HSB Dwell Time at Stop
Sets the dwell time, a length of time when high-slip braking is ending and during which the
motor speed decreases and runs at a stable speed. For a set length of time, the drive will
hold the actual output frequency at the minimum output frequency set in E1-09.

HSB Overload Time
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.

OverexcitationBraking
(OEB) Gain
Sets the gain value that the drive multiplies by the V/f pattern output value during
overexcitation deceleration to calculate the overexcitation level.

Motor Inertia
Acceleration Time
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.
