FU1-59: Stall Prevention Mode Selection (Bit set)
FU1-60: Stall Prevention Level
This bit set parameter follows the conventions used in
I/O-15 and I/O-16 to show the ON (bit set) status.
This function is used to prevent the motor from stalling
by reducing the inverter output frequency until the motor
current decreases below the stall prevention level. This
function can be selected for each mode of acceleration,
steady speed, and deceleration via bit combination.

Deceleration
When FU1-59 is set to ‘111’, stall prevention works during
accelerating, steady speed and decelerating.
☞
Note:
The acceleration and deceleration time may take
longer than the time set in DRV-01, DRV-02 when Stall
Prevention is selected.
☞
Note:
If stall prevention status persists, inverter may stop
during acceleration.
