V/f V/f V/f w PG V/f w PG
OLV/PM AOLV/PM CLV/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 V/f w PG V/f w PG
OLV/PM AOLV/PM CLV/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 V/f V/f V/f w PG V/f w PG V/f w PG V/f w PG
OLV/PM OLV/PM AOLV/PM AOLV/PM CLV/PM CLV/PM
Sets the gain applied to the V/f pattern during Overexcitation Deceleration
(L3-04 = 4).

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.

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.
