6-20
FUN-70: Stall Prevention Mode
FUN-71: Stall Prevention Level
This function is used to prevent the motor from stalling
by reducing the drive output frequency until the motor
current decreases below the stall prevention level.
When enabled (FUN-70 set to “yes”), this function is
active for all modes of operation: acceleration, steady
speed, and deceleration.
Note: FUN-71 is set as the percentage of DRV-05
[Rated Motor Current].
Note: When enabled, the maximum level will be
limited to 120% of Inverter rated Current.
Note: The stall level will be automatically reduced
if the drive is operated at the frequency higher than
base frequency.
Stall Prevention during Acceleration
Note: The actual Acceleration time may extend due
to stall prevention during Acceleration.
Note: The drive starts deceleration when a Stop
command is applied even while a motor stall state is
present.
Note: The output frequency and hence the motor
speed may oscillate due to stall prevention action
during constant run mode.
Note: The actual deceleration time (i.e. the time for
the motor to slow down or stop) may lengthen due
to stall prevention.
