Sets the gain value that the drive multiplies by the V/f pattern output value during overexcitation
deceleration to calculate the overexcitation level.
Sets the function that injects harmonic signals during overexcitation deceleration.
0 : Disabled
1 : Enabled
Sets the upper limit of the current that is suppressed at the time of overexcitation deceleration as a
percentage of the drive rated current.
Sets the direction of motor rotation where the drive will enable overexcitation.
0 : Disabled
1 : Enabled Only when Rotating FWD
2 : Enabled Only when Rotating REV
Sets the feed forward function.
0 : Disabled
1 : Enabled
Sets the length of time for the motor to accelerate from the stopped to the maximum frequency with a
single motor at the rated torque. Inertia Tuning automatically sets the motor acceleration time.
Sets the ratio between load inertia and motor inertia. Inertia Tuning automatically sets the
Feedforward Control Gain value.
Sets the response frequency for the speed reference. Usually it is not necessary to change this
parameter.
Sets the type of motor data that Online Tuning uses for OLV control.
0 : Disabled
1 : Line-to-Line Resistance Tuning
2 : Voltage Correction Tuning
Sets the compensation gain when n6-01 = 2 [Online Tuning Selection = Voltage Correction Tuning].
Usually it is not necessary to change this parameter.
Sets the oscillation suppression gain for the low speed range.
Sets the response gain related to changes in the load.
Sets the speed calculation gain during usual operation. Usually it is not necessary to change this
setting.
Sets the speed calculation gain during a speed search.
