Stall Prevention
Level During Run This parameter is enabled when L3-05 is
set to “1” or “2”. MxC rated current is set
as 100%.
Decrease the set value if stalling or exces-
sive current occurs with the defaults.

Set the level as a percentage of the MxC
rated current.
Usually setting is not necessary. Lower
the value if the motor stalls at the default.
