Sets DC Injection Braking time at stop.
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.
Sets the amount of output current during Speed Estimation Speed Search as a
coefficient for the no-load current.
Sets the proportional gain for the current controller during Speed Search.
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.
Sets the minimum current detection level during Speed Search.
0: Disabled (uses the direction of the frequency reference)
1: Enabled (drive detects which way the motor is rotating)
Sets the Speed Search restart current level as a percentage of the drive rated
current.
Sets the time to detect Speed Search restart.
Sets the number of times the drive can attempt to restart when performing
Speed Search.
0: Current Detection
1: Speed Estimation
Sets the time the drive must wait between each Speed Search restart attempt. Default: 0.5 s
Sets the level that determines the direction of motor rotation.
Selects a condition to activate Speed Search Selection at Start (b3-01) or
External Speed Search Command 1 or 2 from the multi-function input.
0: Triggered when a Run command is issued (normal).
1: Triggered when an external baseblock is released.
