0: Disregarded. A new Run command needs to be issued after power up.
1: Allowed. Motor will start immediately after power up if a Run command is
already enabled.
Sets the frequency at which DC Injection Braking starts when "Ramp to stop"
(b1-03 = 0) is selected.
Sets the DC Injection Braking current as a percentage of the drive rated current.
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.
Sets the time of DC Injection Braking (Zero Speed Control when in CLV and
CLV/PM) at stop.
Sets the magnetic flux compensation as a percentage of the no-load current
value (E2-03).
Sets the time for Short Circuit Braking operation at start.
Sets the Short Circuit Braking operation time at stop.
Determines the current level for Short Circuit Braking. Set as a percentage of the
motor rated current.
0: Disabled
1: Enabled
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 output frequency reduction time during Speed Search.
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.
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.
Sets the current injected to the motor at the beginning of Speed Estimation
Speed Search. Set as a coefficient for the motor rated current.
