time during Speed Search.
V/f V/f w/PG
OLV/PM AOLV/PM
Determines how much to lower the V/f ratio during Speed Search.
Output voltage during Speed Search equals the V/f setting multiplied by b3-04.
All Modes
When using an external contactor on the output side, b3-05 delays executing Speed Search after
a momentary power loss to allow time for the contactor to close.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the current injected to the motor at the beginning of Speed Estimation Speed Search. Set as
a coefficient for the motor rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
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
after a relatively long period of baseblock.
