Sets output current level at which the drive will start reducing the
overexcitation gain in order to prevent a too high motor slip during
Overexcitation Deceleration. Set as a percentage of the drive rated current.
0: Enabled in both directions
1: Enabled only when rotating forward
2: Enabled only when in reverse
0: Disabled
1: Enabled
Sets the time required to accelerate the motor at the rated torque from stop to
rated speed.
Sets the ratio between motor and load inertia. Lower this setting if overshoot
occurs at the end of acceleration.
0: Disabled
1: Line-to-line resistance tuning
2: Voltage correction. Setting not possible when Energy Saving is enabled
(b8-01).
Decrease this setting for motors with a relatively large rotor time constant. If
overload occurs, increase this setting slowly in increments of 0.10.
Sets the current used for initial rotor position estimation as a percentage of the
motor rated current (E5-03). If the motor nameplate lists an "Si" value, that
value should be entered here.
Sets the current during initial polar attraction as a percentage of the motor rated
current. Enter a high value when attempting to increase starting torque.
0: Pull-in
1: High frequency injection
2: Pulse injection
Increase this setting if hunting occurs. Decrease to lower the response.
Sets the time constant to make the pull-in current reference and actual current
value agree. Decrease the value if the motor begins to oscillate, and increase
the value if it takes too long for the current reference to equal the output current.
Defines the d-Axis current reference during no-load operation at a constant
speed. Set as a percentage of the motor rated current. Increase this setting if
hunting occurs while running at constant speed.
