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.
Default: 1.0 s

output frequency does not change during an HSB stop. This parameter does
not typically require adjustment.

Overexcitation Deceleration. Set as a percentage of the drive rated current.
