Chapter 4 - Parameter Description [FU1]

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.

Note: The set value is the percentage of FU2-33 [Rated Motor

Current].

Stall Prevention during

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.
