Description
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time used to detect oL7 [High Slip Braking Overload], which occurs when the
output frequency does not change during high-slip braking. Usually it is not necessary
to change this parameter.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain value that the drive multiplies by the V/f pattern output value during
overexcitation deceleration to calculate the overexcitation level.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the function that injects harmonic signals during overexcitation deceleration.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the upper limit of the current that is suppressed at the time of overexcitation
deceleration as a percentage of the drive rated current.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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
Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the feed forward function.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the ratio between load inertia and motor inertia. Inertia Tuning automatically sets
the Feedforward Control Gain value.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the response frequency for the speed reference. Usually it is not necessary to
change this parameter.
Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the compensation gain when n6-01 = 2 [Online Tuning Selection = Voltage
Correction Tuning]. Usually it is not necessary to change this parameter.
Description
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the oscillation suppression gain for the low speed range.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the response gain related to changes in the load.
