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

HSB CurrLim Level
Sets the maximum current output during high-slip braking as a percentage, where E2-01
[Mot Rated Current (FLA)] is 100%. Also set the current suppression to prevent
exceeding drive overload tolerance.
Note:
The upper limit to the setting range changes when the setting for C6-01 [ND/HD
Duty Selection] changes.
• 150% when C6-01 = 0 [HD Rating]
• 120% when C6-01 = 1 [ND Rating]

HSB DwellTime@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.
