High-Slip Braking
Overload Time
HSB OL Time
V/f V/f
Sets the time required for an HSB overload fault (oL7) to occur
when the drive output frequency does not change during an HSB
stop. This parameter does not typically require adjustment.
Default: 40 s
Min.: 30
Max.: 1200

High-Slip Suppression
Current Level
Hflux I Supp Lvl

the overexcitation gain in order to prevent a too high motor slip
during Overexcitation Deceleration. Set as a percentage of the
drive rated current.
