HSB Deceleration
Frequency Width
Sets the amount by which the output frequency is to be lowered during high-slip braking,
as a percentage of E1-04 [Maximum Output Frequency], which represents the 100% value.

HSB Current Limit Level
Sets the maximum current output during high-slip braking as a percentage of E2-01 [Motor
Rated Current (FLA)]. Also set the current suppression to prevent exceeding drive
overload tolerance.
Note:
The upper limit of the setting range changes when the setting for C6-01 [Normal /
Heavy Duty Selection] changes.
• 150% when C6-01 = 0 [Heavy Duty Rating 1 (HD1) for Constant Torque
Applications].
• 110% when C6-01 = 1 [Normal Duty Rating 1 (ND1) for Variable Torque
Applications].

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.
