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.

HSB Current Suppression
Level
Sets the upper limit of the current that is suppressed at the time of overexcitation deceleration as a
percentage of the drive rated current.

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.

Feed Forward Control Gain
Sets the ratio between load inertia and motor inertia. Inertia Tuning automatically sets the
Feedforward Control Gain value.
