V/f V/f w/PG
OLV/PM AOLV/PM
Sets the output frequency reduction step width for when the drive stops the motor using HSB.
Set as a percentage of the maximum output frequency. Increase this setting if overvoltage
occurs during HSB.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the current limit during HSB as a percentage of the motor rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time the drive will run with minimum frequency (E1-09) at the end of deceleration.
If this time is set too low, the machine inertia can cause the motor to rotate slightly after HSB.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time required for an HSB overload fault (oL7) to occur when the drive output
frequency does not change during an HSB stop. This parameter does not typically require
adjustment.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the gain applied to the V/f pattern during Overexcitation Deceleration (L3-04 = 4).
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled
1: Enabled
V/f V/f w/PG
OLV/PM AOLV/PM
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.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Enabled in both directions
1: Enabled only when rotating forward
2: Enabled only when in reverse
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled
1: Enabled
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time required to accelerate the motor at the rated torque from stop to rated speed.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the ratio between motor and load inertia. Lower this setting if overshoot occurs at the end
of acceleration.
