V/f
OLV
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.
All Modes
Sets the switching level when the search method is automatically switched in
accordance with the size of the motor's residual voltage.
V/f OLV
Sets the dead-band width for the current detected in a Speed Search.
V/f OLV
Sets the Speed Search restart current level as a percentage of the drive rated
current.
V/f OLV
Sets the time to detect Speed Search restart.
V/f
OLV
Sets the number of times the drive can attempt to restart when performing
Speed Search.
V/f OLV
Sets the time the must wait between each Speed Search restart attempt.
V/f OLV
Sets the primary delay time of the torque compensation function during
Speed Search, in ms units.
V/f OLV
Sets the level at which to start the operation to extend the voltage recovery
time in order to suppress the current when the voltage is recovered during
Speed Search. The setting is made by assuming the motor no-load current is
1.0.
V/f OLV
Sets the time constant to filter the level for extending the voltage recovery
time to suppress the current when the voltage is recovered during Speed
Search.
V/f OLV
Sets the waiting time between the end of Speed Search and the switch to
normal control. The frequency reference is maintained during this time.
V/f OLV
Sets the current limit value of the software during Speed Search. Set as a
percentage of the motor rated current.
V/f OLV
Sets the current limit value for the software when the frequency reference
value is 0 to 6 Hz during Speed Search. Set as a percentage of the motor
rating.
